• sur KAN T&IT Blog: Simplificá tu Análisis Geoespacial con KICa, el Innovador Plugin de QGIS para acceder a catálogos de Imágenes

  Publié: 10 November 2023, 9:04pm CET

  Pièce jointe: [télécharger]

  KICa, «Kan Imagery Catalog», es un plugin para QGIS. Esta herramienta innovadora simplifica el acceso a catálogos de imágenes satelitales, en un principio, utilizando metodología estándar como es STAC (sigla en inglés de Catálogos de Recursos Espacio- Temporales) el cual es un lenguaje único para el acceso a catálogos de imágenes satelitales de una manera estándar y uniforme. Esto nos permite tener un objetivo agnóstico basado en la posibilidad de centrarnos en la necesidad de resolver nuestro análisis geoespacial sobre una zona y no tener que estar buscando cada uno de los proveedores por separado. 

  En un principio se incorporan proveedores de imágenes satelitales (gratuitas y comerciales), pero está previsto, en las siguientes versiones, incorporar imágenes de drones, vuelos entre otros recursos que faciliten el análisis geoespacial. Hoy podrán observar que están disponible los proveedores como UP42 o Sentinel Hub, dentro de una región geográfica definida por el usuario. 

  Con este potente plugin, los usuarios tienen la capacidad de explorar de manera eficiente los catálogos disponibles, así como consultar pisadas (footprints) y vistas rápidas (quicklooks) de las imágenes que se encuentran en su área de interés para estimar su uso sin la necesidad de ser descargada la imagen completa para su análisis.

  Así, este plugin se convierte en una herramienta esencial para todos aquellos que trabajan con datos geoespaciales, ya que les proporciona un acceso rápido y sencillo a imágenes satelitales, facilitando tanto el análisis como la visualización de datos. No importa si sos un profesional en el campo de la geoinformación, un científico de datos o un entusiasta de la cartografía; «KICa» enriquecerá tu flujo de trabajo y mejorará tus capacidades de exploración y utilización de imágenes satelitales. 

  Nuestra solución es de código abierto y colaborativa, por lo que te invitamos a visitar nuestro repositorio donde podrás ver más documentación, reportar bugs y nuevas mejoras, y también contribuir en el código con tus “push request”. 

  ¡Optimizá tus proyectos geoespaciales con esta valiosa herramienta!

• sur Free and Open Source GIS Ramblings: Bringing QGIS maps into Jupyter notebooks

  Publié: 10 November 2023, 7:03pm CET

  Earlier this year, we explored how to use PyQGIS in Juypter notebooks to run QGIS Processing tools from a notebook and visualize the Processing results using GeoPandas plots.

  Today, we’ll go a step further and replace the GeoPandas plots with maps rendered by QGIS.

  The following script presents a minimum solution to this challenge: initializing a QGIS application, canvas, and project; then loading a GeoJSON and displaying it:

  from IPython.display import Image
  
  from PyQt5.QtGui import QColor
  from PyQt5.QtWidgets import QApplication
  
  from qgis.core import QgsApplication, QgsVectorLayer, QgsProject, QgsSymbol, \
      QgsRendererRange, QgsGraduatedSymbolRenderer, \
      QgsArrowSymbolLayer, QgsLineSymbol, QgsSingleSymbolRenderer, \
      QgsSymbolLayer, QgsProperty
  from qgis.gui import QgsMapCanvas
  
  app = QApplication([])
  qgs = QgsApplication([], False)
  canvas = QgsMapCanvas()
  project = QgsProject.instance()
  
  vlayer = QgsVectorLayer("./data/traj.geojson", "My trajectory")
  if not vlayer.isValid():
      print("Layer failed to load!")
  
  def saveImage(path, show=True): 
      canvas.saveAsImage(path)
      if show: return Image(path)
  
  project.addMapLayer(vlayer)
  canvas.setExtent(vlayer.extent())
  canvas.setLayers([vlayer])
  canvas.show()
  app.exec_()
  
  saveImage("my-traj.png")
  

  When this code is executed, it opens a separate window that displays the map canvas. And in this window, we can even pan and zoom to adjust the map. The line color, however, is assigned randomly (like when we open a new layer in QGIS):

  

  To specify a specific color, we can use:

  vlayer.renderer().symbol().setColor(QColor("red"))
  
  vlayer.triggerRepaint()
  canvas.show()
  app.exec_()
  saveImage("my-traj.png")
  

  

  But regular lines are boring. We could easily create those with GeoPandas plots.

  Things get way more interesting when we use QGIS’ custom symbols and renderers. For example, to draw arrows using a QgsArrowSymbolLayer, we can write:

  vlayer.renderer().symbol().appendSymbolLayer(QgsArrowSymbolLayer())
  
  vlayer.triggerRepaint()
  canvas.show()
  app.exec_()
  saveImage("my-traj.png")
  

  

  We can also create a QgsGraduatedSymbolRenderer:

  geom_type = vlayer.geometryType()
  myRangeList = []
  
  symbol = QgsSymbol.defaultSymbol(geom_type)
  symbol.setColor(QColor("#3333ff"))
  myRange = QgsRendererRange(0, 1, symbol, 'Group 1')
  myRangeList.append(myRange)
  
  symbol = QgsSymbol.defaultSymbol(geom_type)
  symbol.setColor(QColor("#33ff33"))
  myRange = QgsRendererRange(1, 3, symbol, 'Group 2')
  myRangeList.append(myRange)
  
  myRenderer = QgsGraduatedSymbolRenderer('speed', myRangeList)
  vlayer.setRenderer(myRenderer)
  
  vlayer.triggerRepaint()
  canvas.show()
  app.exec_()
  saveImage("my-traj.png")
  

  

  And we can combine both QgsGraduatedSymbolRenderer and QgsArrowSymbolLayer:

  geom_type = vlayer.geometryType()
  myRangeList = []
  
  symbol = QgsSymbol.defaultSymbol(geom_type)
  symbol.appendSymbolLayer(QgsArrowSymbolLayer())
  symbol.setColor(QColor("#3333ff"))
  myRange = QgsRendererRange(0, 1, symbol, 'Group 1')
  myRangeList.append(myRange)
  
  symbol = QgsSymbol.defaultSymbol(geom_type)
  symbol.appendSymbolLayer(QgsArrowSymbolLayer())
  symbol.setColor(QColor("#33ff33"))
  myRange = QgsRendererRange(1, 3, symbol, 'Group 2')
  myRangeList.append(myRange)
  
  myRenderer = QgsGraduatedSymbolRenderer('speed', myRangeList)
  vlayer.setRenderer(myRenderer)
  
  vlayer.triggerRepaint()
  canvas.show()
  app.exec_()
  saveImage("my-traj.png")
  

  

  Maybe the most powerful option is to use data-defined symbology. For example, to control line width and color:

  renderer = QgsSingleSymbolRenderer(QgsSymbol.defaultSymbol(geom_type))
  
  exp_width = 'scale_linear("speed", 0, 3, 0, 7)'
  exp_color = "coalesce(ramp_color('Viridis',scale_linear(\"speed\", 0, 3, 0, 1)), '#000000')"
  
  # [https:] renderer.symbol().symbolLayer(0).setDataDefinedProperty(
      QgsSymbolLayer.PropertyStrokeWidth, QgsProperty.fromExpression(exp_width))
  renderer.symbol().symbolLayer(0).setDataDefinedProperty(
      QgsSymbolLayer.PropertyStrokeColor, QgsProperty.fromExpression(exp_color))
  renderer.symbol().symbolLayer(0).setDataDefinedProperty(
      QgsSymbolLayer.PropertyCapStyle, QgsProperty.fromExpression("'round'"))
  
  vlayer.setRenderer(renderer)
  
  vlayer.triggerRepaint()
  canvas.show()
  app.exec_()
  saveImage("my-traj.png")

• sur Free and Open Source GIS Ramblings: Exploring a hierarchical graph-based model for mobility data representation and analysis

  Publié: 5 November 2023, 10:17pm CET

  Today’s post is a first quick dive into Neo4J (really just getting my toes wet). It’s based on a publicly available Neo4J dump containing mobility data, ship trajectories to be specific. You can find this data and the setup instructions at:

  Maryam Maslek ELayam, Cyril Ray, & Christophe Claramunt. (2022). A hierarchical graph-based model for mobility data representation and analysis [Data set]. Zenodo. [https:]

  I was made aware of this work since they cited MovingPandas in their paper in Data & Knowledge Engineering: “The implementation combines several open source tools such as Python, MovingPandas library, Uber H3 index, Neo4j graph database management system”

  Once set up, this gives us a database with three hierarchical levels:

  

  Neo4j comes with a nice graphical browser that lets us explore the data. We can switch between levels and click on individual node labels to get a quick preview:

  

  Level 2 is a generalization / aggregation of level 1. Expanding the graph of one of the level 2 nodes shows its connection to level 1. For example, the level 2 port node “Audierne” actually refers to two level 1 nodes:

  

  Every “road” level 1 relationship between ports provide information about the ship, its arrival, departure, travel time, and speed. We can see that this two level 1 ports must be pretty close since travel times are only 5 minutes:

  

  Further expanding one of the port level 1 nodes shows its connection to waypoints of level1:

  

  Switching to level 2, we gain access to nodes of type Traj(ectory). Additionally, the road level 2 relationships represent aggregations of the trajectories, for example, here’s a relationship with only one associated trajectory:

  

  There are also some odd relationships, for example, trajectory 43 has two ends and begins relationships and there are also two road relationships referencing this trajectory (with identical information, only differing in their automatic <id>). I’m not yet sure if that is a feature or a bug:

  

  On level 1, we also have access to ship nodes. They are connected to ports and waypoints. However, exploring them visually is challenging. Things look fine at first:

  

  But after a while, once all relationships have loaded, we have it: the MIGHTY BALL OF YARN ™:

  

  I guess this is the point where it becomes necessary to get accustomed to the query language. And no, it’s not SQL, it is Cypher. For example, selecting a specific trajectory with id 0, looks like this:

   MATCH (t1 {traj_id: 0}) RETURN t1

  

  But more on this another time.

• sur Oslandia: QField 3.0 release : field mapping app, based on QGIS

  Publié: 30 October 2023, 1:03pm CET

  We are very happy and enthusiasts at Oslandia to forward the QField 3.0 release announcement, the new major update of this mobile GIS application based on QGIS.

  Oslandia is a strategic partner of OPENGIS.ch, the company at the heart of QField development, as well as the QFieldCloud associated SaaS offering. We join OPENGIS.ch to announce all the new features of QField 3.0.

  Get QField 3.0 now !

  

   

  Shipped with many new features and built with the latest generation of Qt’s cross-platform framework, this new chapter marks an important milestone for the most powerful open-source field GIS solution.

  Main highlights

  Upon launching this new version of QField, users will be greeted by a revamped recent projects list featuring shiny map canvas thumbnails. While this is one of the most obvious UI improvements, countless interface tweaks and harmonization have occurred. From the refreshed dark theme to the further polishing of countless widgets, QField has never looked and felt better.

  The top search bar has a new functionality that allows users to look for features within the currently active vector layer by matching any of its attributes against a given search term. Users can also refine their searches by specifying a specific attribute. The new functionality can be triggered by typing the ‘f’ prefix in the search bar followed by a string or number to retrieve a list of matching features. When expanding it, a new list of functionalities appears to help users discover all of the tools available within the search bar.

  QField’s tracking has also received some love. A new erroneous distance safeguard setting has been added, which, when enabled, will dictate the tracker not to add a new vertex if the distance between it and the previously added vertex is greater than a user-specified value. This aims at preventing “spikes” of poor position readings during a tracking session. QField is now also capable of resuming a tracking session after being stopped. When resuming, tracking will reuse the last feature used when first starting, allowing sessions interrupted by battery loss or momentary pause to be continued on a single line or polygon geometry.

  On the feature form front, QField has gained support for feature form text widgets, a new read-only type introduced in QGIS 3.30, which allows users to create expression-based text labels within complex feature form configurations. In addition, relationship-related form widgets now allow for zooming to children/parent features within the form itself.

  To enhance digitizing work in the field, QField now makes it possible to turn snapping on and off through a new snapping button on top of the map canvas when in digitizing mode. When a project has enabled advanced snapping, the dashboard’s legend item now showcases snapping badges, allowing users to toggle snapping for individual vector layers.

  In addition, digitizing lines and polygons by using the volume up/down hardware keys on devices such as smartphones is now possible. This can come in handy when digitizing data in harsh conditions where gloves can make it harder to use a touch screen.

