  GeoServer Team: GeoServer 2.24.0 Release

  sur Planet OSGeo

  GeoServer 2.24.0 release is now available with downloads (bin, war, windows), along with docs and extensions.

  This is a stable release of GeoServer recommended for production use. GeoServer 2.24.0 is made in conjunction with GeoTools 30.0, mapfish-print-v2 2.3.0 and GeoWebCache 1.24.0.

  Thanks to Peter Smythe (AfriGIS) and Jody Garnett (GeoCat) for making this release.

  Thanks to everyone who helped test the release candidate: JP Motaung & Nicolas Kemp, Georg Weickelt, Peter Smythe, Tobia Di Pisa, and Giovanni Allegri.

  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.

  

  

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

  • GEOS-10972 Resource page CRS editors would not work with authorities other than EPSG

  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.

  • GSIP 218 - Control remote HTTP requests sent by GeoTools \ GeoServer
  • GEOS-10949 Control remote resources accessed by GeoServer
  • GEOS-11048 Improve URL checking

  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.

  • 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 “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.

  A recap of the 127th OGC Member Meeting, Singapore

  sur Open Geospatial Consortium (OGC)

  From September 25-29, 2023, more than 100 geospatial experts from around the world converged in Singapore to attend OGC’s 127th Member Meeting, with another 100+ attending online. As always, big thanks go out to our dedicated members that either attended in-person, or juggled lives across multiple timezones to attend virtually.

  Sponsored by OGC Principal Member, the Singapore Land Authority (SLA), the meeting was themed “Building future standards for the next generation of geospatial experts.” Once again, the Member Meeting was held in conjunction with the Singapore Geospatial Festival 2023 operated by SLA’s GeoWorks.

  Alongside the usual assortment of Standards Working Group (SWG) and Domain Working Group (DWG) meetings, the Member Meeting also saw several special sessions, including: a two-part Data Quality Workshop; a session on Modeling of Humanities’ Spatio-Temporal Data; a Digital Twins special session; a session on the OGC Academy; a Connecting Land and Sea special session; an Intelligent Transportation Systems (ITS) ad hoc; and a meeting of the OGC Asia Forum.

  Monday evening’s welcome reception celebrated Simple Features’ 25th birthday with a suitably delicious cake and an enthusiastic rendition of “Happy Birthday.” Simple Features, which is jointly published with ISO, is OGC’s earliest standard and describes how to model the location of “features” (a geometric representation of anything of interest) on a 2-dimensional space representing the surface of a planet. And of course there was the usual Wednesday night “VIP Dinner” (held at the delicious Red House Seafood), where Wuhan University received an OGC Community Impact Award, and a Diversity Luncheon held on Thursday.

  OGC Chief Standards Officer, Scott Simmons, leads the celebrations for Simple Features’ 25th birthday. Themes from the week

  As is befitting of the location in Singapore, with its advanced modeling of the whole nation, across the entirety of the Member Meeting were presentations related to Digital Twins – twins not only of the built environment, but for vegetation, the ocean, and the subsurface. Several Working Groups regularly include discussion on Digital Twins related to their scope, especially the Urban Digital Twins DWG. Related topics regarding the Metaverse and Interoperable Simulation and Gaming also continue regular appearances at OGC meetings.

  Marine and coastlines play an important role in economies and climate resilience strategies alike. OGC has a long-running pilot project on marine geospatial infrastructure, and we continue to refine models for describing and managing the coastal land-sea interface. We expect this work to be extended to the topics of ITS and logistics in the coming years, too.

  A Kick-off and a Joint Opening

  The OGC Member Meeting started on Monday, but as it was held jointly with the Singapore Geospatial Festival, the joint opening wasn’t until Tuesday. Monday, then, kicked off with a brief welcome session before the ever-popular Today’s Innovations, Tomorrow’s Technologies and Future Directions session.

  The topic of this meeting’s Future Directions session was Geospatial Artificial Intelligence. Dr. Gobe Hobona, OGC’s Director of Product Management, opened with an overview of where this topic fits in the context of previous sessions. He was then followed by three presentations:

  • Kyoung-Sook Kim from the National Institute of Advanced Industrial Science & Technology (AIST) presented a Design Standardization Roadmap for GeoAI.
  • Peter Baumann, Dimitar Misev, and Otoniel Campos  of Constructor University (formerly Jacobs University) presented on Scalable Datacube-Enabled AI Infrastructure Based on Open Standards.
  • Amey Godse and Sunil Shah of Duality Robotics presented on Building Digital Site Twins Using Geospatial Data and Artificial Intelligence.

