Marco Bernasocchi: Analyzing and visualizing large-scale fire events using QGIS processing with ST-DBSCAN
sur Planet OSGeoA 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 dataNASA’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 analysisThe 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 mapOnce 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 histogramThrough 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.

From GIS to Remote Sensing: Road to the Semi-Automatic Classification Plugin v.8: Landsat and Sentinel-2 images download and preprocessing, classification
sur Planet OSGeoThis is the second post describing the main new features of the new version 8 (codename "Infinity") of the Semi-Automatic Classification Plugin (SCP) for QGIS, which will be released in October 2023.The new version is based on Remotior Sensus, a new Python processing framework.
The tool "Download products" has been updated to download Landsat and Sentinel-2 images from different services. In particular, through the service NASA Earthdata (registration required at [https:]] ) it will be possible to download the Harmonized Landsat and Sentinel-2 which are surface reflectance data product (generated with Landsat 8, Landsat 9, and Sentinel-2 data) with observations every two to three days at 30m spatial resolution (for more information read here). This is therefore a great source for frequent and homogeneous monitoring.Moreover, Copernicus Sentinel-2 images will be searched through the Copernicus Data Space Ecosystem API, while the images are downloaded through the Google Cloud service that provides the free dataset as part of the Google Public Cloud Data program.Other download services that were available in SCP 7 (e.g. Sentinel-1, ASTER images) will be available with future updates.

Sean Gillies: Bear training week ~5 recap
sur Planet OSGeoThe 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 OSGeoGli 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.

OGC, UKHO, and partners release the IGIF-(M)SDI Maturity Roadmap
sur Open Geospatial Consortium (OGC)The Open Geospatial Consortium (OGC) is pleased to host and release the first iteration of the IGIF-(M)SDI Maturity Roadmap and supporting materials for community consideration and engagement across not only the marine domain, but any geospatial domain connected to the oceans.
Developed as part of OGC’s ongoing Federated Marine Spatial Data Infrastructure (FMSDI) Initiative, the Integrated Geospatial Information Framework – (Marine) Spatial Data Infrastructure (IGIF-(M)SDI) Maturity Roadmap is a quick-start guide for nations and marine organizations that seeks to advance and simplify efforts in Marine SDI and ensure their alignment with the UN-IGIF principles.
“The IGIF-MSDI maturity roadmap is an important step that supports a holistic understanding of data-exchange and -processing environments,” commented OGC Chief Technology Innovation Officer, Ingo Simonis, Ph.D. “The Roadmap enhances and complements the usual technological focus of SDIs with the equally important criteria outlined in the IGIF Principles. With the Roadmap, OGC continues its engagement and research in support of powerful, sustainable, interoperable geospatial ecosystems at all levels, including technology & standards, policies, communities, education, and capacity building efforts.”
One of the key messages of the document is that an (M)SDI is a continual journey and not an “end state” of expensive technological solutions. The document asserts that nations are sovereign in what manner of (M)SDI they genuinely need for their national requirements, and not governed by an externally imposed or presumed level of technological sophistication.
“Working collaboratively with partners at the World Bank, NOAA, OGC, IHO, and private industry, The UK Hydrographic Office (UKHO) believes that the IGIF-(M)SDI Maturity Roadmap will help many Governments begin their IGIF-aligned digital transformation journeys – whether that be within the Marine or Terrestrial domains,” commented Dr. Gerald J Wong, Data Governance Lead, UKHO.
“As an accessible “Quick Start” or “Stepping Stone” toolkit, the core of the IGIF-(M)SDI Maturity Roadmap is formed by the World Bank SDI Diagnostic Toolkit where, with contributions from IHO and OGC, its Terrestrial heritage was augmented to maximize its benefits to the Marine community. The IGIF-(M)SDI Maturity Roadmap is aligned with the UN-IGIF principles and is fully interoperable with Terrestrial interests.”
When properly executed, the resulting MSDI Diagnostic Toolkit provides a quantitative assessment for nations or marine agencies to baseline their MSDI maturity, as aligned to the UN-IGIF principles. The modular IHO and OGC additions ensure interoperability with the World Bank IGIF methodology, which can lead to the financing of approved MSDI development projects. Even as an independent tool, undertaking an MSDI assessment provides a clear reference point that’s aligned with international Best Practice. Without such a starting point, progress towards any MSDI end state will be difficult to govern and manage.
“As the provider of ADMIRALTY navigation products and services worldwide, the UKHO supports nations in unlocking the many and varied benefits of their marine space,” commented James Carey, Deputy Chief Data Officer at the UKHO “We are a strategic member of the Open Geospatial Consortium and proudly lend our expertise to the development of Marine Spatial Data Infrastructure (MSDI), as an enabler of security, prosperity, and environmental stewardship. By fusing marine data with spatial insights it is possible to forge a path to a more interconnected world where oceans inspire growth and communities prosper.”
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).