  While we had to play favorites in describing some of the new functionalities in QField, we’ve barely touched the surface of this feature-packed release. Other major additions include support for Near-Field Communication (NFC) text tag reading and a new geometry editor’s eraser tool to delete part of lines and polygons as you would with a pencil sketch using an eraser.

  Thanks to Deutsches Archäologisches Institut, Groupements forestiers Québec, Amsa, and Kanton Luzern for sponsoring these enhancements.

  Quality of life improvements

  Starting with this new version, the scale bar overlay will now respect projects’ distance measurement units, allowing for scale bars in imperial and nautical units.

  QField now offers a rendering quality setting which, at the cost of a slightly reduced visual quality, results in faster rendering speeds and lower memory usage. This can be a lifesaver for older devices having difficulty handling large projects and helps save battery life.

  Vector tile layer support has been improved with the automated download of missing fonts and the possibility of toggling label visibility. This pair of changes makes this resolution-independent layer type much more appealing.

  On iOS, layouts are now printed by QField as PDF documents instead of images. While this was the case for other platforms, it only became possible on iOS recently after work done by one of our ninjas in QGIS itself.

  Many thanks to DB Fahrwgdienste for sponsoring stabilization efforts and fixes during this development cycle.

  Qt 6, the latest generation of the cross-platform framework powering QField

  Last but not least, QField 3.0 is now built against Qt 6. This is a significant technological milestone for the project as this means we can fully leverage the latest technological innovations into this cross-platform framework that has been powering QField since day one.

  On top of the new possibilities, QField benefited from years of fixes and improvements, including better integration with Android and iOS platforms. In addition, the positioning framework in Qt 6 has been improved with awareness of the newer GNSS constellations that have emerged over the last decade.

  Forest-themed release names

  Forests are critical in climate regulation, biodiversity preservation, and economic sustainability. Beginning with QField 3.0 “Amazonia” and throughout the 3.X’s life cycle, we will choose forest names to underscore the importance of and advocate for global forest conservation.

  

  Software with service

  OPENGIS.ch and Oslandia provides the full range of services around QField and QGIS : training, consulting, adaptation, specific development and core development, maintenance and assistance. Do not hesitate to contact us and detail your needs, we will be happy to collaborate : infos+qfield@oslandia.com

  As always, we hope you enjoy this new release. Happy field mapping!

  Publié: 26 October 2023, 4:16pm CEST

  As a small and medium business operating in Europe GeoCat BV is clearly affected by the forthcoming European Cyber Resilience Act (CRA).  We are a proud open source company and are concerned about our friends and partners caught up in the uncertainty around this proposed legislation.

  We applaud the goals of the CRA as security is a responsibility GeoCat handles with care on behalf of our customers and products.

  GeoCat is proud of the products we offer our customers: GeoCat Live, GeoNetwork Enterprise and GeoServer Enterprise. Each of these products are offered with a clear vendor relationship, an aspect of which is the handling and communication of security vulnerabilities.

  Part of the magic of free and open-source is the rich collaborations formed across industry, academia, and government working alongside non-governmental organizations and enthusiasts. We are concerned that the CRA as proposed places undue hardships on these relationships. These relationships form a network of trust, and cannot be reduced to a product relationship.

  We encourage regulators to seek expert input at this time. With so much of technology based in free and open-source technology we encourage regulators to look at ways to support security priorities with a deeper understanding.

  Dutch regulators are encouraged to read:

• sur XYCarto: GRASS GIS, Docker, Makefile

  Publié: 25 October 2023, 12:47am CEST

  Small example of using Docker and Makefile to implement GRASS GIS. This blog is written to be complimentary to the Github repository found here. Included in this post is a more verbose explanation of what is happening in the Github repository. Users can explore the scripts to see the underlying bits that make it each step. The intention is to help simplify the GRASS set-up and execution of processes using GRASS operations.

  TL;DR

  GitHub repository is here with the method and documents.

  Summary

  This is a basic example of setting up scripted GRASS process through a Docker image and using a makefile to launch the process. The goal is remove the need to install GRASS on your machine and to fully containerize the process within Docker.

  It is assumed that users have a familiarity with Docker, Make, and GRASS.

  In short, the repo is built to launch a GRASS environment and call a script with the users GRASS commands. Ideally, users should be able to clone the Github repository, build the Docker locally (or pull it), and run a simple make command calling the primary script to perform the GRASS operations.

  Methods in the repository have been tested using Ubuntu and MacOS operating systems.

  Important

  This method is developed for scripting purposes and not intended for saving data in your GRASS environment. Using this method, each time the script is run the initial operation checks to see if a GRASS environment exists. If so, that environment is destroyed and a new environment is built.

  Requirements

  make
  docker
  

  Methods

  If you prefer try out the commands given below, you will need to clone the Git repo:

  git clone git@github.com:xycarto/grass-docker-make.git
  

  These are the two primary commands to set-up the GRASS, Docker, Make operations. Users will first need to build a Docker containing the GRASS installation. Inside the makefile are all the necessary components to find the Dockerfile and build the image. I’ve tagged this build with “xycarto” (see the top of the makefile); however, you can name this whatever you choose.

  Build GRASS Docker

  make docker-local
  

  Run GRASS Script

  With the Docker image in place, you can test if the method is working by checking the GRASS version. This make command uses two scripts. First, a script is called to construct the GRASS environment and then, call the script with all your GRASS operations. The second script is launched using:

  grass grass/GRASS_ENV/PERMANENT --exec bash grass-script.sh
  

  The —exec indicates the script is run within the GRASS environment giving users access to all the GRASS capabilities.

  GRASS needs to run within a designated projection. Included in the make command is a variable to set this. Users can implement any projection here using the EPSG value. The following is building a GRASS environment in New Zealand Transverse Mercator (NZTM), EPSG:2193:

  make grass-project proj="2193"
  

  This should output the GRASS version installed in the Docker.

  Modifications

  Users can implement any GRASS commands and methods in the run-grass.sh script, simply by modifying the file.

  How this can be used

  File variables can be given to the GRASS process back in the make command and passing this through the run-grass.sh script. For example, say you have a example.tif file you’d like to process in GRASS. Users can add a variable to the make file called tif. It might look like this in the makefile:

  grass-project:
  $(RUN) bash run-grass.sh $(proj) $(tif)
  

  The call of the command looks like:

  make grass-project proj=“2193" tif=example.tif
  

  Now with the makefile modified, you need to pass the variable through to the GRASS processing. First you need to modify the run-grass.sh script to accept the new variable from make. This can be done by adding the following line at the top:

  tif=$2
  

  Where $2 means the second argument in the command given. The run-grass.sh script now has the tif path variable. With this, you can now pass the path to the actual GRASS script by modifying the last line like so:

  grass grass/GRASS_ENV/PERMANENT --exec bash grass-script.sh $tif
  

  The grass-script.sh can now be modified to accept the tif variable by adding the following line at the top:

  tif=$1
  

  Once you get this all set up an running, the real power comes now in a scripted method run a large collection of tifs through a GRASS process.

  Let’s say you have 1000 tifs that need to run. You can list these tifs and simply develop a method like the the following:

  cat list-of-tifs.txt | xargs -P 1 -t -I % make grass-project proj=“2193" tif=%
  

  This method would sequentially process the tif list through your GRASS process.

• sur Marco Bernasocchi: QField 3.0 “Amazonia” is here – Feature-packed and super slick.

  Publié: 24 October 2023, 3:20pm CEST

  Pièce jointe: [télécharger]

  We’re so excited and proud of this latest QField version that we’ve opted for a major 3.0 version update.

  Get it now

  Shipped with many new features and built with the latest generation of Qt’s cross-platform framework, this new chapter marks an important milestone for the most powerful open-source field GIS solution.

  Main highlights

  Upon launching this new version of QField, users will be greeted by a revamped recent projects list featuring shiny map canvas thumbnails. While this is one of the most obvious UI improvements, countless interface tweaks and harmonization have occurred. From the refreshed dark theme to the further polishing of countless widgets, QField has never looked and felt better.

  The top search bar has a new functionality that allows users to look for features within the currently active vector layer by matching any of its attributes against a given search term. Users can also refine their searches by specifying a specific attribute. The new functionality can be triggered by typing the ‘f’ prefix in the search bar followed by a string or number to retrieve a list of matching features. When expanding it, a new list of functionalities appears to help users discover all of the tools available within the search bar.

  QField’s tracking has also received some love. A new erroneous distance safeguard setting has been added, which, when enabled, will dictate the tracker not to add a new vertex if the distance between it and the previously added vertex is greater than a user-specified value. This aims at preventing “spikes” of poor position readings during a tracking session. QField is now also capable of resuming a tracking session after being stopped. When resuming, tracking will reuse the last feature used when first starting, allowing sessions interrupted by battery loss or momentary pause to be continued on a single line or polygon geometry.  

  On the feature form front, QField has gained support for feature form text widgets, a new read-only type introduced in QGIS 3.30, which allows users to create expression-based text labels within complex feature form configurations. In addition, relationship-related form widgets now allow for zooming to children/parent features within the form itself.

  To enhance digitizing work in the field, QField now makes it possible to turn snapping on and off through a new snapping button on top of the map canvas when in digitizing mode. When a project has enabled advanced snapping, the dashboard’s legend item now showcases snapping badges, allowing users to toggle snapping for individual vector layers. 

  In addition, digitising lines and polygons by using the volume up/down hardware keys on devices such as smartphones is now possible. This can come in handy when digitizing data in harsh conditions where gloves can make it harder to use a touch screen. 

  While we had to play favourites in describing some of the new functionalities in QField, we’ve barely touched the surface of this feature-packed release. Other major additions include support for Near-Field Communication (NFC) text tag reading and a new geometry editor’s eraser tool to delete part of lines and polygons as you would with a pencil sketch using an eraser.

  Thanks to Deutsches Archäologisches Institut, Groupements forestiers Québec, Amsa, and Kanton Luzern for sponsoring these enhancements. 

  Quality of life improvements

  Starting with this new version, the scale bar overlay will now respect projects’ distance measurement units, allowing for scale bars in imperial and nautical units.

  QField now offers a rendering quality setting which, at the cost of a slightly reduced visual quality, results in faster rendering speeds and lower memory usage. This can be a lifesaver for older devices having difficulty handling large projects and helps save battery life.

  Vector tile layer support has been improved with the automated download of missing fonts and the possibility of toggling label visibility. This pair of changes makes this resolution-independent layer type much more appealing.

  On iOS, layouts are now printed by QField as PDF documents instead of images. While this was the case for other platforms, it only became possible on iOS recently after work done by one of our ninjas in QGIS itself.

  Many thanks to DB Fahrwgdienste for sponsoring stabilization efforts and fixes during this development cycle.

  Qt 6, the latest generation of the cross-platform framework powering QField

  Last but not least, QField 3.0 is now built against Qt 6. This is a significant technological milestone for the project as this means we can fully leverage the latest technological innovations into this cross-platform framework that has been powering QField since day one.

  On top of the new possibilities, QField benefited from years of fixes and improvements, including better integration with Android and iOS platforms. In addition, the positioning framework in Qt 6 has been improved with awareness of the newer GNSS constellations that have emerged over the last decade.

  Forest-themed release names

  Forests are critical in climate regulation, biodiversity preservation, and economic sustainability. Beginning with QField 3.0 “Amazonia” and throughout the 3.X’s life cycle, we will choose forest names to underscore the importance of and advocate for global forest conservation. 

  As always, we hope you enjoy this new release. Happy field mapping!

  Publié: 17 October 2023, 6:58pm CEST

  What’s new in a nutshell

  The GRASS GIS 8.3.0 release provides more than 360 changes compared to the 8.2 branch. This new minor release brings in many fixes and improvements in GRASS GIS modules and the graphical user interface (GUI) which now has the single window layout by default. Some of the most relevant changes include: support for parallelization in three raster modules, new options added to several temporal modules, and substantial clean-up of g.extension, the module that allows the installation of add-ons. The GUI also received a lot of attention with many fixes and items reorganised. We have also adopted the Clang format and indented most of the C code accordingly. A lot of effort was put into cleaning up the C/C++ code to fix almost all compiler warnings.

  Translations have been moved from Transifex to Weblate, which automatically creates pull requests with the translated chunks. We’d like to thank the translators of all languages for their long term support!

  

  Also, docker images have been updated and moved from the mundialis to the OSGeo organization at https://hub.docker.com/r/osgeo/grass-gis/.