  The speakers then participated in a panel fielding audience questions, including their views on the fundamental scope of the AI domain in a geospatial context, and what types of machine learning need OGC’s attention and which may be less relevant. OGC Members can access the presentations and a recording on this page in the OGC Portal.

  The joint Opening session on Tuesday featured keynote remarks from Colin Low, Chief Executive, SLA, and myself. The Guest of Honor was Dr. Mohamad Maliki Bin Osman, Minister in the Prime Minister’s Office, Second Minister for Education & Foreign Affairs. The session also featured presentations from local students who had performed impressive geospatial projects in their primary schools. It finished with a panel on “Geospatial: Enriching Minds, Empowering Lives,” which was also the key theme for the Singapore Geospatial Festival.

  The theme of the Member Meeting was “Building future standards for the next generation of geospatial experts.” Meeting Special Sessions

  The week continued with its usual array of SWG and DWG meetings, interspersed with several special sessions, outlined below. 

  The OGC Data Quality DWG held two sessions to comprise a workshop covering a breadth of data quality topics. The first session focused on the work of ISO/TC 211 on data quality measures and a registry to be hosted by OGC. The second session included presentations on the data quality requirements and considerations for a variety of types of geospatial data, including 3D and imagery. OGC Members can access the presentations and a recording on this page in the OGC Portal. 

  The session on Modeling of Humanities’ Spatio-Temporal Data was organized by participants in the HumSpatial Consortium, in which OGC participates, to address the complexities of representing “named places” in geospatial technologies. Presentations were given by scholars and practitioners from the humanities research and government sectors heavily involved with place-names and other types of geospatial data. OGC Members can access the presentations and a recording on this page in the OGC Portal. 

  Several sessions over the course of the week included presentations related to Digital Twins, often in the context of other domains, such as Artificial Intelligence or Data Quality. A dedicated special session for Digital Twins was organized to demonstrate different information types and practices and facilitate discussion on the relative meaning/relationship between digital twins, the metaverse, and the industrial metaverse. OGC Members can access the presentations and a recording on this page in the OGC Portal.  

  The OGC Academy is an information portal for distributing OGC knowledge related to the work of the Consortium and general geospatial interoperability. The web-based resources are under development with an estimated completion in 2026. Content is continuously refreshed. This session discussed capacity building and the academy more broadly. OGC Members can access the presentations and a recording on this page in the OGC Portal.

  The OGC Marine DWG organized a follow-up session to the one hosted last year in Singapore on “Connecting Land and Sea” to highlight activities in the OGC Federated Marine Spatial Data Infrastructure Pilot as well as work from OGC members around the world. OGC Members can access the presentations and a recording on this page in the OGC Portal. 

  The Intelligent Transportation Systems (ITS) ad hoc session highlighted work in ISO/TC 204, with whom OGC maintains a liaison, and explored the next steps for related work in OGC. Attendees generally accepted that ITS work intersected several OGC Working Groups and that a new effort to refine the road network model developed in TC 204 would be suitable for OGC activities. OGC Members can access the presentations and a recording on this page in the OGC Portal.

  At each OGC Member Meeting, one or more local forums meet to present and discuss topics of regional interest. On Friday of the Member Meeting, the OGC Asia forum offered a short history on the forum and five presentations from across the region. OGC Members can access the presentations and a recording on this page in the OGC Portal. 

  Winston Yap from the National University of Singapore’s Urban Analytics Lab presents during the Digital Twins Special Session. Closing and Important Things

  The Member Meeting’s Closing session began with the Important Things session and my rapid, 15-minute summary of the entire meeting week that included slides and content from a large number of Working Group sessions. OGC Members can access the presentation and a recording on this page in the OGC Portal.

  The Important Things session then proceeded with two discussion topics:

  • “Is the ‘fundamental model’ of geospatial 2D, 3D, 4D, or more D?” with consideration to whether the minimum number of dimensions is necessary, or whether all dimensions should just be assumed.
  • “The need to establish a policy for the governance of building blocks” where the TC concluded that more discrete definitions are needed for “building blocks” and other registered items that act as useful components in geospatial architecture.

  Notes from the session were recorded in the Etherpad “Important-Things-2023-09”, which is available to OGC Members via the Portal.