Sean Gillies: Bear training week ~6 recap
sur Planet OSGeoFor 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.

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.

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

European Innovation, Global Impact
sur Open Geospatial Consortium (OGC)From Europe to the World, OGC’s Collaborative Solutions and Innovation (COSI) Program is proud of its ongoing contributions to European research topics related to geospatial data. The research topics are driven by projects co-funded by the European Commission (EC) and cover many different domains and fields of application, including data spaces, climate, digital building permits, agriculture, digital twins for the oceans, knowledge generation, and beyond. While these topics are high on the European research agenda, the challenges – as well as their solutions – have global application.
These EC-funded projects are organised as small or large consortiums where different organisations cover different aspects of the projects’ objectives. As one such organisation, OGC is proud to play its part in the European Digital Strategy that is helping to ensure a secure and sustainable life for citizens of Europe and beyond.
OGC’s COSI Program conducts and organises its research around a central theme of “Full Spectrum Interoperability and Agile Reference Architecture.” Full Spectrum Interoperability refers to capturing the many different facets of interoperability that exist between systems. Agile Reference Architecture explores how software architectures can be developed and operated in a cost-efficient, agile, and sustainable manner that also maximises interoperability between systems. This research theme is therefore complementary to the European Digital Strategy.
Much of OGC’s current European work was showcased at the OGC European Innovation Days at Data Week Leipzig 2023. This blog post serves to provide an overview of that work and more for those who couldn’t attend – and who don’t want to have to wait for the next OGC European Innovation Days showcase, to be held July 2024 at FOSS4G Europe in Tartu, Estonia.
Data SpacesStrong progress is being made towards Common European Data Spaces with the projects All Data for Green Deal (AD4GD) and Urban Data Space for Green Deal (USAGE). In both of these projects, OGC is contributing to the development of interoperable, federated systems that support information dissemination and knowledge generation. Such systems will use OGC Standards to enable interoperability at several technical and administrative levels and optimise the value chain that transforms raw data into decision-ready information.
AD4GD’s mission is to co-create and shape the European Green Deal Data Space as an open hub for FAIR (Findable, Accessible, Interoperable, and Reusable) data and standards-based services that support the key priorities of pollution, biodiversity, and climate change. The focus is on interoperability concepts that will bridge the semantic and technology gaps that are currently preventing stakeholders and application domains from accessing multi-disciplinary and multi-scale data. These gaps are also impeding the full exploitation of processing services and processing platforms at different levels, including Cloud, HPC and edge computing. AD4GD recently published this blog post summarising its second plenary meeting, which was co-located with Data Week Leipzig 2023.
The Horizon Europe USAGE project aims to provide solutions and mechanisms for making city-level environmental and climate data FAIR – and thus available to everyone. Leveraging standards for data and service interoperability, such solutions combine innovative governance mechanisms, consolidated arrangements, AI-based tools, and data analytics to streamline the sharing, access, and use of authoritative and crowdsourced city-level Earth Observation (EO) and Internet of Things (IoT) data.
In both of these projects, OGC Standards will play a fundamental part in enabling the resulting FAIR solutions. The main research challenge is developing Building Blocks for common data problems. These Building Blocks bring together data models, examples, code snippets, and schemas, and undergo continuous testing to make them easily accessible and usable by developers, modellers, and users. The goal is to identify and describe common patterns that exist across communities. This will lead to enhanced interoperability within and between data spaces.
Interested in learning more about Data Spaces? OGC will host a session on European common data spaces at the 2023 INSPIRE Conference this November.
ClimateOGC’s current crop of climate-related projects seek to support FAIR climate services and streamline the value chain that transforms raw data into decision-ready information.
Specifically, as part of the Climate Intelligence (CLINT) project, OGC is developing blueprints for transforming scientific algorithms into climate application packages that can be deployed, regardless of their backend, in the Copernicus Climate Change Service (C3S) Climate Data Store (CDS). More widely, the CLINT project seeks to develop Machine Learning (ML) techniques and algorithms that climate scientists can use to process the large climate datasets required for predicting and identifying the causes of extreme events such as heatwaves, warm nights, droughts, and tropical cyclones.
Focusing on the health impacts of climate change, the CLIMOS (Climate Monitoring and Decision Support Framework for Sand Fly-borne Diseases Detection and Mitigation with COst-benefit and Climate-policy MeasureS) project aims to mitigate the emergence, transmission, and spread of pathogens by sand flies. The project is establishing an Early Warning System and decision support tools for more accurate climate and health models. It will also provide predictions of infection risk and spread, as well as adaptation options. OGC is addressing the interoperability challenges faced when combining health, environmental, Earth observation, and climate model data.