  We have carried out quite some work in the GitHub Actions: we added support for “pre-commit” in order to reduce unnecessary runs of the automated checks, there were notable improvements in the code checking section and we have activated renovatebot to automatically maintain GitHub Actions.

  Last but not least, we have significantly improved the automated release creation to reduce maintainer workload and we have gained nine new contributors! Welcome all!!

  We would like to thank our 2023 sponsors North River Geographic Systems Inc and How 2 Map for their financial assistance.

  Keeping GeoServer sustainable requires a long term community commitment. If you were unable to contribute time testing the release candidate, sponsorship options are available via OSGeo.

  Upgrade Notes

  GeoServer strives to maintain backwards compatibility allowing for a smooth upgrade experience.

  We have one minor change to share in this release:

  • URL Checks: The url check security setting is now enabled by default.

    In GeoServer 2.22.5 and 2.23.2 this setting was available for use, but was turned off by default. If you are not yet in a position to upgrade to 2.24.0 you may wish to enable the recommended setting.

  Security Considerations

  This release addresses security vulnerabilities and is considered an essential upgrade for production systems.

  • CVE-2023-43795 WPS Server Side Request Forgery
  • CVE-2023-41339 Unsecured WMS dynamic styling sld=url parameter affords blind unauthenticated SSRF

  See project security policy for more information on how security vulnerabilities are managed.

  IAU authority support and EPSG assumption removal

  The new gs-iau extension module provides support for planetary CRSs, sourced from the International Astronomical Union. This allows users to manage GIS data over the Moon, Mars, or even the Sun, with well known, officially supported codes.

  In addition to that, many bug fixes occurred in the management of CRSs and their text representations (plain codes, URL, URIs) so that the EPSG authority is no longer assumed to be the only possibility, in a variety of places, such as, for example, GML output. The code base has seen this assumption for twenty long years already, and while we made a good effort to eliminate the assumption, it could be still lurking in some places. Please test and let us know.

  GeoServer Printing Extension Updates

  The printing extension has seen big changes - with a host of new functionality developed by GeoSolutions over the years. With this update the printing module can now be used out-of-the-box by GeoNode and MapStore (no more customization required).

  This update covers the release of MapFish Print 2.3.0 (and restores website user-guide).

  GeoServer documentation has been updated with configuration options covering the new functionality.

  • Max number of columns configuration for multi column legends
  • Simple colored box icon in legends
  • Explicit support of GeoServer CQL_FILTER parameter (also with layers merge support): wiki
  • Legend fitting
  • Don’t break legend items
  • Reorder legends block in columns
  • Images content
  • Dynamic images page
  • Multipage legends
  • Custom intervals in ScalebarBlock
  • Clustering Support wiki
  • HTML rendering in text blocks
  • Extra Pages
  • Group Rendering in attribute blocks
  • Skip rendering of pages
  • Automatic X-Forwarded-For
  • Parsing of Base64 encoded images

  Thanks to GeoSolutions for adding functionality to mapfish-print for the GeoNode project. Shout out to Tobia Di Pisa and Giovanni Allegra for integration testing. Jody Garnett (GeoCat) was responsible for updating the mapfish print-lib for Java 11 and gathering up the functionality from different branches and forks. And integrating the updated configuration instructions with the GeoServer User Guide.

  • GEOS-11159 Update mapfish-print-lib 2.3.0

  New Security > URL Checks page

  The previous 2.23 series added a new Check URL facility under the Security menu, but it was turned off by default, for backwards compatibility reasons. This functionality allows administrators to manage OGC Service use of external resources.

  This has been included in GeoServer 2.22.x and 2.23.x series for backwards compatibility.

  Backwards compatibility note:: This functionality is turned ON by default from GeoServer 2.24.0 onwards.

  
  

  For information and examples on how to use the URL Check page, visit user guide documentation.

  Project Updates Updated Security Policy

  This release follows a revised security policy. Our existing “responsible disclosure policy” has been renamed, the practice is now called “coordinated vulnerability disclosure.” Last year we enabled GitHub private vulnerability reporting, we will now use these facilities to issue CVE numbers.

  Coordinated vulnerability disclosure

  Disclosure policy:

  1. The reported vulnerability has been verified by working with the geoserver-security list
  2. GitHub security advisory is used to reserve a CVE number
  3. A fix or documentation clarification is accepted and backported to both the “stable” and “maintenance” branches
  4. A fix is included for the “stable” and “maintenance” downloads (released as scheduled, or issued via emergency update)
  5. The CVE vulnerability is published with mitigation and patch instructions

  This represents a balance between transparency and participation that does not overwhelm participants. Those seeking greater visibility are encouraged to volunteer with the geoserver-security list; or work with one of the commercial support providers who participate on behalf of their customers.

  This change has already resulted in improved interaction with security researchers.

  Thanks to Jody Garnett (GeoCat) for this proposal on behalf of GeoCat Live customers.

  Developer updates Internal refactor to remove “org.opengis” package usage

  The GeoTools project moved away from using the org.opengis package after complaints from OGC GeoAPI working group representatives, using the same package name. Interfaces have been moved to the org.geotool.api package, along with some general clean up.

  While this does not affect GeoServer users directly, it’s of consequence for those that have installations with custom, home grown plugins that might have to be migrated as a consequence. For those, the GeoTools project offers a migration guide, along with a refactoring script that might perform the migration for you, or else, get you close to a working point. GeoServer itself has been migrated using these scripts, with minimal manual intervention.

  For more details, and access to the migration script, please see the GeoTools 30 upgrade guide.

  Thanks to Jody Garnett (GeoCat), Andrea Aime (GeoSolutions), and Ian Turton (ASTUN Technologies) for all the hard work on this activity. We would also like to thank the Open Source Geospatial Foundation for setting up a cross-project activity and financial support to address this requested change.

  Community modules updates

  While not strictly part of this release, it’s interesting to know about some community module advances that can be found only in the the 2.24.x series.

  Two extensions are no longer actively supported and are now available as community modules:

  • GEOS-10960 Downgrade imagemap module to community
  • GEOS-10961 Downgrade xslt extension to community

  The following community modules have been removed (due to lack of interest):

  • GEOS-10962 Remove wms-eo community module
  • GEOS-10963 Remove SAML community module
  • GEOS-10966 Remove importer-fgdb community module
  • GEOS-10967 Remove teradata community module
  • GEOS-10977 Remove wmts-styles community module
  • GEOS-10978 Remove nsg-wmts community module
  • GEOS-10984 Remove ows-simulate community module

  OGC API community modules continues to improve

  The OGC API community module keeps improving. In particular, thanks to the GeoNovum sponsorship, GeoSolutions made the OGC API Features module pass the OGC CITE compliance tests, for the “core” and “CRS by reference” conformance classes. Along with this work, other significant changes occurred:

  • Made the API version number appear in the service path, easing future upgrades
  • Support for configurable links, required to get INSPIRE download service compliance.

  In addition to that, the new “search” experimental conformance class allows to POST complex searches against collections, as a JSON document, in a way similar to the STAC API.

  

  

  Those interested in this work are encouraged to contact Andrea Aime (GeoSolutions).

  • GEOS-10924 Support JSON-FG draft encoding in OGC API - Features
  • GEOS-11045 Implement proposal “OGC API - Features - Part n: Query by IDs”
  • GEOS-10882 Add an option to remove trailing slash match in OGC APIs
  • GEOS-10887 Add angle brackets to OGC API CRS Header
  • GEOS-10892 Allow configuring custom links for OGC API “collections” and single collection resources
  • GEOS-10895 Make OGC API CITE compliant even if the trailing slash is disabled: landing page exception
  • GEOS-11058 Support other CRS authorities in OGC APIs
  • GEOS-10909 Don’t link from OGC API Features to WFS 2.0 DescribeFeatureType output, if WFS is disabled
  • GEOS-10954 Split ogcapi community module package into single functionality packages

  DataDir Catalogue loader

  For folks working with very large catalogues some improvement from cloud native geoserver are now available to reduce startup time.

  Thanks to Gabriel Roldan for folding this improvement into a community module for the rest of the GeoServer community to enjoy.

  GeoServer Access Control List Project

  The GeoServer Access Control List project is an independent application service that manages access rules, and a GeoServer plugin that requests authorization limits on a per-request basis.

  The vector mosaic and FlatGeoBuf modules sport significant performance improvements

  FlatGeoBuf is a “performant binary encoding for geographic data”, a single file format that also manages to be cloud native and include a spatial index. GeoServer provides access to this format thought the WFS FlatGeobuf output format, which not only can write the format, but also read it as a standard data store.

  The Vector Mosaic datastore supports creation of mosaics made of single file vector data, useful in situations where the access to data is targeted to sub-pages of a larger data set (e.g., data for a single time, or a single customer, or a single data collect, out of a very large uniform set of vectors) and the database storage for it has become either too slow, or too expensive.

  These two modules make a great combo for those in need to handle very large vector datasets, by storing the FlatGeoBuf on cheap storage.

  In particular, the FlatGeoBuf module saw speed improvements that made it the new “fastest vector format” for cases where one needs to display a large data set, all at once, on screen (PostGIS remains the king of the hill for anything that needs sophisticated filtering instead).

  For reference, we have timed rendering 4 million tiny polygons out of a precision farming collect, using a 7 classes quantile based SLDs. Here is a tiny excerpt of the map:

  

  And here are the timings to render the full set of polygons, putting them all on screen, at the same time, with a single GetMap request:

  • PostGIS, 113 seconds
  • Shapefile, 41 seconds
  • Flatgeobuf, 36 seconds

  The tuning is not complete, more optimizations are possible. Interested? Andrea Aime is the contact point for this work.

• sur Sean Gillies: Bear 100 recap

  Publié: 7 October 2023, 1:35am CEST

  A week ago I started the Bear 100 Endurance Run. I did not finish. This was my first DNF. I'm still trying to figure out what went wrong and evaluate how I responded.

  To recap: I rolled into the sixth aid station, Tony Grove, mile 51, at 9:59 p.m. I made a head to toe gear change. Underwear, pants, hat, socks, and shoes. Diaper ointment lube on my feet and privates. Ate potatoes and chicken noodle soup and refilled my bottles. I spent too much time there, but this was going to be my main stop before dawn, and I wanted to get properly set up for 8 hours of plugging through the night. I left at 10:43 p.m.

  Somewhere around mile 59, descending into Franklin Basin, my left ankle stopped working, and I limped into the Franklin Basin aid station (mile 62). After 15 minutes of triage, I decided to quit. I had no flexibility or stability in my left foot, and continuing seemed pointless.

  What happened? I couldn't remember a single major incident. I'd had a number of little wobbles earlier in the day and the descent from Tony Grove was pretty rough. I certainly picked up a little damage along the way. And I'd sprained this ankle four weeks ago. Maybe it wasn't strong enough to go 100 miles. It's possible that I fell asleep on my feet at 1:30 a.m. and rolled it. I was certainly sleepy enough at some points. Either the accumulation of stress was too much for my ankle, or an acute injury happened while I was checked out. Or both. I don't know for sure.

  I'm disappointed. Otherwise, things were going well. My gear choices were solid. I was eating and drinking well enough. Other than one toenail lost to kicking a rock, my feet were fine, no hotspots or blisters. My ankle was swollen for several days, but I didn't go far enough to wreck my quads or hips. Sigh.

  I will try this again.

  More about the race, photos, stories, etc, soon.

• sur QGIS Blog: Call for Proposals: QGIS Website Overhaul 2023/2024

  Publié: 3 October 2023, 6:45pm CEST

  Background

  Our web site ( [https:]] ) dates back to 2013, it is time for a revision!

  As well as modernizing the look and feel of the site, we want the content to be updated to represent changes in the maturity of the project.

  We want to appeal to new audiences, especially business and NGO decision makers (in particular the experience for the front pages), whilst still maintaining appeal to grass roots users (especially the lower level pages which contain many technical details and community collaboration notes).

  We want to enhance our fund raising efforts through a site that encourages people to contribute to, as well as take from, the project.