  The formal Closing Plenary then followed, which focuses on Working Group presentations and voting. The session advanced a number of Standards, SWGs, and documents toward vote or publication, so keep your eye on our news page, or subscribe to the “Standards updates” topic on the OGC Mailing List to get notifications sent straight to your inbox.

  Sean Gillies: Bear 100 recap

  sur Planet OSGeo

  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.

  OGC and the International Data Spaces Association sign Memorandum of Understanding

  sur Open Geospatial Consortium (OGC)

  The Open Geospatial Consortium (OGC) and the International Data Spaces Association (IDSA) have signed a Memorandum of Understanding (MoU) that outlines how they will together contribute to a flourishing data economy through the creation and development of standards for data spaces that ensure sovereign, interoperable, and trusted data sharing.

  “As the number of available data sources continues to grow, the challenge of integrating them into high-value products becomes ever greater,” commented OGC Chief Technology Innovation Officer, Ingo Simonis, Ph.D. “In order to develop effective solutions for cross-border data integration, international collaboration is critical. As such, OGC is eager to work with IDSA to tackle this task together.”

  “Committed to driving digital transformation, IDSA champions economic growth, innovation, and a cohesive data-sharing approach,” said Silvia Castellvi, Director of Research & Standardization at IDSA. “Partnering with OGC ensures our standards align and resonate. Enhancing features, like the geolocation of IDS Connectors, not only advances our standard but boosts its appeal for future developers and users.”

  OGC is an international non-profit consortium aiming to make geospatial (location) information and data services FAIR – Findable, Accessible, Interoperable, and Reusable. IDSA is an international non-profit association that follows a user-driven approach to create a global standard for international data spaces and interfaces based on sovereign data sharing. 

  The MoU seeks to align activities between the two organizations so that OGC and IDSA Standards can work in tandem. This will be achieved in part through joint participation in potential future projects and initiatives, particularly in the areas of global supply chains, intelligent transport, and smart city data spaces.

  Projects in global supply chains and intelligent transport may include developing solutions that support the monitoring of shipping routes, tracking freight, sharing ocean currents and weather data, and more. Projects in smart city data spaces could focus on improving data sharing from business and technical perspectives, and could include data ranging from traffic to population migration.

  The two organizations have already identified several ongoing or completed projects relevant to their work together, including: Divine, Flexigrobots, DEMETER, ATLAS & AgriDataValue, Iliad, AD4GD, OGC Rainbow, and others.

  About IDSA
  The International Data Spaces Association (IDSA) is on a mission to create the future of the global, digital economy. Its 140+ member companies and institutions have created the International Data Spaces (IDS) standard: a secure system of sovereign and trusted data sharing in which all participants can realize the full value of their data. IDS enables new smart services and innovative business processes to work across companies and industries, while ensuring that the control of data remains in the hands of data providers. We call this data sovereignty.

  CoverageJSON v1.0 Adopted as OGC Community Standard

  sur Open Geospatial Consortium (OGC)

  The Open Geospatial Consortium (OGC) is excited to announce that version 1.0 of CoverageJSON has been approved by the OGC Membership for adoption as an official OGC Community Standard. CoverageJSON enables the development of interactive visualizations that display and manipulate spatio-temporal data within a web browser.

  The key design goals for CoverageJSON are simplicity, machine and human readability, and efficiency in the storage and use of complex data. 

  Coverages and collections of coverages can be encoded using CoverageJSON. Coverage data may be gridded or non-gridded, and data values may represent continuous values (such as temperature) or discrete categories (such as classes of land cover). 

  This OGC Community Standard was an outcome of the European Union project “Maximizing the Exploitation of Linked Open Data in Enterprise and Science” (MELODIES), which ran from 2013 to 2016, and was released under a Creative Commons 4.0 License by the University of Reading. There are several widely-used open source implementations and libraries available. Furthermore, CoverageJSON is one of the encodings supported by the OGC API – Environmental Data Retrieval Standard.

  CoverageJSON is based on the popular JavaScript Object Notation (JSON), and provides an effective, efficient format that’s friendly to web and application developers and consistent with the OGC API family of Standards. 

  CoverageJSON supports the efficient transfer of usable quantities of data from big data stores to lightweight clients, such as browsers and mobile applications. This enables straightforward local manipulation of the data by scientists and other users.

  The simplest and most common use-case is to embed all the data values of all variables in a Coverage object within the CoverageJSON document to create a self-contained, standalone, document that supports the use of very simple clients.