Digital Building PermitsOGC is bringing its geospatial expertise to the digitalisation of building permits across two projects: ACCORD and CHEK. Albeit with a different focus, both projects aim to transform what is currently a largely manual process into a semi-automated one that allows building applications to be submitted in digital form.
In support of sustainability and resource conservation, the ACCORD (Automated Compliance Checks for Construction, Renovation, or Demolition works) has a strong focus on regulations analysis and the use of ontologies and linked data to automate the compliance checks. ACCORD will develop a semantic framework for European digital building permit processes, regulations, data, and tools. This framework will drive the formalisation of rules and the integration of existing compliance tools as Standards-based microservices, for example using OGC APIs. The solutions and tools being developed by ACCORD will provide consistency, interoperability, and reliability with national regulatory frameworks, processes, and standards.
The CHEK (Change toolkit for digital building permit) project is looking at the entire workflow for the digitalisation of building permits and is facilitating the introduction of digital building permit procedures for municipalities by developing flexible, adaptable solutions that take into account all the rules and conditions of the procedure. As with ACCORD, CHEK is using a Standards-based microservices approach to its architecture. CHEK will also develop training for municipalities, which will be made available through the Location Innovation Academy (see below).
As part of CHEK, OGC is investigating how needs-based data models can be derived dynamically as profiles of common conceptual models. The goal is to leave behind the basic problems of standardised data models. Due to their ambition to comprehensively represent a domain, they tend to be over-specified. On the other hand, to adapt to the needs of different use cases, they allow too much flexibility in implementation and modelling details. OGC is currently focused mostly on the transformation of administrative data using ontologies generated from CityGML and CityJSON.
AgricultureThe DEMETER project, which is now coming to an end, has helped to digitally transform Europe’s agri-food sector. DEMTER adopted advanced IoT technologies, data science, and smart farming to ensure the long-term viability and sustainability of the agriculture sector. One of the key results is the production of an Agriculture Information Model (AIM). The AIM is a data model and ontology for agriculture applications that ensures semantic interoperability between data and components involved in agri-food applications. To further enhance the AIM, OGC has now formed the Agriculture Information Model Standards Working Group (AIM SWG). The OGC AIM will provide a common language for agriculture applications to harmonise and improve data and metadata exchange by defining the required data elements, including concepts, properties, and relationships relevant to agriculture applications, as well as their associated semantics/meaning for information exchange.
Oceans and the Blue EconomyThe Iliad Digital Twins of the Ocean project is developing a federated, multidimensional representation of the maritime and oceanic ecosystem. As with many of these projects, OGC Standards will be used to enhance the value chain as data sourced from smart IoT, satellite Earth Observations, and Citizen Science is transformed into decision-ready information and knowledge. As such, it fits perfectly into the OGC focus theme of “marine spaces.”
Iliad is developing several Digital Twin pilots in a number of key areas, including: wind energy; renewable energy from the ocean (currents, waves & floating solar); fisheries & aquaculture; marine traffic & harbour safety; pollution; met ocean data (hind, now & forecasts); biodiversity assessments & monitoring; and insurance for marine & maritime activities.
OGC is involved in defining the standards-based Data Transfer Object (DTO) data management APIs built on the OGC APIs framework, as well as ensuring semantic interoperability between the APIs, Citizen Science, and thematic domains. Finally, we are leading standardisation and best practice tasks to enable the solution to fit within the ecosystem of the Digital Twin of the Earth.
Location Innovation AcademyThe recently launched Location Innovation Academy is a free online training program based on the knowledge and ideas generated by the GeoE3 project. The free online academy empowers users to improve the accessibility, interoperability, and integration of their geospatial data and services. The academy is currently targeted towards national mapping agencies, meteorological institutions, and other organisations producing or using geospatial data from different countries. The Academy aims to help overcome the interoperability gaps that still exist between European countries.
The growing online training package currently includes three different courses for developing skills in: Data Management; Service Management; and Data and Service Integration.
The Location Innovation Academy also serves as the experimentation platform for a future OGC Academy that will help learners access and exploit the enormous amounts of knowledge generated by OGC. The Location Innovation Academy is hosted by OGC at academy.ogc.org. In support of the academy, OGC is also a Pact For Skills Member.
The Academy continues to be the main component of the DIS4SME project. DIS4SME aims to provide SMEs with high quality specialised training courses on data interoperability across different areas, including location data.
By Europe, for the WorldAs a participant in projects funded by the European Commission, OGC’s COSI Program – with its complementary research theme of “Full Spectrum Interoperability and Agile Reference Architecture” – is proud to develop valuable solutions that support the European Digital Strategy and help ensure a secure and sustainable life for not only the citizens of Europe, but the entire world.
The next OGC European Innovation Days showcase will be held July 2024 at FOSS4G Europe in Tartu, Estonia.
OGC is also hosting a session on European common data spaces at the 2023 INSPIRE Conference this November.