  Existing effort

  First some key links:

  • Current web site: [https:]
  • Design for new web site landing page: [https:]]
  • Design for new web site (figma): [https:]]  
  • Code for new web site (what we have built so far): [https:]]
  • Plugins web site: [https:]]
  • QGIS Documentation Site: [https:]]  
  • QGIS User Manual: [https:]]
  • QGIS Server Manual: [https:]]
  • Gentle Introduction to GIS: [https:]]
  • QGIS Python Cookbook: [https:]]
  • QGIS C++  API Documentation: [https:]]
  • QGIS Python API Documentation: [https:]]
  • QGIS Certification and Changelog: [https:]]

  The above websites were created with a mix of technologies:

  • Sphinx (rst)
  • Doxygen
  • Custom Django Apps

  It will not be possible to unify the technology used for all of the above sites, but we want all of the web sites to have a cohesive appearance and the navigation flow between them to be seamless. For the main website at [https:]] and its child pages, we want to re-implement the site to provide a new experience – according to the design we have laid out in our figma board. Note that we want to follow this design. Some small tweaks will be fine but we are not looking for a ‘from scratch’ re-implementation of our design.

  

  This will be our website for the next 10 years – you need to hand it over to us in a way that we can continue working on it and maintaining it without your intervention.

  We are calling for proposals to help us with this migration as per the phases described below.

  Phase 1?: Project planning

  • Timeline
  • Proposed site structure
    • What content will be kept
    • What will be removed
    • What is new to be added
  • Keep front page as starting point
    • Suggest tweaks if needed
  • Establish a clear vocabulary of page types
    • Second and third level page design
    • Special pages such as
      • Download
      • Release countdown
      • Donation / sustaining members
      • Gallery
      • and any other you identify as non-standard second/third level
  • Guidance and standards for producing visuals like screenshots etc. For example, how we present QGIS screenshots in a flattering way.
  • Establish a plan for auxiliary sites:
    • Plugins.qgis.org
    • Api.qgis.org
    • Docs.qgis.org
    • etc. (see intro for more exhaustive list)
  • Iterative review and feedback from the QGIS web team should be incorporated from biweekly check in calls.

  Outcome: We have a clear roadmap and design guide for migrating all of our websites to a consistent unified experience.

  Phase 2?: Content migration of the main site

  During this phase the contractor will focus on migrating the content of the main site to the new platform.

  There will be an iterative review and feedback from the QGIS web team should be incorporated from biweekly check-in calls.

  Outcome: [https:]] new site goes live! (Target date end of February 2024)

  Phase 3?: Auxiliary sites migrations

  This is out of scope of the current call for proposals but should be part of the overall planning process:

  This would be a collaborative process involving a QGIS funded web developer and the consultant. 

  Iterative review and feedback from the QGIS web team should be incorporated from biweekly check in calls.

  Outcome: Auxiliary sites goes live with a cohesive look and feel to match the main site.

  What we will provide

  • Maps and screenshots, videos, animations (with inputs from design team)
  • Inputs in terms of content review

  Qualification criteria

  Must have an established track record of website design and content creation.

  Individuals or companies equally welcome to apply.

  Any potential conflict of interest should be declared in your application.

  Discussions will happen in English, with live discussions as well as written communication via issues or Pull request. Being reasonably fluent in English and understand the soft skills required to interact in a community project will be more than appreciated

  Payment milestones

  10 % Kick off

  40 % Phase 1 Completion

  50 % Phase 2 Completion

  Indicative budget

  We would like to point you to the QGIS Annual Budget so that you have a sense of our broad financial means (i.e. we will not be able to afford proposals in excess of €25,000 for phase 1+2).

  [https:]]

  Technology choices and IP:

  • Must be wholly based on Open Source tooling (e.g. javascript, css, web frameworks)
  • Needs to be ideally implemented in Hugo (or Sphinx)
  • Must produce a static web site (except for existing django based sites)
  • Publication and development workflow will follow standard pull request / review process via our GitHub repositories
  • Mobile friendly
  • Site will be english only – any auto-translation tooling that can be added so that users can trivially see an auto-translated version of the site will be considered favourably.

  Proposal submission

  Your proposal should consist of no more than 5 pages (include links to relevant annexes if needed) covering the following:

  • Overview of yourself / your organization
  • Delivery timeline
  • Team composition
  • Budget for each phase
  • Examples of prior work
  • Bonus things to mention if relevant: GIS experience & working with Open Source projects

  Please send your proposal to finance@qgis.org by October 29nd 2023 midnight, anywhere on earth.

  A versão 2.24.x do GeoServer traz entre suas novidades as verificações de acesso externo de URL que permite controlar as verificações executadas em URLs fornecidas pelo usuário que o GeoServer usará para acessar recursos remotos.

  Atualmente, as verificações são realizadas nas seguintes funcionalidades:

  • Solicitações WMS GetMap, GetFeatureInfo e GetLegendGraphic com folhas de estilo SLD remotas (parâmetro SLD)
  • Ícones remotos referenciados por estilos (o acesso aos ícones no diretório de dados é sempre permitido)
  • Solicitações WMS GetMap e GetFeatureInfo no modo de representação de recursos (parâmetros REMOTE_OWS e REMOTE_OWS_TYPE)
  • Entradas remotas WPS, como solicitações GET ou POST

  Para criar as regras de verificação, o GeoServer utiliza expressões regulares. Na internet existem sites disponíveis que irão te ajudar a definir um padrão de expressão regular Java (linguagem que o GeoServer é desenvolvido) válido. Essas ferramentas podem ser usadas para interpretar, explicar e testar expressões regulares. Por exemplo:

  – [https:]] (habilitar o tipo Java 8)

  – [https:]]

  1. Configuração de verificações de URL

  Navegue até a página Dados > Verificações de URL para gerenciar e configurar verificações de URL.

  

  Tabela de verificações de URL

  Use as opções Ativar/Desativar para habilitar este recurso de segurança:

  • Quando a caixa de seleção de verificações de URL está habilitada, as verificações de URL são realizadas para limitar o acesso do GeoServer a recursos remotos, conforme descrito acima. A ativação de verificações de URL é recomendada para limitar a interação normal dos protocolos Open Web Service usados ??para ataques de Cross Site Scripting.
  • Quando a caixa de seleção está desabilitada, as verificações de URL NÃO são habilitadas, o GeoServer recebe acesso irrestrito a recursos remotos. Desativar verificações de URL não é uma configuração segura ou recomendada.

  2. Adicionando uma verificação baseada em expressão regular

  Os botões para adicionar e remover verificações de URL podem ser encontrados na parte superior da lista de verificação de URL.

  Para adicionar uma verificação de URL, pressione o botão Adicionar nova verificação. Você será solicitado a inserir os detalhes da verificação de URL (conforme descrito abaixo em Editando uma verificação).

  3. Removendo uma verificação

  Para remover uma verificação de URL, marque a caixa de seleção ao lado de uma ou mais linhas na lista de verificação de URL. Pressione o botão Remover verificações de URL selecionadas para remover. Você será solicitado a confirmar ou cancelar a remoção. Pressionar OK para remover as verificações de URL selecionadas.

  4. Editando uma verificação

  As verificações de URL podem ser configuradas, com os seguintes parâmetros para cada verificação:

  • Nome: Nome da verificação, utilizado para identificá-lo na lista.
  • Descrição: Descrição da verificação, para referência posterior.
  • Expressão regular: Expressão regular usada para corresponder aos URLs permitidos
  • Habilitado: Caixa de seleção para ativar ou desativar a verificação

  Veja abaixo como é a tela de configuração:

  

  Tela de configuração de verificação de URL

  5. Testando verificações

  O formulário Testar verificações permite que uma URL seja verificada, informando se o acesso é permitido ou não.

  Pressione o botão Testar URL para realizar as suas verificações. Se pelo menos uma verificação corresponder ao URL, ele será permitido e o teste indicará a verificação que permite o acesso. Caso contrário, será rejeitado e o teste indicará que nenhuma verificação de URL foi correspondente.

• sur Fernando Quadro: GeoServer ACL

  Publié: 27 September 2023, 9:20pm CEST

  A versão 2.24.x do GeoServer traz entre suas novidades o GeoServer ACL (Access Control List), um sistema de autorização avançado.

  Ele consiste em um serviço independente que gerencia regras de acesso e um plugin do GeoServer que solicita limites de autorização por solicitação.

  Como administrador, você usará o GeoServer ACL para definir regras que concedem ou negam acesso a recursos publicados com base nas propriedades da solicitação de serviço, como credenciais do usuário, o tipo de serviço OWS (OGC Web Services) e as camadas solicitadas.

  Essas regras podem ser tão abertas quanto conceder ou negar acesso a espaços de trabalho inteiros do GeoServer, ou tão granulares quanto especificar quais áreas geográficas e atributos de camada permitir que um usuário ou grupo de usuários específico veja.

  Como usuário, você executará solicitações ao GeoServer, como WMS GetMap ou WFS GetFeatures, e o mecanismo de autorização baseado no ACL limitará a visibilidade dos recursos e conteúdos das respostas àqueles que correspondem às regras que se aplicam às propriedades da solicitação e as credenciais do usuário autenticado.

  GeoServer ACL não é um provedor de autenticação. É um gerenciador de autorização que usará as credenciais do usuário autenticado, sejam elas provenientes de HTTP básico, OAuth2/OpenID Connect ou qualquer mecanismo de autenticação que o GeoServer esteja usando, para resolver as regras de acesso que se aplicam a cada solicitação específica.

  GeoServer ACL é Open Source, nascido como um fork do GeoFence. Como tal, segue a mesma lógica para definir regras de acesso a dados e acesso administrativo. Portanto, se você estiver familiarizado com o GeoFence, será fácil raciocinar como o GeoServer ACL funciona.

• sur KAN T&IT Blog: Análisis de calidad de información geoespacial. BID Perú.

  Publié: 25 September 2023, 9:21pm CEST

  En el marco del convenio con el Banco Interamericano de Desarrollo sede Perú (BID Perú), se llevó a cabo el proyecto de análisis de calidad de información geoespacial generados en el contexto del programa “Apoyo a la Plataforma Nacional de Ciudades Sostenibles y Cambio Climático en Lima” para el Ministerio de Ambiente de la República de Perú (MINAM). Este proyecto consistió en realizar el control de calidad de más de 400 capas de información geoespacial en función de los requerimientos establecidos en la familia de normas ISO 19100 que apuntan a regular y a normalizar la generación de información geoespacial con el objetivo de garantizar su interoperabilidad. El objetivo final de este trabajo fue aportar al proceso de mejora de la calidad e interoperabilidad de los datos al Plan Nacional de Adaptación al Cambio Climático (NAP, por sus siglas en inglés) en Perú. 

  El NAP consiste en un exhaustivo documento en donde se plasman los principales lineamientos para planificar la implementación de medidas diseñadas específicamente para reducir los riesgos derivados del impacto del cambio climático. A su vez, este documento pretende ser una fuente de información disponible para la toma de decisiones a nivel gubernamental en torno a ésta problemática. En este sentido, entre los objetivos que persigue el NAP, se presentan los siguientes: 

  1: Integrar y articular diversos instrumentos de gestión: Estrategia Regional de Cambio Climático, NDC y Planes Locales de Adaptación al Cambio Climático.  

  2: Desarrollar un análisis de riesgos climáticos a nivel nacional y regional para 5 áreas temáticas: Agua, Bosques, Agricultura, Pesca y Acuicultura y Salud; y para 4 amenazas clave: movimientos en masa, inundaciones, cambio en las condiciones de aridez y retroceso glaciar.

  3: Actualizar las medidas de adaptación establecidas en cada uno de los instrumentos de gestión, de acuerdo con las necesidades de las poblaciones y los ecosistemas.

  Para llevar a cabo el proceso de revisión y control de calidad de la información generada en este contexto, se trabajó en conjunto con las empresas productoras de la información geoespacial y en constante comunicación con representantes del BID Perú. Estas empresas habían sido convocadas por el Ministerio de Ambiente de Perú en convenio con BID y la organización World Wide Fund for Nature (WWF) con el objetivo de analizar y generar información para: el “Plan de Adaptación Costera para el Área Metropolitana de Lima (AML)”, los “Estudios base sobre riesgo de desastres por riesgos naturales y crecimiento urbano en el AML” y los “Estudios de análisis urbanístico, prefactibilidad y diseños constructivos para acciones estratégicas de accesibilidad, multimodalidad y desarrollo orientado al transporte en el Sistema Integrado de Transporte (SIT) de Lima y Callao”. Toda la información geoespacial generada en el marco de estos tres productos fue el objeto de análisis de la consultoría realizada por Kan.  

  La premisa que guió el desarrollo de este proyecto fue alcanzar un nivel de calidad del dato óptimo que permitiera a los organismos disponibilizar la información producida garantizando el libre acceso, la interoperabilidad, la confiabilidad y la calidad. 

