Have you been wondering what this Zarr thing is all about and how it works? Then there's the whole Kerchunk/VirtualiZarr indexing to get cloud-native access for non-cloud-native data formats, what's that about? Cloud-native geospatial is all the rage these days, and for good reason. As data sizes grow, layer counts increase, and analytical methods become more complex, the traditional download-to-the-desktop approach is often untenable. It's no surprise then that users are turning to cloud-native tools to scale out their analyses. But as we transition away from opening whole files to now grabbing ranges of bytes off remote servers it seems all the more important to understand exactly how cloud native data formats actually store data and what tools are doing to access it. This workshop aims to dig into how cloud-native geospatial data formats are enabling new operational paradigms, with a focus on raster formats. We'll start by surveying the current cloud-native geospatial landscape to understand the importance of cloud native and how it is being used, including the core tenants of cloud-native, common formats, and how things like SpatioTemporal Asset Catalogs (STAC) and STAC-based tooling integrate to provide more efficient access paradigms. Then we'll get hands-on to build up an understanding of how these formats work at a deep level. We'll extract a tile from a COG by hand, then try the same with Zarr data to see how those formats compare. Lastly, we'll look at Kerchunk/VirtualiZarr and see how these allow optimized data access for non-cloud-native formats. false https://talks.osgeo.org/foss4g-2026-workshop/talk/MPR9BD/ https://talks.osgeo.org/foss4g-2026-workshop/talk/MPR9BD/feedback/ 601 Workshop 2026-08-30T14:00:00+09:00 14:00 03:00 A hands-on workshop on cloud-native raster analytics using open standards and scalable Python tools.

Traditional file-based GIS workflows struggle when working with large raster collections, global time series, or multi-band imagery. This hands-on workshop introduces a practical, open-source workflow for scalable raster analytics using STAC, Cloud-Optimized GeoTIFF (COG), xarray, rioxarray, and Dask. Participants will: - Discover satellite imagery from public STAC catalogs - Stream raster data directly from the cloud without downloading entire scenes - Structure multi-temporal imagery into a labeled data cube - Perform scalable computations using chunked, parallel processing - Generate derived products such as vegetation indices and temporal summaries Workshop materials, including content, notes, and code examples, are available at: https://amanchry.github.io/scalable-raster-analytics/ false https://talks.osgeo.org/foss4g-2026-workshop/talk/STWUHW/ https://talks.osgeo.org/foss4g-2026-workshop/talk/STWUHW/feedback/ 603 Workshop 2026-08-30T10:00:00+09:00 10:00 03:00 This workshop is aimed at helping experienced QGIS users discover PostGIS. You’ll become familiar with using database connections, tables & views, relational modeling, spatial SQL, and dynamic views to build smarter, faster, and more scalable GIS workflows directly within the familiar QGIS interface. foss4g-2026-workshop-5517-discovering-postgis-an-introduction-for-qgis-users Federica GaspariJohn Bryant en We will bridge the gap between traditional desktop GIS and enterprise data management by turning your PostGIS database into the engine of your QGIS projects. The session skips the basic "how to add a layer" and dives straight into the features that matter for optimised workflows. Some topics we’ll cover: - Create and edit tables directly from the QGIS interface - Write views, "magic layers" that join multiple tables, spatially transform/analyse/aggregate your raw data, and automatically update from upstream tables - Store projects and styles directly in the database for a seamless experience - Relational tables: setting up 1:N and M:N relationships at the database level and using them in QGIS - Data integrity and validation: use constraints and schemas to keep your data valid, clean, and organized This is an introductory PostGIS workshop for users looking for a learning journey from a QGIS perspective. We’ll use the DB Manager and Browser to interact with SQL, ensuring that the database feels like a natural extension of your existing workspace rather than an intimidating command-line tool. Participants will leave with a solid idea for building optimised high-performance GIS environments. false https://talks.osgeo.org/foss4g-2026-workshop/talk/SSQZQ3/ https://talks.osgeo.org/foss4g-2026-workshop/talk/SSQZQ3/feedback/ 603 Workshop 2026-08-30T14:00:00+09:00 14:00 03:00 Going beyond all the common functions that most folks use PostGIS for. Delving into advanced use cases and using PostGIS in production workloads. foss4g-2026-workshop-5085-advanced-postgis-beyond-the-basics Rhys Stewart en PostGIS, sitting on top of Postgresql, is by most metrics, the most popular spatial database. Many videos are online about how to install and use PostGIS....many are from prior FOSS4G conferences and do a good job in getting you to understand the basics. Most of them, however, only scratch the surface when it comes to the power that can be wielded with PostGIS. This workshop seeks to explore a wide array of functions that may be used on a regular basis or are outside the scope of common spatial queries.. These include, but are not limited to: - Linear Referencing - Clustering - Rasters analytics - Vector Tiles There will also be an emphasis on exposing PostGIS data and functions to the web, to this end, there will be some usage of other software products (for example: Martin Vector tile server or pg_featureserv or pg_tileserv or PostgREST).