OGC API – Environmental Data Retrieval v1.1 Adopted as Official Standard
sur Open Geospatial Consortium (OGC)The Open Geospatial Consortium (OGC) is excited to announce that version 1.1 of the OGC API – Environmental Data Retrieval (EDR) Standard has been approved by the OGC Membership for adoption as an official Standard.
The Standard is part of the OGC API family of Standards that each help advance OGC’s Mission to make the world’s location information FAIR: Findable, Accessible, Interoperable, and Reusable.
The OGC API – EDR Standard makes it easy to access a wide range of data through a uniform, well-defined, simple Web interface that provides users with purely the data they require while shielding them from the complexities of the underlying data storage technologies.
A major use case for an EDR API is to retrieve small subsets from large collections of environmental data, such as weather forecasts, though many other types of data can be accessed. The important aspect is that the data can be unambiguously specified by spatio-temporal coordinates.
The Standard describes a series of requirements for developing an EDR API, including lightweight query interfaces that allow users to request spatio-temporal data at a specific Position, within a Radius, within a Cube, within an Area, along a Trajectory, or through a Corridor.
Version 1.1 of the Standard offers a number of backwards-compatible enhancements. One major enhancement is support for the HTTP POST method. This enhancement will make it possible to handle requests with large payloads, such as complex filter constraints. Another enhancement is greater flexibility in selecting a default Coordinate Reference System (CRS) to be used when a client application has not indicated a preferred CRS. This enhancement will make it easier to serve data that is referenced to national or regional coordinate reference systems.
The other major enhancement is support for additional custom or categorical dimensions to use in queries in addition to the usual (x,y,z,t) continuous spatio-temporal dimensions. An example use case would be to request data for a specific wavelength or select from a specific waveband. A common meteorological use case would be to query data from a specific forecast from an ensemble of simultaneous forecasts.
The OGC API – EDR Standard supports a full range of use cases: from retrieving time-series observations to sub-setting multi-dimensional data cubes along user-supplied sampling geometries. Such sampling geometries are provided by a client through query patterns that use a set of common parameters. These query patterns provide useful building blocks to allow the composition of APIs that satisfy a wide range of geospatial data use cases. By defining a small set of query patterns, the OGC API – EDR Standard helps to simplify the design of systems, as they can be performance tuned for the supported queries – thus making it easier to build robust and scalable infrastructure.
To help users implement the OGC API – EDR Standard, an OpenAPI definition document and schema definition files have been published, alongside the Standard, on the OGC API – EDR page.
To learn more about how the family of OGC API Standards work together to provide modular “building blocks for location” that address both simple and the most complex use-cases, visit ogcapi.org.
OGC Members interested in staying up to date on further progress of this standard, or contributing to its future development, are encouraged to join the OGC API – EDR 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 OGC API – Environmental Data Retrieval 1.1 Standard is free to download and implement. Interested parties can view and download the Standard from the OGC API – EDR page.