  En primera instancia se presentaron requisitos para la presentación de la información para asegurar el libre acceso. En este sentido, se solicitó que la información pudiera ser consultada a través de software libres, para que pudieran ser consumidos sin necesidad de pagar una licencia para hacerlo, siendo el formato “geopackage” el indicado para cumplir esta condición. 

  El análisis de la información se basó en una metodología específica desarrollada por el equipo SIG de Kan, fundamentada en las normas 19115-3, 19139, 19110 y 19157 que hacen referencia a los formatos e implementación de metadatos, a la catalogación de objetos geográficos y a la calidad del dato, respectivamente. Todo el contenido de estas normas se plasmaron en matrices analíticas que luego fueron aplicadas a cada una de las capas de información. Estas matrices permitieron relevar el estado de la información en relación a: la completud de sus metadatos, formatos de interoperabilidad de la información, calidad del dato, referencias sobre su linaje, uso y propósito, su consistencia lógica y topológica, el análisis de sus atributos, entre otros puntos. En total, se establecieron seis categorías de análisis: 

  A: Compatibilidad del conjunto de datos

  B: Interoperabilidad del conjunto de datos

  C: Interoperabilidad conjunto de metadatos

  D: Interoperabilidad – Metadatos de la capa

  E: Compatibilidad de la capa

  F: Calidad del dato

  Para cada categoría se definieron una serie de elementos de análisis que en total suman 47 ítems. El objetivo final de esta revisión fue cuantificar la usabilidad de la información geográfica producida, estableciendo un rango de usabilidad. Este rango va entre -1 y 1, siendo los valores cercanos a -1 aquellos que incumplen en más de un 50% los elementos establecidos para el análisis y los valores cercanos a 1 aquellos que cumplen en más de un 50% los elementos. De esta forma se obtuvo un resultado parcial de usabilidad por capa y un resultado global de usabilidad para el conjunto de datos. Luego de haber realizado el análisis, se confrontaron los resultados obtenidos con lo establecido por las normas, de esta manera se creó un documento de recomendaciones y sugerencias para la mejora de la calidad e interoperabilidad del dato. 

  Este proyecto permitió conocer la calidad de la información generada en el proyecto e identificar aquellos aspectos posibles de mejorar para garantizar la interoperabilidad de la información. Luego de este proceso de análisis, las empresas aplicaron las recomendaciones y sugerencias realizadas por el equipo SIG de Kan con el que alcanzaron un nivel óptimo de calidad del dato.

  

• sur GeoServer Team: GeoServer 2.24-RC Release

  Publié: 25 September 2023, 2:00am CEST

  GeoServer 2.24-RC release is now available with downloads (bin, war, windows), along with docs and extensions.

  This is a release candidate intended for public review and feedback, made in conjunction with GeoTools 30-RC, GeoWebCache 1.24-RC, mapfish-print-v2 2.3-RC and geofence-3.7-RC.

  Thanks to Andrea Aime (GeoSolutions) and Jody Garnett (GeoCat) for working on making this release candidate.

  Release candidate public testing and feedback

  Testing and providing feedback on releases is part of the open-source social contract. The development team (and their employers and customers) are responsible for sharing this great technology with you.

  The collaborative part of open-source happens now - we ask you to test this release candidate in your environment and with your data. Try out the new features, double check if the documentation makes sense, and most importantly let us know!

  If you spot something that is incorrect or not working do not assume it is obvious and we will notice. We request and depend on your email and bug reports at this time. If you are working with commercial support your provider is expected to participate on your behalf.

  Keeping GeoServer sustainable requires a long term community commitment. If you are unable to contribute time, sponsorship options are available via OSGeo.

  IAU authority support and EPSG assumption removal

  The new gs-iau extension module provides support for planetary CRSs, sourced from the International Astronomical Union. This allows to manage GIS data over the Moon, Mars, or even the Sun, with well known, officially supported codes.

  In addition to that, many bug fixes occurred in the management of CRSs and their text representations (plain codes, URL, URIs) so that the EPSG authority is no longer assumed to be the only possibility, in a variety of places, such as, for example, GML output. The code base has seen this assumption for twenty years long, and while we made a good effort to eliminate the assumption, it could be still lurking in some places. Please test and let us know.

  

  

  To learn more about this extension please visit the user-guide documentation. Thanks to Andrea Aime (GeoSolutions) for working on this activity.

  Developer updates Internal refactor to remove “org.opengis” package usage

  The GeoTools project moved away from using the “org.opengis” package after complaints from OGC GeoAPI working group representatives, using the same package name. Interfaces have been moved to the “org.geotool.api” package, along with some general clean up.

  While this does not affect GeoServer users directly, it’s of consequence for those that have installation with custom, home grown plugins that might have to be migrated as a consequence. For those, the GeoTools project offers a migration guide, along with a refactoring script that might perform the migration for you, or else, get you close to a working point. GeoServer itself has been migrated using these scripts, with minimal manual intervention.

  For more details, and access to the migration script, please see the GeoTools 30 upgrade guide.

  Thanks to Jody Garnett (GeoCat), Andrea Aime (GeoSolutions), and Ian Turton (ASTUN Technologies) for all the hard work on this activity. We would also like to thank the Open Source Geospatial Foundation for setting up a cross-project activity and financial support to address this requested change.

  • GEOS-11070 Upgrading to GeoTools 30.x series, refactor to org.geotools.api interfaces

  Community modules updates

  While not strictly part of this release, it’s interesting to know about some community module advances that can be found only in the the 2.24.x series.

  Two extensions are no longer actively supported and are now available as community modules:

  • GEOS-10960 Downgrade imagemap module to community
  • GEOS-10961 Downgrade xslt extension to community

  The following community modules have been removed (due to lack of interest):

  • GEOS-10962 Remove wms-eo community module
  • GEOS-10963 Remove SAML community module
  • GEOS-10966 Remove importer-fgdb community module
  • GEOS-10967 Remove teradata community module
  • GEOS-10977 Remove wmts-styles community module
  • GEOS-10978 Remove nsg-wmts community module
  • GEOS-10984 Remove ows-simulate community module

  OGC API community modules continues to improve

  The OGC API community module keeps improving. In particular, thanks to the GeoNovum sponsorship, GeoSolutions made the OGC API Features module pass the OGC CITE compliance tests, for the “core” and “CRS by reference” conformance classes. Along with this work, other significant changes occurred:

  • Made the API version number appear in the service path, easing future upgrades
  • Support for configurable links, required to get INSPIRE download service compliance.

  In addition to that, the new “search” experimental conformance class allows to POST complex searches against collections, as a JSON document, in a way similar to the STAC API.

  

  

  Those interested in this work are encouraged to contact Andrea Aime (GeoSolutions).

  • GEOS-10924 Support JSON-FG draft encoding in OGC API - Features
  • GEOS-11045 Implement proposal “OGC API - Features - Part n: Query by IDs”
  • GEOS-10882 Add an option to remove trailing slash match in OGC APIs

  • GEOS-10892 Allow configuring custom links for OGC API “collections” and single collection resources
  • GEOS-10895 Make OGC API CITE compliant even if the trailing slash is disabled: landing page exception
  • GEOS-11058 Support other CRS authorities in OGC APIs
  • GEOS-10909 Don’t link from OGC API Features to WFS 2.0 DescribeFeatureType output, if WFS is disabled
  • GEOS-10954 Split ogcapi community module package into single functionality packages

  DataDir Catalogue loader

  For folks working with very large catalogues some improvement from cloud native geoserver are now available to reduce startup time.

  Thanks to Gabriel Roldan for folding this improvement into a community module for the rest of the GeoServer community to enjoy.

  • GEOS-11049 Community module “datadir catalog loader”

  GeoServer Access Control List Project

  The GeoServer Access Control List project is an independent application service that manages access rules, and a GeoServer plugin that requests authorization limits on a per-request basis.

  The vector mosaic and FlatGeoBuf modules sport significant performance improvements

  FlatGeoBuf is a “A performant binary encoding for geographic data”, a single file format that also manages to be cloud native and include a spatial index. GeoServer provides access to this format thought the WFS FlatGeobuf output format, which not only can write the format, but also read it as a standard data store.

  The Vector Mosaic datastore supports creation of mosaics made of single file vector data, useful in situations where the access to data is targeted to sub-pages of a larger data set (e.g., data for a single time, or a single customer, or a single data collect, out of a very large uniform set of vectors) and the database storage for it is become either too slow, or too expensive.

  These two modules make a great combo for those in need to handle very large vector datasets, by storing the FlatGeoBuf on cheap storage.

  In particular, the FlatGeoBuf module saw speed improvements that made it the new “fastest vector format” for cases where one needs to display a large data set, all at once, on screen (PostGIS remains the king of the hill for anything that needs sophisticated filtering instead).

  For reference, we have timed rendering 4 million tiny polygons out of a precision farming collect, using a 7 classes quantile based SLDs. Here is a tiny excerpt of the map:

  

  And here are the timings to render the full set of polygons, putting them all on screen, at the same time, with a single GetMap request:

  • PostGIS, 113 seconds
  • Shapefile, 41 seconds
  • Flatgeobuf, 36 seconds

  The tuning is not complete, more optimizations are possible. Interested? Andrea Aime is the contact point for this work.

• sur Sean Gillies: Bear 100 race week

  Publié: 24 September 2023, 11:06pm CEST

  This is it, race week. Wednesday I'm flying to Salt Lake City and driving to Logan. Friday before dawn I'm headed up the trail to Bear Lake.

  Week ~5 was a rest week at the end of a big training block. I biked and ran for less than 4 hours. Week ~4 I ran for 12 hours, 53 miles, and 8,500 feet of elevation gain. Much of that was above 10,000 feet in Rocky Mountain National Park, my go-to for accessible high country. I ran up to Granite Pass, 12,100 feet, just below the Longs Peak boulder field, and test drove the gels that will be served at the Bear 100. Spring Energy's Awesome Sauce is good! I could eat them all day. Spring's Speednut product is a bit harder for me to stomach. One of those every few hours might be all I can take.

  At the end of week ~4 I did some volunteering at the Black Squirrel Trail Half-Marathon, a race I've run several times. I helped park cars in the pre-race darkness and get first-timers pointed toward registration and the starting line. I saw the Milky Way in the clear, dark early morning sky. I caught up with the race directors, Nick and Brad, and saw other friends in the first mile of the course. Volunteering at events is always needed and fun. I recommend it.

  In week ~3, I ran for 9.5 hours, 42 miles, and 5,700 feet. In the interest of fine tuning, I went out in the heat of the day and took my poles. In week ~2, last week, I got the new COVID vaccination and did less running and more yoga and body-weight strength and mobility exercise. Split squats with dumbbells made me sore, but I am over it now.

  Where am I at now, in week ~1? I think I have enough experience and adequate training this year to finish. Three events of 40 miles, including one overnight, and one at very high elevation. The heart palpitations that were troubling me last year almost never occur now. I'm well over my most recent sinus infection. I've got all the gear I need and am physically and psychologically prepared for hot weather, cold weather, and rain or snow. The race will have more food than I can eat along the way and will deliver my five drop bags to aid stations and the finish line. I don't have a crew or pacer for the run, but think I'll be fine without. Reality is that it's harder to have these as you get older. Your family is busy and your friends are busy with their own families. I'm shy, but not shy about forming small ad-hoc teams on the trail, so I expect to be fine on that front.

  The Bear 100 Endurance Run starts with 5,000 feet of climbing in the first 10 miles. I can do this. At least it's at the beginning and not the end. That leaves only 17,000 feet for the last 90 miles. I'm joking about this to keep my spirits up. This will be super hard, a big bump up from my hardest week of training, and I'll need to go even deeper into the unknown than I've done at the Never Summer 100K. I'm ready to see what happens out there.

  The one thing that's concerning me is that I have a persistent ache in my right foot. Yesterday I went out for an hour in my Nike Terra Kiger's to see if I might want to bring them along as a shoe option. The answer is no: they don't have enough padding for my foot in its current condition. I feel worse today than yesterday. There's at least a small chance that I have a bone stress problem. The pain and swelling is right on the "N-spot". I'm not going to let this stop me from starting and will see how it goes on Friday. I've got a pretty high pain threshold and will be stashing some ibuprofen in my later drop bags. Cold rain and cold, numb feet, if the forecast holds, might help, too. How is that for positive thinking?

  If you want to follow along on Friday and Saturday, the live tracking should be at [https:]] . My bib number is 314. That website currently shows last year's race. I expect that this year's progress will be shown on Friday morning.