  Another simple use case is to put data values for each variable (parameter) in separate array objects in separate CoverageJSON documents that are linked from a parent CoverageJSON object. This is useful for a multi-variable dataset, such as one with temperature, humidity, wind speed, etc., to be recorded in separate files. This allows the client to load only the variables of interest.

  A sophisticated use case is to use tiling objects, where the data values are partitioned spatially and temporally, so that a single variable’s data values would be split among several documents. A simple example of this use case is encoding each time step of a dataset into a separate file, but the tiles could also be divided spatially, like a tiled map server implementation.

  As with any OGC Standard, the OGC CoverageJSON Community Standard is free to download and implement. Interested parties can learn more about, view, and download the Standard from OGC’s CoverageJSON Community Standard Page.

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

  sur Planet OSGeo
  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.

  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.

  OGC Adopts Training Data Markup Language for Artificial Intelligence Conceptual Model as Official Standard

  sur Open Geospatial Consortium (OGC)

  The Open Geospatial Consortium (OGC) is excited to announce that the OGC Membership has approved the OGC Training Data Markup Language for Artificial Intelligence (TrainingDML-AI) Part 1: Conceptual Model for adoption as an official OGC Standard. The Standard defines the conceptual model for standardized geospatial training data for Machine Learning.

  Training data plays a fundamental role in Earth Observation (EO) Artificial Intelligence Machine Learning (AI/ML) applications, especially Deep Learning (DL). It is used to train, validate, and test AI/ML models. Understanding the source and applicability of training data allows for better understanding of the results of AI/ML operations.

  To maximize the interoperability and re-usability of geospatial training data, the TrainingDML-AI Standard defines a model and encodings consistent with the OGC Standards baseline to exchange and retrieve the training data via the Web. Part 1 of the Standard contains the Conceptual Model, as well as example JSON encodings. Future Parts of the Standard will cover other encodings.

  Additionally, the Standard provides detailed metadata for formalizing the information model of training data. This includes but is not limited to the following aspects: 

  • How the training data is prepared, such as provenance and quality;
  • How to specify different metadata used for different ML tasks;
  • How to differentiate the high-level training data information model and extended information models specific to various ML applications;
  • How to describe the version, license, and training data size;
  • How to introduce external classification schemes and flexible means for representing ground-truth labeling.

  OGC Members interested in staying up to date on future progress of this standard, or contributing to its development, are encouraged to join the Training Data Markup Language for AI Standards Working Group via the OGC Portal. Non-OGC members who would like to know more about participating in this SWG are encouraged to contact the OGC Standards Program.

  As with any OGC standard, the open OGC Training Data Markup Language for Artificial Intelligence (TrainingDML-AI) Part 1: Conceptual Model Standard is free to download and implement.

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

  sur Planet OSGeo

  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.

  GeoServer Team: GeoServer 2.24-RC Release

  sur Planet OSGeo

  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.

  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.

  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-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.

  Gabriel Roldan is the contact point for anyone interested in this work.

  • GSIP 217 - GeoServer ACL project

  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.

  Sean Gillies: Bear 100 race week

  sur Planet OSGeo

  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.

  Making The Data Count, Not Just Counting The Data

  sur Open Geospatial Consortium (OGC)

  After three years of collaborative development, the release of the first iteration of the IGIF-(M)SDI Maturity Roadmap is a milestone moment in exploiting geospatial data for the inclusive socio-economic development of nations. This Maturity Roadmap – involving the UK Hydrographic Office (UKHO) as lead sponsor, as well as the Open Geospatial Consortium (OGC), the World Bank Group, and the US National Oceanic and Atmospheric Administration (NOAA) – complements existing resources by providing a quantitative toolkit for nations, ministries, departments, agencies, regions, municipalities, and even individual cities or ports, to benchmark their geospatial development against the United Nations’ Integrated Geospatial Information Framework (IGIF) principles. This independent initiative aligns with, and supports, the mission, vision, and goals of the UN-GGIM initiative (Global Geospatial Information Management), who developed the IGIF core principles for all geospatial data considerations.