With its OGC Rainbow, OGC is building the most advanced interoperability framework in the geospatial domain. OGC Rainbow connects taxonomies, profiles, Standards, schemas, metadata, and other elements and enables reliable knowledge generation and decision making, all in a machine- and human-friendly environment.
Dr. Simon Cox will help OGC to further develop the conceptual model behind OGC Rainbow and review all of the underlying assumptions and use cases. Simon will also play a critical role in communicating and coordinating OGC Rainbow with other standards organizations.
“I am excited that Simon will join our work to enhance the level of interoperability seen in the geospatial domain,” said OGC Chief Technology Innovation Officer, Dr. Ingo Simonis. “Simon has excellent expertise in data modeling and extracting modeling patterns and mechanisms. I am confident that Simon will help us take the work around our ‘OGC Rainbow’ interoperability environment to the next level.”
Dr. Simon Cox worked for many years for the leading Australian science and technology organization, CSIRO. Simon has been involved in OGC activities since the year 2000, and received an OGC Gardel’s Award in 2006. Recently, Simon made substantial contributions to the joint OGC/W3C efforts on spatial data on the web.
Simon was the primary driving force behind the creation of the initial resources upon which OGC Rainbow has been built and led the establishment of the OGC Naming Authority – the group that governs OGC’s registries and Standards schemas. After retiring from CSIRO earlier this year, he has maintained an involvement in vocabulary management and publication, and in cross-domain metadata through CODATA and DDI.
“I’m looking forward to renewing my engagement with OGC,” said Simon. “I’ll bring perspectives from recent engagements in environmental and social sciences where adaptation of OGC and W3C standards to specific applications, and presentation of that to a variety of audiences, remains a challenge.”
OGC’s Visiting Fellow program was established to support OGC’s integrated standards and innovation strategy, which falls under the leadership of OGC’s Chief Standards Officer, Scott Simmons, and Chief Technology and Innovation Officer, Dr. Ingo Simonis. The program welcomes highly accomplished, seasoned experts from around the world to augment OGC’s leadership team with external targeted expertise and support the strategic objectives of the Consortium for durations of 3-9 months.
If you are interested in the OGC Visiting Fellow program and wish to be considered, please contact OGC using the form at ogc.org/contact.

Jackie Ng: Where's the new Maestro API nuget packages?
sur Planet OSGeoThere 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.

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

Sean Gillies: Never Summer training weekend recap
sur Planet OSGeoThursday, 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.
American Lakes basin from Thunder Pass
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.

Sean Gillies: Laid off
sur Planet OSGeoMy 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.

Jackie Ng: Announcing: MapGuide Maestro 6.0m12
sur Planet OSGeoNext stop on the tour: A new release of MapGuide Maestro
This release includes the following notable changes.
Improved MapGuide Open Source 4.0 authoring supportThis 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 featuresThis 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.

Developers invited to the 2023 OGC API – Processes Virtual Code Sprint
sur Open Geospatial Consortium (OGC)The Open Geospatial Consortium (OGC) invites developers to the 2023 OGC API – Processes Virtual Code Sprint to be held September 18-20, 2023, on Gitter. Registration for the code sprint is free and open to the public.
The Sprint will focus on refining the next version of the OGC API – Processes Standard and associated extensions.
The OGC API – Processes Standard supports the wrapping of computational tasks into executable processes that can be offered by a server through a Web API and be invoked by a client application. Typically, these processes combine raster, vector, coverage, and/or point cloud data with well-defined algorithms to produce new information.
Examples of computational processes that can be supported by implementations of OGC API – Processes include vector data analysis, imagery analysis, and various types of Artificial Intelligence (AI) enhanced analysis.
An OGC Sprint is a collaborative and inclusive event driven by innovative and rapid programming with minimal process and organization constraints to support the development of new applications and candidate standards.
During the virtual code sprint, there will be an opportunity for joint discussion with all participants on the goals and objectives of the event, as well as the final briefing of findings and opinions of the participants. However, the majority of the time will be spent in collaboration between participants in active coding. The virtual code sprint will run from 9:00am to 5:30pm US Eastern Time each day.
To learn more about how the family of OGC API Standards work together to provide modular “building blocks for location” that address both simple and the most complex use-cases, visit ogcapi.org.
Registration for the 2023 OGC API – Processes Virtual Code Sprint is here. The Sprint will take place in the ogc-developer/Sprints Gitter room from 9:00am to 5:30pm (US Eastern) each day from September 18-20, 2023.