• sur geomatico: HOT-OSM para el seísmo de Marruecos

  Publié: 14 September 2023, 11:18am CEST

  Geomatico dedica un día al mes a colaborar en aquellos proyectos que más nos llaman la atención tecnológica o socialmente. Es lo que llamamos el día del imasdé (I+D), que empieza con todos los trabajadores votando a qué dedicaremos las siguientes horas de trabajo.

  Votaciones poco tecnológicas para decidir el día del I+D

  Como no podía ser de otra manera, esta jornada del 13 de septiembre la dedicamos al precioso proyecto HOT-OSM (Humanitarian OpenStreetMap Team) que había hecho un llamamiento urgente para ayudar a mapear las zonas afectadas por el dramático terremoto del sur de Marruecos.

  Primero hicimos una pequeña introducción a OpenStreetMap (OSM) para profanos para aquella parte del equipo que no tenía experiencia anterior con el proyecto. Vimos los diferentes editores, iD, JOSM y estudiamos un poco las primitivas geométricas que caracterizan el proyecto y por supuesto las Map Features. Ya en HOT, decidimos en que proyecto íbamos a colaborar y nos pusimos a ello.

  Seleccionando zona de trabajo en HOT-OSM

  Había que que cartografiar los edificios dentro de las rejillas que seleccionábamos. En el mismo proyecto de HOT, se explicaba claramente como realizar la tarea a partir de JOSM. Así, mediante el plugin de crear edificios, pudimos aportar nuestro granito de arena a la zona.

  Puede ser complejo definir distinguir exactamente los contornos de los edificios en Marruecos

  Fue muy gratificante, tanto por la tarea, como por la dinámica del trabajo, el compartir una jornada completa con las compañeras realizando un trabajo “sencillo“ en el que a la vez podíamos estar comentando otros aspectos de nuestro día a día. ¡Viva el día del imasdé y HOT-OSM!

  Paul Ramsey and I recently had a Fireside chat with Path to Cituscon. Checkout the Podcast Why People care about PostGIS and Postgres. There were a surprising number of funny moments and very insightful stuff.

  It was a great fireside chat but without the fireplace. We covered the birth and progression of PostGIS for the past 20 years and the trajectory with PostgreSQL. We also learned of Paul's plans to revolutionize PostGIS which was new to me. We covered many other side-line topics, like QGIS whose birth was inspired by PostGIS. We covered pgRouting and mobilitydb which are two other PostgreSQL extension projects that extend PostGIS.

  We also managed to fall into the Large Language Model conversation of which Paul and I are on different sides of the fence on.

• sur Marco Bernasocchi: Analyzing and visualizing large-scale fire events using QGIS processing with ST-DBSCAN

  Publié: 5 September 2023, 10:04am CEST

  A while back, one of our ninjas added a new algorithm in QGIS’ processing toolbox named ST-DBSCAN Clustering, short for spatio temporal density-based spatial clustering of applications with noise. The algorithm regroups features falling within a user-defined maximum distance and time duration values.

  This post will walk you through one practical use for the algorithm: large-scale fire event analysis and visualization through remote-sensed fire detection. More specifically, we will be looking into one of the larger fire events which occurred in Canada’s Quebec province in June 2023.

  Fetching and preparing FIRMS data

  NASA’s Fire Information for Resource Management System (FIRMS) offers a fantastic worldwide archive of all fire detected through three spaceborne sources: MODIS C6.1 with a resolution of roughly 1 kilometer as well as VIIRS S-NPP and VIIRS NOAA-20 with a resolution of 375 meters. Each detected fire is represented by a point that sits at the center of the source’s resolution grid.

  Each source will cover the whole world several times per day. Since detection is impacted by atmospheric conditions, a given pass by one source might not be able to register an ongoing fire event. It’s therefore advisable to rely on more than one source.

  To look into our fire event, we have chosen the two fire detection sources with higher resolution – VIIRS S-NPP and VIIRS NOAA-20 – covering the whole month of June 2023. The datasets were downloaded from FIRMS’ archive download page.

  After downloading the two separate datasets, we combined them into one merged geopackage dataset using QGIS processing toolbox’s Merge Vector Layers algorithm. The merged dataset will be used to conduct the clustering analysis.

  

  In addition, we will use QGIS’s field calculator to create a new Date & Time field named ACQ_DATE_TIME using the following expression:

  to_datetime("ACQ_DATE" || "ACQ_TIME", 'yyyy-MM-ddhhmm')

  This will allow us to calculate precise time differences between two dates.

  Modeling and running the analysis

  The large-scale fire event analysis requires running two distinct algorithms:

  • a spatiotemporal clustering of points to regroup fires into a series of events confined in space and time; and
  • an aggregation of the points within the identified clusters to provide additional information such as the beginning and end date of regrouped events.

  This can be achieved through QGIS’ modeler to sequentially execute the ST-DBSCAN Clustering algorithm as well as the Aggregate algorithm against the output of the first algorithm.

  

  The above-pictured model outputs two datasets. The first dataset contains single-part points of detected fires with attributes from the original VIIRS products as well as a pair of new attributes: the CLUSTER_ID provides a unique cluster identifier for each point, and the CLUSTER_SIZE represents the sum of points forming each unique cluster. The second dataset contains multi-part points clusters representing fire events with four attributes: CLUSTER_ID and CLUSTER_SIZE which were discussed above as well as DATE_START and DATE_END to identify the beginning and end time of a fire event.

  In our specific example, we will run the model using the merged dataset we created above as the “fire points layer” and select ACQ_DATE_TIME as the “date field”. The outputs will be saved as separate layers within a geopackage file.

  Note that the maximum distance (0.025 degrees) and duration (72 hours) settings to form clusters have been set in the model itself. This can be tweaked by editing the model.

  Visualizing a specific fire event progression on a map

  Once the model has provided its outputs, we are ready to start visualizing a fire event on a map. In this practical example, we will focus on detected fires around latitude 53.0960 and longitude -75.3395.

  Using the multi-part points dataset, we can identify two clustered events (CLUSTER_ID 109 and 1285) within the month of June 2023. To help map canvas refresh responsiveness, we can filter both of our output layers to only show features with those two cluster identifiers using the following SQL syntax: CLUSTER_ID IN (109, 1285).

  To show the progression of the fire event over time, we can use a data-defined property to graduate the marker fill of the single-part points dataset along a color ramp. To do so, open the layer’s styling panel, select the simple marker symbol layer, click on the data-defined property button next to the fill color and pick the Assistant menu item.

  In the assistant panel, set the source expression to the following: day(age(to_date('2023-07-01'),”ACQ_DATE_TIME”)). This will give us the number of days between a given point and an arbitrary reference date (2023-07-01 here). Set the values range from 0 to 30 and pick a color ramp of your choice.

  

  When applying this style, the resulting map will provide a visual representation of the spread of the fire event over time.

  Having identified a fire event via clustering easily allows for identification of the “starting point” of a fire by searching for the earliest fire detected amongst the thousands of points. This crucial bit of analysis can help better understand the cause of the fire, and alongside the color grading of neighboring points, its directionality as it expanded over time. Analyzing a fire event through histogram

  Through QGIS’ DataPlotly plugin, it is possible to create an histogram of fire events. After installing the plugin, we can open the DataPlotly panel and configure our histogram.

  Set the plot type to histogram and pick the model’s single-part points dataset as the layer to gather data from. Make sure that the layer has been filtered to only show a single fire event. Then, set the X field to the following layer attribute: “ACQ_DATE”.

  You can then hit the Create Plot button, go grab a coffee, and enjoy the resulting histogram which will appear after a minute or so.

  

  While not perfect, an histogram can quickly provide a good sense of a fire event’s “peak” over a period of time.

  The third week of my season's big training block was my biggest yet from the climbing perspective. My runs averaged 220 feet of elevation gain (D+) per mile, which is what the Bear 100 course will demand of me in 5 weeks. Here are last week's numbers.

  • 20 hours, 37 minutes

  • 76.2 miles

  • 16,775 feet D+

  Extrapolating that to 100 miles, naively, predicts a 28 hour finish. That would be amazing! There's no way I'm going to finish in 28 hours. I think I'll be able to keep up this week's average pace for 60 miles and then will slow down dramatically after that. We'll see!

  Next week I'm giving myself a break from long hilly runs. I'll do daily runs of not much more than an hour, yoga, some strength and conditioning. And I'll be working on my race day planning: gear, drop bags, fueling, etc.

• sur KAN T&IT Blog: XVII Jornadas IDERA: Nuestra Experiencia

  Publié: 25 August 2023, 7:56pm CEST

  Cada año, desde 2007, la Infraestructura de Datos Espaciales de la República Argentina (IDERA) extiende su invitación a los apasionados de la información geoespacial a unirse a las Jornadas IDERA. Este evento anual se ha convertido en una tradición, y en 2023, se llevó a cabo en la hermosa ciudad de Santa Rosa, provincia de La Pampa, Argentina. Es un hecho que IDERA se enorgullece de propiciar un espacio donde los expertos pueden compartir y celebrar los avances en el campo de la información geoespacial.

  El equipo de Kan participó de este evento, que tuvo como objetivo central impulsar la publicación de datos, productos y servicios geoespaciales de manera eficiente y oportuna, con la finalidad de respaldar la toma de decisiones basadas en evidencias. Las XVII Jornadas IDERA fueron el punto culminante de este esfuerzo, transformándose en el evento geoespacial del año en Argentina. Fue un momento invaluable para intercambiar ideas y debatir sobre los avances y desafíos relacionados con la publicación y utilización de información geoespacial abierta, interoperable y accesible para el desarrollo del país.

  Bajo el lema “La comunidad de IDERA hacia un marco integrado de información geoespacial”, las XVII Jornadas IDERA proporcionaron un espacio de reflexión sobre las propuestas globales emergentes destinadas a desarrollar, integrar y fortalecer la gestión de información geoespacial. Este enfoque permitirá mejorar las Infraestructuras de Datos Espaciales en los diferentes niveles jurisdiccionales de Argentina.

  

  La agenda de las XVII Jornadas IDERA estuvo repleta de eventos emocionantes y presentaciones interesantes. Los talleres y ponencias que realizamos desde Kan fueron los siguientes:

  Presentación institucional de KAN en el espacio de networking

  Taller “Potenciá el uso de tus datos geo con Geonode 4” 

  Presentación de casos de éxito en el grupo de provincias

  Taller “Recolección de datos en campo con Kobo” Ponencia “

  Desarrollo de un Sistema de Monitoreo y Manejo Integral de Humedales a partir de Información Satelital” 

  Además aprovechamos para compartir y asistir a otras charlas y muestras de nuestros colegas. Muchísimas gracias IDERA por esta oportunidad única para conectarnos con otros expertos, dejarnos aprender de sus experiencias y contribuir al avance de la comunidad de información geoespacial en Argentina. ¡Nos vemos el próximo año!

• sur Stefano Costa: Gli atti del workshop Archeofoss 2022 sono stati pubblicati

  Publié: 23 August 2023, 12:38pm CEST

  Gli atti del workshop Archeofoss 2022 sono stati pubblicati in open access su Archeologia e Calcolatori. Li trovate qui [www.archcalc.cnr.it] come numero 34.1 della rivista.

  Ho curato insieme a Julian Bogdani l’edizione di questo volume ed è quindi motivo di soddisfazione, anche per i tempi rapidi con cui siamo arrivati alla pubblicazione grazie al lavoro collettivo degli autori e autrici, di chi ha fatto il referaggio, della redazione e della casa editrice.

  Rimane una mancanza in questo volume rispetto alla ricchezza dei due giorni di incontro, delle sette sessioni tematiche, delle discussioni guidate da chi ha moderato le sessioni, ibride eppure vivacissime. La mancanza in parte è fisiologica ma in parte deriva da un certo numero di autrici e autori che non hanno presentato il proprio contributo per la pubblicazione. Ad esempio, nella sessione sui dati stratigrafici che ho moderato con Emanuel Demetrescu erano stati presentati 7 interventi ma solo 2 sono confluiti come paper nel volume.

  Nei prossimi anni dovremo fare di più per fare in modo che gli atti raccolgano ancora più fedelmente il convegno.

  Ci ritroveremo con la comunità Archeofoss a Torino nel mese di dicembre 2023.

• sur QGIS Blog: QGIS server 3.28 is officially OGC compliant

  Publié: 22 August 2023, 12:05pm CEST

  QGIS Server provides numerous services like WMS, WFS, WCS, WMTS and OGC API for Features. These last years, a lot of efforts were made to offer a robust implementation of the WMS 1.3.0 specification.

  We are pleased to announce that QGIS Server LTR 3.28 is now certified against WMS 1.3.0.