  (Marine) Spatial Data Infrastructure

  IGIF provides a vision for developing and strengthening geospatial information management, to assist countries in bridging the geospatial digital divide, secure socio-economic prosperity, and leave no community behind. Marine Spatial Data Infrastructure ((M)SDI) is the International Hydrographic Organization (IHO)’s concept for a future ecosystem of marine data services that can enable the IGIF vision to become a reality. Empowered by OGC standards, the interoperable (M)SDI data services can “make it real through technology.” Bringing these elements together in a straightforward and accessible document, the intent of the Maturity Roadmap is to provide a quantitative “quick start” or “stepping stone” for nations beginning an IGIF-aligned (M)SDI implementation.

  With its terrestrial heritage, the World Bank SDI Diagnostic Toolkit is augmented with IHO and OGC contributions to maximise its benefits to the marine community, while remaining aligned with the IGIF principles and, therefore, the UN Sustainable Development Goals (SDGs). As a guiding simplification, the involvement of the World Bank is crucial in providing answers for questions around financing (including business cases), alongside the ‘why’ (UN), ‘what’ (IHO), and ‘how’ (OGC). This aspect of measuring socio-economic return is commonly a key hurdle that prevents real-world progress beyond concepts and ideas. The modular IHO and OGC additions ensure interoperability with the World Bank IGIF methodology, which can lead to the financing of approved (M)SDI development projects. Even as an independent tool, undertaking an (M)SDI assessment provides a clear reference point aligned with international best practice. Without such a starting point, progress towards any (M)SDI end-state will be difficult to govern and manage.

  Fully interoperable across all geospatial domains

  As part of the OGC’s Federated Marine SDI (FMSDI) initiative, the Maturity Roadmap seeks to promote the inclusive development of an IGIF-Aligned (M)SDI as the marine and maritime community’s contribution to an all-domain National Spatial Data Infrastructure (NSDI) across air, land, sea, space, and cyberspace. Although initially adapted for marine considerations, the Maturity Roadmap is fully interoperable across all geospatial domains and scalable from the national level to regions, municipalities, cities, ports, and government departments or agencies.

  

  Within the Maturity Roadmap, the concept of an IGIF-(M)SDI Balanced Pathway of Development seeks to promote inclusive geospatial development via two key messages: ‘driving technology, not being driven by technology’ and ‘making the data count, not just counting the data.’ 

  These twin ideas promote the effective governance of technology & standards to meet sovereign national requirements, however expansive or constrained, over the acquisition and possession of the latest technological solutions independent of cost-benefit considerations. OGC contributes to this by providing best practice around the implementation of standards, alongside an active cross-sector global forum to share applied knowledge, cooperate on emerging technologies, and collaborate on standards development. The engagement of the OGC membership at all levels of socio-economic development is vital for realising the cost benefits stemming from the common implementation of technologies across different countries, regions, sectors, and communities, regardless of economic spend.

  The benefits of benchmarking IGIF-MSDI maturity

  When objectively and independently applied, the benchmarking provided by the IGIF-(M)SDI Maturity Roadmap offers a useful planning and comparison baseline for countries undertaking a public geospatial development programme. The example here is a radar chart output across nine assessment categories corresponding to the IGIF Nine Pathways, for an initial baseline – and a subsequent baseline two years later. The underlying data is from real-world assessments taken under World Bank and partner oversight, which was openly published by the Agency for Land Relations and Cadastre of the Republic of Moldova. Such benchmarking exercises can be executed across different scales (from whole nations to cities or ports) and across different domains (from space to cyberspace), sometimes yielding deep insights into potential opportunities around discovered disparities.

  

  Also included with the Maturity Roadmap is a practically orientated appendix that covers best practice for multi-agency governance, where, during a national geospatial development programme, multiple agencies or departments may have to work closely to operationally deliver joint geospatial outcomes. This may be useful in situations where long-standing traditions and conventions could have created a culture that is not conducive to the tight-knit cooperation needed to develop complex IGIF-(M)SDI solutions. Such solutions require the pooling of expertise, resources, and capabilities that one or even two agencies can not provide alone.

  Positive approach to improve ineffective practices is essential to joint IGIF-(M)SDI success

  One crucial characteristic for joint IGIF-(M)SDI success is a healthy scepticism and a drive to improve ineffective practices, especially when they have become entrenched as tradition, convention, or “how things have always been done.” I like to counter such perceptions, particularly amongst those that genuinely want to evolve, with the view that “if you always do what you’ve always done, you’ll always get what you’ve always gotten.” Long-term existing practices may have been fine because they met some requirement in a particular environment and once satisfied a need effectively. However, maintaining those same practices now, when society’s expectations and technology have moved forward, can lead to stagnation.