OGC adopts CityGML 3.0 Part 2: GML Encoding as an official OGC Standard
sur Open Geospatial Consortium (OGC)The Open Geospatial Consortium (OGC) is excited to announce that the OGC Membership have approved the OGC City Geography Markup Language (CityGML) Part 2: GML Encoding Standard for adoption as an official OGC Standard.
The CityGML 3.0 GML Encoding Standard presents the GML encoding of the concepts defined by the CityGML 3.0 Part 1: Conceptual Model (CM) Standard, which was approved as an OGC Standard in 2021. The GML encoding is compliant to OGC GML versions 3.2 and 3.3 (thus also ISO 19136). This encoding can be used to store and exchange 3D city models in the GML format as data sets or via web services.
Since its first publication by OGC in 2008, CityGML has been an open standard used for the storage and exchange of virtual 3D city models. CityGML allows the integration of urban geodata for use across a variety of applications, including urban and landscape planning; Urban Digital Twins for Smart Cities; the Metaverse; Building Information Modeling (BIM); mobile telecommunication; disaster management; 3D cadastre; tourism; vehicle & pedestrian navigation; autonomous driving and driving assistance; facility management; and energy, traffic, and environmental simulations.
CityGML defines a “City” in a broad fashion to comprise not just built structures, but also the land surface, vegetation, water bodies, city furniture, and more. Despite its name, CityGML is useful for large areas and small regions, not just cities, and can represent real-world terrain and 3D objects at different Levels Of Detail (LOD) simultaneously. CityGML enables the consistent representation of 3D urban objects across different Geographic Information Systems and users.
CityGML 3.0 is an evolution of the previous versions 1.0 and 2.0 of CityGML that further enables the cost-effective sustainable maintenance of 3D city models. While previous versions standardized a GML exchange format, CityGML 3.0 standardizes the underlying information model and can thus be implemented in a variety of technologies beyond GML. As a result, governments and companies can increase the Return On Investment (ROI) of their 3D city models by being able to put the same models into play across different technology platforms and application fields.
This Part 2 of the Standard defines how the concepts developed in Part 1 are realized using XML and GML technologies. The CityGML 3.0 GML encoding represents a full mapping of the Conceptual Model. The encoding is derived fully automatically from the UML model following the UML-to-GML encoding rules as defined by ISO 19136.
A collection of example data sets for the CityGML 3.0 GML Encoding is available from the OGC CityGML-3.0 Encodings Public GitHub Repository.
OGC Members interested in staying up to date on the progress of this standard, or contributing to its future development, are encouraged to join the CityGML Standards Working Group (SWG) 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 CityGML Part 2: GML Encoding Standard is free to download and implement. Interested parties can learn more about, view, and download the Standard from OGC’s CityGML Standard Page.

sur Planet OSGeoIn 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!

Volker Mische: FOSS4G 2023
sur Planet OSGeoFinally, 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 venueWow. 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 talksI 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 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 learntThe 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 thoughtsIt 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.

CharlasImplementación de Geoportales Estadísticos en América Latina y el Caribe
A partir de la implementación del Marco Geoespacial y Estadístico Global (GSGF) propuesto por la ONU e implementado en América Latina y el Caribe por la Comisión Económica para América Latina y el Caribe (CEPAL), se desarrollaron un conjunto de componentes tecnológicos específicos, tales como geoportal, gestor estadístico y API con posibilidad de consumir información de diferentes aplicaciones. Al mismo tiempo, se implementaron componentes ya existentes en la comunidad como Kobo Toolbox, GeoNode, Airflow, MapLibre, Nominatim y Metabase para la integración de la información desde la recolección en el territorio hasta la publicación de los datos. El proyecto se realizó inicialmente con un grupo de países: Argentina, Paraguay, Honduras, Guatemala, República Dominicana, Costa Rica y Ecuador.
[Caso de uso] Implementación Digital Twin City en MapLibre con la integración de diferentes fuentes de información
Caso de uso para la implementación de una plataforma que soporte datos que contribuyan a la publicación y gestión de Gemelos Digitales, basada en el uso de MapLibre como visor web y al mismo tiempo consumiendo información de diferentes fuentes geoespaciales, incluyendo Mesh, Raster, DEM y fuentes de datos casi en tiempo real como OneBusWay u OpenTripPlanner basadas en formatos GTFS, para la comparación y análisis de la información.
[Caso de uso] Automatización de Kobo Toolbox con GeoNode para la gestión de riesgos
A partir de la implementación de un conjunto de formularios en Kobo Toolbox se creó un flujo de información para la Comisión de Manejo de Incendios de la República Argentina para poder integrar desde campo los reportes de incendios (on line/off line) de manera sencilla y sus diferentes etapas de evolución. La automatización de la ingesta a un GeoNode como gestor de datos geoespaciales permite la integración con datos de previsión meteorológica, información casi en tiempo real, incidencias de incendios, detección de puntos calientes e índices predictivos de incendios.
La automatización e integración se realiza con la herramienta Airflow, que garantiza el seguimiento de los flujos de información, simplificando el proceso durante las incidencias.