  

  This formal OGC certification process is performed once a year, specifically for the Long Term Release versions. But, as every change in QGIS source code is now tested against the formal OGC test suites (using OGC TeamEngine) to avoid any kind of regressions, you can always check any revision of the code against OGC failures in our Github continuous integration results.

  All this has been possible thanks to the QGIS’s sustaining members and contributors.

• sur Sean Gillies: Bear training week ~6 recap

  Publié: 20 August 2023, 8:14pm CEST

  For fun I'm using the bitwise complement operator ~ in the title of this post. Race week is week ~0. On Monday, it was 6 weeks to race week. I'm starting to feel fit, close to my 2020-2021 form.

  The numbers for the week:

  • 16 hours, 54 minutes

  • 71 miles

  • 12,165 feet D+

  I've run six days in a row and my shortest run was today's: an hour and 20 minutes. I went out for five hours in Rocky Mountain National Park on Wednesday, two hours in Lory State Park on Friday, and five and a half hours at Horsetooth Open Space on Saturday.

  

  Soaking hot and tired feet in the Big Thompson River below Fern Lake in RMNP.

  

  Below the Westridge Wall in Lory S.P.

  

  Alone on Arthur's Rock, looking NE across the reservoir and plains.

  

  Towers trail tailgating

  A bear was active around Towers Trail yesterday, but successfully avoided me. According to some bikers, it crossed the trail behind my back near the top during my first lap. If I'd turned when I heard them shouting, I might have seen it. I know there are bears up there, but have never seen one while I've been on the trail. It's a good time to be filling up on chokecherries, that's for sure.

  Next week I'm going to increase my training volume a little more. Instead of two 5.5 hour runs, I'll aim for 3 x 4 hours.

• sur Free and Open Source GIS Ramblings: I’ve archived my Tweets: Goodbye Twitter, Hello Mastodon

  Publié: 20 August 2023, 4:38pm CEST

  Today, Jeff Sikes @box464@firefish.social, alerted me to the fact that “Twitter has removed all media attachments from 2014 and prior” (source: [https:]] ). So far, it seems unclear whether this was intentional or a system failure (source: [https:]] ).

  Since I’ve been on Twitter since 2011, this means that some media files are now lost. While the loss of a few low-res images is probably not a major loss for humanity, I would prefer to have some control over when and how content I created vanishes. So, to avoid losing more content, I have followed Jeff’s recommendation to create a proper archival page:

  [https:]]

  It is based on an export I pulled in October 2022 when I started to use Mastodon as my primary social media account. Unfortunately, this export did not include media files.

  To follow me in the future, find me on:

  Btw, a recent study published on Nature News shows that Mastodon is the top-ranking Twitter replacement for scientists.

  To find other interesting people on Mastodon, there are many useful tools and lists, including, for example:

• sur Jackie Ng: Where's the new Maestro API nuget packages?

  Publié: 7 August 2023, 1:34am CEST

  There were a few things I left out of the previous announcement that I'll use this post to address.

  Firstly, the 6.0m12 release of MapGuide Maestro formally drops all Fusion editor support for integration with Google Maps tiles and services. We no longer support Google Maps integration in Fusion and the editor in previous releases gave the false impression that this is still possible. That is no longer the case with this release.

  Secondly, the more important thing (and the subject of this post) is that if you are using the Maestro API and consume this through nuget packages from nuget.org you may be wondering why there are no new versions?

  The answer to that one is simply: My nuget package publishing keys have expired and something in the nuget.org website or something with my nuget.org account is preventing me from regenerating these keys or to generate a fresh set. As a result, I currently cannot upload any new nuget packages to nuget.org

  But do not fret, because there is an alternative solution.

  As part of the MapGuide Maestro release on GitHub, the nuget .nupkg files are also included

  
  

  From here, you can set up a local directory-based nuget package source, drop the .nupkg files into it and the this version of the package is available to install in your Visual Studio solution.

  If/when I get a resolution on this publishing key matter, I will upload the .nupkg files for this release and make another announcement. Until then, this local package source is a suitable workaround.

• sur Narcélio de Sá: A Importância das Conferências do State of the Map para o OpenStreetMap

  Publié: 6 August 2023, 7:46pm CEST

  Se você teve a sorte de participar de uma conferência do State of the Map (SotM), já sabe que elas oferecem alguns dos melhores conhecimentos, habilidades e treinamentos em SIG (Sistemas de Informações Geográficas) e geoespaciais disponíveis. Isso é além de ser um evento de networking fantástico, com muito tempo social divertido e envolvente. Se você é novo na comunidade do OpenStreetMap e ainda não participou de um SotM, ou faz parte de uma empresa pensando em patrocinar um SotM, juntamente com o envio de uma equipe para participar, este post é para você.

  Image credit: Parker Michels-Boyce Photography. Please tag @OpenStreetMapUS in social media posts when using these photos. O que é um State of the Map – SotM?

  Os membros da comunidade do OpenStreetMap (OSM) organizam encontros anuais do State of the Map como uma forma de construir comunidade, compartilhar ferramentas e pesquisas, e estabelecer contatos entre si com o objetivo comum de melhorar o mapa. Esses encontros têm diversos tamanhos e são organizados local, regional e globalmente, mas o objetivo é sempre o mesmo: se reunir para discutir pesquisas sobre a criação de mapas, ferramentas, iniciativas e outros tópicos da comunidade. Os SotMs locais e regionais são organizados por comunidades locais, e o SotM global é organizado pela Fundação OSM.

  

  As conferências do Estado do Mapa estabelecem pontes entre os mapeadores do OSM e ativistas comunitários, desenvolvedores de código aberto, pesquisadores de universidades e instituições acadêmicas, designers, cartógrafos, bem como profissionais de tecnologia de empresas privadas e instituições públicas.

  Quais Tipos de Tópicos são Discutidos?

  A variedade de tópicos é tão diversa quanto a comunidade. As apresentações variam desde “palestras relâmpago” de 5 minutos até apresentações de 15-20 minutos e workshops de 75 minutos. Eles abordam temas como desenvolvimento de plataformas e ferramentas, análise de dados, mapeamento humanitário e muitos outros. Os apresentadores estão afiliados a comunidades locais, Youthmappers, HOTOSM, maplibre, FOSS4G, academia, outras organizações sem fins lucrativos e empresas pequenas e grandes.

  A conferência global SotM de 2022 em Firenze, Itália, fornece um bom exemplo da variedade de informações e habilidades representadas em um SotM. Aqui estão apenas alguns títulos de sessões: “OSM Carto as Vector tiles; Innovating on Derivative OpenStreetMap Datasets”, Mapping a Small Town”,  “maplibre-rs: Cross-platform Map Rendering using Rust”, “Ten Years iD Editor—The Road Ahead”, “Women Leadership in Mapping Riverside Communities in the Amazon Forest Using OSM.”

  Esses exemplos mal arranham a superfície. Aqui está o programa completo e as gravações das apresentações. Há também uma exposição de pôsteres – sim, até as paredes do SotM de 2022 eram educacionais! E há um resumo dos procedimentos acadêmicos.

  

  Portanto, como você pode ver, um SotM oferece inspiração e conhecimento para qualquer pessoa interessada no futuro da tecnologia geoespacial, OpenStreetMap e software e dados livres e de código aberto.

  Participe do State of the Map Curitiba 2023

• sur Sean Gillies: Never Summer training weekend recap

  Publié: 5 August 2023, 4:15am CEST

  Thursday, July 27, I drove west on CO-14 up the long Poudre River canyon and over Cameron Pass to Gould, the base for the Never Summer 60K and 100K races, for three days of camping and running in the mountains. Friday I would run the 60K race, Saturday I would go out for a few hours in the morning, and Sunday I would run a few more hours before driving home. Back-to-back-to-back easy long runs at high elevation to help me get in shape for the Bear 100 in September.

  I had completely fair weather for the drive and for setting up my tent. I tossed a drop bag with spare shoes and socks in the truck bound for the Bockman aid station, caught up with other runners who I haven't seen in a while, cooked some quinoa for dinner, and tucked myself in.

  

  Nokhu crags from Cameron Pass on CO-14

  Thunderstorms passed over Gould almost all night long. I slept fitfully, and struggled to get my act together before the 5:30 a.m. start. I tied my shoes in the last 30 seconds before race director Nick Clark let us go. Not being a morning person, getting to the start on time is always a challenge for me.

  After two miles of rolling along the margin of the valley floor, the course climbs steeply up Seven Utes Mountain. I stopped feeling groggy and started feeling the effort. I hiked the whole thing, comfortable at the back of the pack, and in a little over an hour, I was on top of the first alpine summit.

  

  Runners heading down from the summit of Seven Utes Mountain, mile 6

  My plan for the day was to go at an average pace of 20 minutes per mile. At the Bear 100, this would equate to a 33 hour finish, comfortably within the 36 hour cut off. I got to the Michigan Ditch aid station (11 miles) ahead of schedule and reached the Diamond Peak aid station (19 miles) 45 minutes ahead of schedule. The segment between them climbs 1000 feet, then becomes a highly runnable downhill. I ate solid food at the aid station, filled some pockets with cookies, and took 3 soft bottles of VFuel (race sponsor) solution to get me through the Diamond Peak climb and the ridge connection to Montgomery Pass.

  Sweltering conditions made the first part of the Diamond Peak climb tough. A steady breeze above treeline helped make the slow, steep slog up the ridge more comfortable. The last unforgettable mile of the climb has a vertical gain of 1370 feet.

  

  The ridge between North Diamond Peak and Montgomery Pass, mile 21

  I took it easy on top, taking lots of pictures with my phone, and texting them to my family. News from the course always makes my mom happy. I reached the Montgomery Pass aid station a little less than three hours after leaving the Diamond Peak aid station.

  I've been recovering from a back injury, perhaps from my crash at Kettle Moraine, and by the time I reached Montgomery Pass it had seized up. I wasn't able to do any consistent downhill running after this point. Still, seven hours of pain free running and hiking felt like major progress. I hope I'll be close to 100 percent by the Bear. I hiked down to Bockman aid station, did not change shoes and socks, grabbed more drinks and cookies, and hiked and jogged intermittently to the finish. I was just seven minutes over my goal.

  Fort Collins runners Clint Anders and Jenna Bensko won the men's and women's divisions. Full results are here on OpenSplitTime.

  Saturday morning I woke early to the sounds of the 100K race starting, dozed for another two hours, then drove 45 minutes to the Bockman aid station. It was dormant at 9. It is the 100K race's 50 mile mark and the first runner wouldn't be arriving before 2 p.m. From Bockman, I hiked the course in reverse to the Ruby Jewel aid station, then went forward on the course to the pass overlooking Kelly Lake, roughly mile 35. The lead runner and eventual winner, Zachary Russell, caught up to me just before the top. I stuck around to see the next ten runners come over, then headed back to Ruby Jewel. Saturday was warm, and the closer I got to Ruby Jewel, the more suffering I saw on faces. I heard later that 50 runners dropped out there at mile 31.

  

  Pass above Kelly Lake, mile 35

  I returned to Bockman, hung out there chatting with the aid station crew for a bit, then went for a swim in North Michigan Reservoir, a place where I've camped with my family, and which is full of water again after being drained for maintenance of the dam in 2021. After cooling and washing off, I returned to my camp at the race finish to change and get ready to work at the kitchen. From 6 p.m. until midnight I washed dishes and served food to runners. The kitchen group was a lot of fun and was lead by an actual chef who does the same duty at Hardrock 100 and a few other serious races. People are super grateful for a hot meal after a long day on the trail or at an aid station, and there isn't anywhere to eat in Gould. I would do this again.

  

  100K finish line

  I slept very little Saturday night. Runners trickled in until 6 a.m., and Brad Bishop (volunteer coordinator and finish line announcer among many roles) read every name and number over the PA system. On the bright side, I did hear names I knew, and was glad for them. My friend Ivan became the 100K race's first 70 year old finisher at 3:50 a.m.

  After breaking camp and packing my car, I said good-bye to people, and drove homewards, stopping at the American Lakes trailhead for one more trip to that beautiful alpine basin. This time I went all the way to Thunder Pass for the view into Rocky Mountain National Park.

  Over the weekend, I spent 20 hours on trails, covered 100 kilometers distance, and climbed over 4,000 meters. A successful mountain training camp, for sure. I got signs that my back is healing, did some volunteering, hung out with my favorite runners, and met some fun folks for the first time. I don't know if I'll run this next year, but I'll be back to be a part of it.