  Departments and agencies should foster a keen interest in human behaviour around the use (and misuse) of data or information. Traditional or conventional “hard governance” centres around the assumption that people only make the wrong decisions because they have the wrong information or not enough of it. This traditional view of data governance then coalesces into hard compliance measures and management surveillance, which includes formal audits, regular in-depth reporting, restrictive checklists, and a focus on top-down, non-negotiable command & control. This approach was suited to traditional mass manufacturing of standardised products, but is insufficient by itself for modern data services that are digital-first by design and characterised by near real-time changes.

  Soft governance works with the grain of human behaviour to achieve better results by enablement and empowerment, rather than by command and control alone. Principles take precedent over prescription, thus allowing an organisation to leverage the deep insights and frontline experiences of their entire workforce. Shortcut thinking, lack of active engagement and wrong assumptions are some of the key targets for a soft governance approach, which still requires the ultimate backstop of hard governance – but meaningfully targeted and monitored using a risk-based approach. Combining the two approaches can yield outsized and transformative results, which is essential for joint IGIF-(M)SDI success that leaves no community behind.

  The IGIF-(M)SDI Maturity Roadmap and related resources are available for free on OGC’s IGIF-(M)SDI Maturity Roadmap webpage. 

  To best inform future revisions, iterations, and the optimization of the Roadmap, feedback and applied experiences from the geospatial community are sought via OGC Member Meetings, Forums, or directly.

  The IGIF-(M)SDI Maturity Roadmap is an independent initiative not endorsed by or officially connected to, but in alignment and support of, the mission, vision, and goals of the United Nations Initiative on Global Geospatial Information Management (UN-GGIM).

  

  Dr. Gerald J Wong is the Data Governance Lead at the United Kingdom Hydrographic Office (UKHO), which is a world-leading centre for hydrography and an executive agency of the Ministry of Defence (MoD). Dr Wong is the Lead Author of the IGIF-(M)SDI Maturity Roadmap, being a specialist in synergising traditional rules-based hard governance with modern and empowering soft governance, which works with the grain of human behaviour to achieve better outcomes.

  As an OGC Strategic Member and a sponsor of OGC’s FMSDI initiative, the United Kingdom Hydrographic Office (UKHO) is the UK’s agency for providing hydrographic and marine geospatial data to mariners and maritime organisations across the world. The UKHO is responsible for operational support to the Royal Navy and other defence customers. Supplying defence and the commercial shipping industry, the organisation helps ensure Safety of Life at Sea (SOLAS), protect the marine environment, and support the efficiency of global trade.

  Together with other national hydrographic offices and the International Hydrographic Organization (IHO), the UKHO works to develop and raise global standards of hydrography, cartography, and navigation. The UKHO also produces a commercial portfolio of ADMIRALTY Maritime Data Solutions, providing SOLAS-compliant charts, publications, and digital services for ships trading internationally.

  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!

  Registrations Open for OGC’s October 2023 Open Standards Code Sprint

  sur Open Geospatial Consortium (OGC)

  The Open Geospatial Consortium (OGC) invites software developers to the October 2023 Open Standards Code Sprint. The hybrid event will be held on Oct. 30 to Nov. 1, with the face-to-face element held at the Geovation Hub in London. A pre-event webinar will be held on October 12th. Participation is free and open to the public. Registration is available on the OGC Open Standards Code Sprint website. Travel support funding is available.

  The Code Sprint is sponsored at the Gold Level by OGC Strategic Member Ordnance Survey (OS), and at the Silver Level by OGC Member the European Union Satellite Centre (SatCen). Additional support comes from OGC Strategic Member the US National Geospatial Intelligence Agency (NGA) and OGC Principal Member the UK Defence Science and Technology Laboratory (Dstl). Additional sponsorship opportunities remain available for organizations to support the geospatial development community while promoting their products or services. Visit the Event Sponsorship page for more information.

  The code sprint will be a collaborative and inclusive event to support the development of Open Standards and supporting applications. All OGC Standards are in scope for this code sprint. 

  OGC code sprints experiment with emerging ideas in the context of geospatial standards, help improve interoperability of existing standards by experimenting with new extensions or profiles, and are used for building proofs-of-concept to support standards development activities and enhancement of software products. 

  Non-coding activities such as testing, working on documentation, or reporting issues are also welcome during the code sprint. The Code Sprint also provides the opportunity, via its mentor stream, to onboard developers new to OGC Standards.