Jackie Ng: Announcing: mapguide-react-layout 0.14.9
sur Planet OSGeoOur journey needed to make a temporary detour, with another release of mapguide-react-layout.
This release has the following notable changes
Legend layer and group customization supportThis release provides a new viewer init option to allow layer and group elements of the Legend component to be augmented with additional HTML content. For example, we can use this to add a download link for specific layers (how to actually implement the download link is an exercise left to you the reader)
See this comment for an example of how to customize the layer and group elements.Reduced excessive re-renderingIn the process of implementing the above feature, we discovered that some components (the Legend component in particular) did a lot of pointless re-rendering which contributes to sluggishness in viewer performance.
For this release, great efforts were made to ensure that component re-rendering is the result of legitimate changes to component state and not from pointless re-rendering from bogus shallow state "changes"
Removed IE-specific polyfills and workaroundsInternet Explorer ceased to be a supported browser by Microsoft for some time now. This release formally removes our various IE-specific workarounds and polyfills that were only there to support this ancient browser.
Other changes- The urlPropsIgnore setting is now considered when the viewer updates the URL state
- The viewer bundle patches OpenLayers to log a console warning and abort rendering when attempting to render a map overlay image with a width/height/scale/dpi of 0
- Fixed an issue where no map images are rendered if the browser zoom is below 100%

Ian Turton's Blog: How much fun was FOSS4g 2023?
sur Planet OSGeoReview of FOSS4G 2023 IntroductionFOSS4G 2023 was held in Prizren, Kosovo and there were 800+ attendees from 120+ countries. This was a great attendance despite Kosovo not being the easiest place to get to, especially if you were me. I had booked flights to and from Belgrade, Serbia because they were a relatively good times for me (I am missing being only 1 hour from a London airport). It looked like an easy 4 hour drive from the airport to Prizren. Then about a fortnight before the conference Kosovo closed it border to Serbian registered cars! A subsequent check all showed that most of the hire companies wouldn’t let you drive one of their cars over a border (and apparently despite the Serbian Government’s claims they considered Kosovo a separate country). So I fell back on the 9 hour overnight bus trip, which wasn’t as bad as it could have been but did mean I started the conference already somewhat sleep deprived.
Sort of Historical Side NoteWhen I was at school learning Geography all of this area was called Yugoslavia and it was behind an “iron curtain” so we knew little about it and cared even less (it was not on the exam). In history it was covered by the break up of the Ottoman Empire and the meddling of Bismarck as an “honest broker” at the 1878 Congress of Berlin (as I recall he rigged the Balkans in such a way as to start World War I, but history O-Level was a long time ago). So you can already see that there is a long a complex history and geography in the region. It became more complex in the 1990s when Yugoslavia broke up in a series of bloody conflicts, which I remember from the evening news. Kosovo only really came to my attention in 2008 when I was walking through New York with James Macgill and his kids and we saw a large group of cars flying large red flags with double headed eagles on them (and the one thing I retained from my history lessons is the ability to spot a double headed eagle at 200 metres). These were Kosovans celebrating the declaration of independence being proclaimed.
So squabbling about car number plates was pretty peaceful really. Fortunately, for us most of KFOR (the UN/Nato peace keeping force) had gone home, except for some in the Northern predominately Serb areas where they were out keeping the piece over disputed elections for city mayors. This meant we could use their old base as a conference venue, which was great except for the lack of lifts.
Cool talksThis is a list of talks I found particularly interesting or fun and that stuck in my mind long enough to remember for this post. There were lots of great talks that I either failed to see because the room was too full or was too hot for my brain to have taken in the details, so I’m looking forward to the videos coming out so I can refresh my memory later.
- Neiene Boeijen Let’s put it on the map!

learning JavaScript or WebGL but the demo with 10,000 randomly coloured bouncing map markers is fun in a