• sur Sean Gillies: Laid off

  Publié: 4 August 2023, 6:35pm CEST

  My position evaporated on Monday, one of many layoffs at my job. This is a first for me. If you've got advice, I'm all ears. If you're a former coworker and looking for help finding a new job, hit me up. I'm good at reviewing resumes and enjoy telling hiring managers good things about good people.

  I'm fortunate to be in a good position right now. My family is healthy, we are insured through Ruth's position at CSU, and have some savings. This is not the case for everyone who gets laid off, I know.

  Am I going to let this derail my attempt to finish a 100 miler in September? No way. Looking for work will take time, and I'm picking up more family duties, but it looks like I'll also have more free time to spend on the trail this summer.

• sur Jackie Ng: Announcing: MapGuide Maestro 6.0m12

  Publié: 1 August 2023, 10:41pm CEST

  Next stop on the tour: A new release of MapGuide Maestro

  This release includes the following notable changes.

  Improved MapGuide Open Source 4.0 authoring support

  This release improves the MapGuide Open Source 4.0 authoring experience with support for the new label justification setting for basic stylization labels.

  
  

  This setting is part of the new v4.0.0 Layer Definition XML schema, whose .xsd file is now also included with this release (so XML validation against this schema will work)

  Fusion editor enhancements for mapguide-react-layout features

  This release includes several enhancements to the Fusion Flexible Layout editor to support various features that can be taken advantage of when loaded into a mapguide-react-layout viewer. These new enhancements are accessible from the layout settings panel and require the latest release of mapguide-react-layout to leverage these new features.

  
  

  The Manage Custom Projections button opens up a new dialog that lets you manage and pre-register custom proj4 definitions for your application. By pre-registering these definitions in the Flexible Layout document itself, you can avoid needing to perform a epsg.io lookup for any projections found in the viewer init process that is not EPSG:4326 or EPSG:3857

  The Manage Settings button opens up a different dialog that lets you managed the app settings in the Flexible Layout document. These are arbitrary key/value pairs that your mapguide-react-layout viewer will be initialized with and your viewer code can read such settings at runtime to control and drive whatever custom functionality you may have.
  
  Other Changes

  • Improved layer editor UI responsiveness when layer points to a feature source with a really large schema
  • Increased schema walk/describe timeout to handle really large schemas
  • Fix: Connection error dialog buttons are no longer cut off
  • Fix: Transactional package drag-and-drop loading works again
  • Fix: Broken rest addin due to missing RestSharp dependency
  • Fix: Fill/line pattern dropdowns in layer editor are working again
  • Fix: MgTileSeeder will now accept bounding boxes outside the [-90, -180, 90, 180] lat/long domain by clamping any outside coordinates to be within this domain.

  Now onto the next stop: Finally giving mapguide-rest some long deserved attention!

• sur Stefano Costa: Sono vegetariano da due anni

  Publié: 27 July 2023, 9:07pm CEST

  In questi giorni di fine luglio, due anni fa, ho deciso di smettere di mangiare carne e pesce e animali. Per un po’ di tempo, mi sono detto, ci provo. E sono passati due anni. Perché?

  Non è stata una decisione improvvisa e penso che siano anni che mi porto dietro l’idea di non nutrirmi più di altri animali, ma l’ho sempre considerata molto difficile da attuare, molto faticosa da spiegare. E invece è stato piuttosto semplice.

  Sono arrivato a questa decisione da due strade, il rispetto per gli animali e la convinzione che non esista un futuro per l’umanità carnivora.

  Il rispetto per gli animali mi porta a rimanere inquieto sul consumo di prodotti di origine animale, in particolare latticini e uova, poiché la loro produzione su larga scala richiede necessariamente quegli allevamenti intensivi disumani da cui provengono gli animali destinati alla macellazione. Ho quindi grande rispetto per chi pratica una alimentazione vegana e non capisco perché la prima domanda che mi viene rivolta quando dico di essere vegetariano è se io non sia mica vegano, nemmeno fosse una malattia infettiva. Ho ridotto il consumo di latticini, soprattutto lo yogurt che ho sostituito con prodotti alternativi che sono in prevalenza a base di soia. La coltivazione di soia non distrugge le foreste amazzoniche, per inciso.

  Le considerazioni planetarie sono le stesse che vengono ripetute da anni nell’ambito del discorso sulla crisi climatica globale. L’allevamento consuma una quantità di suolo enormemente superiore alla superficie richiesta per coltivare le piante in grado di fornire lo stesso apporto nutritivo. L’allevamento produce gas serra. Non cedo ai finti fondamentalismi eco-fascisti e credo che le popolazioni che praticano allevamento tradizionale debbano poter continuare a praticarlo. La stessa cosa non può essere detta per l’allevamento industriale tipico dei paesi occidentali. Queste sono convinzioni personali, che vorrei trovassero sponda in ambito politico.

  Sono un archeologo, conosco abbastanza bene la storia della cultura materiale dell’umanità e credo che i cambiamenti culturali che continuamente avvengono siano ben più significativi di qualunque “tradizione” a cui si vuole rimanere aggrappati. La lista delle pratiche oggi ritenute incivili e inconcepibili che “abbiamo sempre fatto” è lunghissima, quindi non c’è nessun ostacolo concettuale ad aggiungerci anche il consumo di carne.

  Ora sono un po’ più tranquillo quando mi siedo a tavola.

  About QGIS contributor meetings

  QGIS Contributors Meetings are volunteer-driven events where contributors to the QGIS project from around the world get together in a common space – usually a university campus. During these events, contributors to the QGIS project take the opportunity to plan their work, hold face-to-face discussions and present new improvements to the QGIS project that they have been working on. Everybody attending the event donates their time to the project for the days of the event. As a project that is built primarily through online collaboration, these meetings provide a crucial ingredient to the future development of the QGIS project. The event is planned largely as an ‘unconference’ with minimal structured programme planning. We do this to allow attendees the freedom to meet dynamically with those they encounter at the event. Those sessions that are planned are advertised on the event web page, and we try to enable remote participation through video conferencing software. Although our hosts are not funded and donate the working space to us, we show our appreciation by making one of our software release’s splash screens in honour of that host, which is a great way to gain exposure of your institution and country to the hundreds of thousands of users that make use of QGIS.

  About OSGeo

  The Open Source Geospatial Foundation (OSGeo) has a long tradition of organizing code sprints for developers of Free and Open Source GIS software.

  Since 2009, the Open Source Geospatial Foundation (OSGeo) has been organizing a yearly Code Sprint of the “C Tribe” OSGeo projects, which has evolved into a full OSGeo Community Sprint and all “Tribes” are included/welcome. Leading developers of projects like GDAL, PostGIS,
  MapServer, GeoServer, GRASS, QGIS, PDAL, pygeoapi and many more get together to discuss new ideas, hack, decide, tackle large geospatial problems and have fun.

  The OSGeo Community Sprint is open to all who wish to participate in one or more projects. There is always plenty to do – it’s not all about programming. Translation, documentation, feedback, discussions, testing – all this is also important for projects so everyone is cordially invited to attend the code sprint!

• sur Volker Mische: FOSS4G 2023

  Publié: 22 July 2023, 9:50pm CEST

  Finally, after missing one virtual and one in person global FOSS4G I had again the chance to attend a global in-person FOSS4G conference. Thanks Protocol Labs for sending me. This year it was in Prizren, Kosovo. I’m a bit late with that post, but that’s due to doing some hiking in Albania right after the conference.

  The organization and venue

  Wow. It’s been my favourite venue of all FOSS4Gs I’ve been to so far. The exhibition hall was a great place to hang out, combined with the excellent idea of a 24h bar. I’m not sure if it was used at all times, but definitely for more than 20h a day. Outside, there was plenty of space and tables to hang out, and very close by another set of tables that formed the “work area”. Which was another great place to hang out, with enough power sockets and shade for the hot days.

  The main stage was an open air stage with enough seating for everyone. It was converted for the gala dinner to a stage with an excellent live band and the usual big round tables.

  For me, the best part was that even the accommodation was on-site. The barracks of the former military basis, which now serve as student dorms, were our home for a week. Pretty spartan, but at a conference I don’t really spend much time in my room, I mostly need just some place to sleep.

  Having everything, the talks, exhibition, social events and accommodations on-site makes it easy to maximize the time for socializing, which for me is the number one reason to attend a conference.

  Everything was well organized, and it was great to see so many volunteers around.

  The talks

  I haven’t really selected the talks I went to. I rather joined others where they were going, or listened to recommendations. Often, I just stayed in the rest of the slot to see what else is there. My favourite talks were:

  • Smart Maps for the UN and All - keeping web maps open: For me, it was the first time I saw someone speaking at a FOSS4G about using IPFS that wasn’t me. It’s great to see that it gains traction for the offline use case, where it just makes a lot of sense. UN Smart Maps is part of the UN OpenGIS initiative, it features a wide range of things, even an AI chatbot called TRIDENT that transforms the text into Overpass API calls. Try TRIDENT it out yourself, when you open the developer console, you can see the resulting Overpass API calls.
  • Offline web map server “UNVT Portable”: This talk got into more detail about using Raspberry Pis to have map data stored in IPFS for offline use. It’s very similar to what I envision, the only difference is that I’d also like to keep the storage in the browser. But I surely see a future, where those efforts are combined, to have a small easy server you can deploy, with in browser copies of subsets of the data to be able to work completely offline in the field. The original UNVT Portable repository doesn’t use IPFS, but Smart Maps Bazaar does, which seems to be its successor.
  • B6, Diagonal’s open source geospatial analysis engine: A presentation of the B6 tool for geospatial analysis for urban planning. It has a beautiful interface. I really like the idea of doing things directly on the map in a notebook-style way, where you perform certain steps after each other.
  • Elephant in the room: A talk about how many resources to computations take? Do we always need it? It’s very hard, often impossible, to find out how environmentally friendly some cloud services are. One of the conclusions was that cheaper providers likely use less power, hence are harming the environment less. I would like if there would be better ways (e.g. it misses things like economies of scale of large providers), but I agree that this might be the best metric we currently have. And I also hope there will be more economic pressure to save resources.
  • There was a closing keynote from Kyoung-Soo Eom, who was talking about his long journey in open source GIS, but also his history with Kosovo, where he was also on a mission in 1999. Quite inspiring.

  My talk

  My talk about Collaborative mapping without internet connectivity was about a browser based offline-first prototype that uses IPFS to enable replication to other peers. The project is called Colleemap and is dual-licensed under the MIT and Apache 2.0 license. Although I tried the demo bazillion times before my talk, it sadly didn’t work during my talk. Though, trying it later with various people, I was able to get 4 peers connected once. I even saw it working on a Windows machine. So it really works cross-platform.

  For the future I hope to work closer with the people from the UN OpenGIS initiative, it would be great to combine it with their Raspberry Pi based prototype.

  Things I’ve learnt

  The Sentinel-2 satellite imagery is available from multiple sources, directly from Copernicus Open Access Hub or through cloud providers like AWS, Azure of Google Cloud. From the cloud providers you only get the level-2 data. They might use the original level-2 data or do their own atmospheric correction based on the level-1 data. Or even re-encode the data. So it’s hard to tell which kind of data you actually get.

  As far as I know (please let me know if I’m wrong), there isn’t any mirror of the full level-1c data. You can only get it through the Copernicus Open Access Hub and there the older images are stored in the long term archive on tape, where it can take up to 24h for the data to be available for download (if it works).

  Ideally, there would be a mirror of the full level-1c data (where the ESA would provide checksums of their files) and a level-2 version, where the exact process is openly published, so that you can verify how it was created. The problem is the storage cost. The current level-2 data is about 25 PiB, which leads to storage costs of over $500k USD a month if you would store it on AWS S3 Standard at the current pricing (I used the $0.021 per GB).

  Final thoughts

  It was great to meet Gresa and Valmir from the local organizing committee before the FOSS4G in March at the OSGeo German language chapter conference FOSSGIS in Berlin. That made it easy for me to connect to the event right from the start. If there’s one thing future FOSS4Gs should adapt, it’s the cheap on-site (or close by) accommodation. I think that shared bathrooms is also much smoother to have, if you know that everyone in the accommodation is from the conference. We had something similar with the BaseCamp in Bonn during the FOSS4G 2016 and the international code spring in 2018 during the FOSSGIS conference, where the whole place was rented for the time of the events.

  Though, of course, I also missed some of my longtime FOSS4G friends I hadn’t seen in a long time. I hope you’re all doing well and will meet again soon.