  A one-hour pre-event webinar will take place on October 12 at 14:00 BST (UTC+1). The webinar will outline the scope of work for the code sprint and provide other useful information for participants. Any participants interested in Imagery formats will be invited to stay on after the webinar for a technical overview of the formats in focus for the code sprint. As with the virtual portion of the sprint, the pre-event webinar will take place on OGC’s Discord server.

  The Code Sprint will prototype and advance implementations of multiple approved and candidate OGC Standards, for example:

  • OGC API Standards including SensorThings
  • GeoPose
  • OGC CDB
  • JSON-FG
  • OGC Styles & Symbology
  • OGC MUDDI

  …and more.

  In the context of OGC Standards, the Code Sprint will also experiment with the ability to access or provide imagery conforming to NGA’s emerging GEOINT Imagery Media for ISR (GIMI) Profile through implementations of OGC API Standards. The GIMI Profile is based on the ISO/IEC 23008-12 High Efficiently Image File Format (HEIF) and the ISO/IEC 14496-12 ISO Base Media File Format (ISOBMFF) standards. This part of the Code Sprint will also prototype creation of GIMI files from still imagery encoded in JPEG 2000 (with GMLJP2), and motion imagery encoded in H.264 and H.265 formats.

  Some Travel Support Funding is available for selected participants. Anyone interested in receiving travel support funding should indicate their interest on the registration form. Requests for funding will need to be received before October 2. They will be notified within 2 weeks of their application whether their application for travel support is approved or not.

  The code sprint begins at 09:00 UTC on October 30 with an onboarding session, and ends at 17:00 UTC on November 1. To learn more about future and previous OGC code sprints, visit the OGC Developer Events Wiki or join OGC’s Discord server.

  In 2014 around 3,438,482 Americans lived within 1 mile of a mass shooting event. That number is very high - especially when compared to most other countries around the world. However because of America's complete failure to control gun ownership that figure has now grown to a frightening 41,930,273. This means that in 2023 over 12% of Americans live within one mile of a mass shooting.

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

  sur Planet OSGeo

  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.

  Sean Gillies: Bear training week ~5 recap

  sur Planet OSGeo

  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.

  OGC forms new GeoParquet Standards Working Group

  sur Open Geospatial Consortium (OGC)

  The Open Geospatial Consortium (OGC) is excited to announce the formation of the OGC GeoParquet Standards Working Group (SWG). The new SWG will work to advance the GeoParquet encoding format for adoption as an OGC Encoding Standard for cloud-native vector data. 

  GeoParquet adds geospatial types to Apache Parquet, described by Apache as “an open source, column-oriented data file format designed for efficient data storage and retrieval. It provides efficient data compression and encoding schemes with enhanced performance to handle complex data in bulk.” For an introduction to the GeoParquet format, see this blog post.

  GeoParquet started over 3 years ago as a community effort by different Open Source Projects and organizations that have committed to its implementation and support. 

  OGC is advancing a number of Standards to enable cloud-native geospatial ecosystems. GeoParquet fits in the group of data encoding Standards that are highly performant for large, cloud-based data stores, such as Cloud Optimized GeoTIFF for tiled rasters and Zarr for datacubes. GeoParquet will, in time, enable vector datasets to be as readily accessible from the cloud as the other formats already well-used in the community.

  The GeoParquet SWG will take the initial efforts incubated in OGC’s GeoParquet GitHub repository as a draft specification from which a candidate Standard will be developed. As with many other recent OGC Standards, the repository will remain open to contributions from outside OGC and documentation will evolve in concert with prototype implementations.

  GeoParquet will be another encoding of the OGC Simple Features Standard, and as such will handle all Simple Feature geometries. While other OGC Standards also encode Simple Features, GeoParquet is intended to be optimized for native use in cloud environments. It is expected that GeoParquet will be tested as an encoding to be accessed by the OGC API family of Standards. The new SWG expects to have a candidate Standard ready for review and approval within one year.

  The OGC GeoParquet Standards Working Group Charter is publicly available via the OGC Portal.

  OGC Members can join the GeoParquet Standards Working Group via the OGC Portal. Non-OGC members are welcomed to contribute via OGC’s GeoParquet GitHub repository or by joining the OGC GeoParquet SWG Mailing List. Non-OGC members who would like to know more about full participation in the SWG are encouraged to contact the OGC Standards Program.

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

  sur Planet OSGeo

  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.