Teams building production Earth observation platforms repeatedly solve the same problems from scratch. This hands-on workshop provides a complete, end-to-end walkthrough of building a production-ready STAC API using eoAPI ([`pgSTAC`](https://stac-utils.github.io/pgstac/) + [`stac-fastapi-pgstac`](https://stac-utils.github.io/stac-fastapi-pgstac/)) and securing it with [`stac-auth-proxy`](https://developmentseed.org/stac-auth-proxy), a backend-agnostic reverse proxy purpose-built for STAC. Starting from a bare Docker Compose stack running entirely on participants' laptops, we'll ingest real Earth observation datasets and then query the catalog using CQL2 filters and spatial search. From there, we'll progressively layer in authentication using OpenID Connect (OIDC), connecting a local mock identity server to the proxy, locking down write endpoints behind token-scoped access control, and protecting the Transactions Extension so only authorized clients can modify the catalog. The penultimate section tackles row-level authorization: using CQL2 filter injection to build public/private collection support and multi-tenant data isolation, where each user's JWT claims determine what slice of the catalog they can see, all without modifying the underlying API. We close by connecting [STAC Browser](https://github.com/radiantearth/stac-browser) to the secured API, configuring its OAuth2/OIDC settings to authenticate against the mock identity server, and demonstrating how the auth policies built throughout the workshop shape what different users can discover in real time. Participants will leave with a working local stack, reusable configuration patterns, and a clear mental model for applying these techniques in cloud deployments. false https://talks.osgeo.org/foss4g-2026-workshop/talk/TGNSY7/ https://talks.osgeo.org/foss4g-2026-workshop/talk/TGNSY7/feedback/ 605 Workshop 2026-08-30T14:00:00+09:00 14:00 03:00 Attendees will build two complementary approaches for enabling geospatial awareness in LLMs: Geo-GraphRAGs for analyzing networks of features and DGGS-based methods for integrating aggregate and statistical data, and how they work together. foss4g-2026-workshop-5550-building-geospatially-aware-llm-agents-with-spatial-knowledge-graphs-and-discrete-global-grid-systems Nathan McEachen en LLMs lack intrinsic geospatial awareness and do not maintain structured knowledge of geographic features or their domain-specific relationships. As a result, they cannot reason about how disruptions propagate through interconnected spatial systems—such as transportation networks, health service accessibility, or school catchments—during events like floods, wildfires, or other natural hazards. While LLMs excel at synthesizing text, they lack an internal representation of spatial networks and semantic relationships required for geospatial reasoning. In this hands-on workshop, participants will build a geospatially aware LLM application from the ground up using open-source tools. You will create a Spatial Knowledge Graph (SKG) using Apache Jena to model networks of geographic features and their relationships, and use it to develop a Geo-GraphRAG pipeline that enables LLMs to translate natural-language questions into GeoSPARQL queries—providing transparent, traceable answers grounded in real data. You will also learn how Discrete Global Grid Systems (DGGS)—an emerging Open Geospatial Consortium (OGC) standard—enable integration of aggregate and statistical data across domains by aligning datasets to a common spatial reference. Using open-source DGGS tooling such as DGGAL, participants will build an LLM agent capable of generating both GeoSPARQL queries over feature networks and DGGS API calls using CQL2, and explore how semantic feature networks relate to DGGS zones. By the end of the session, you will understand how graphs and grid systems work together to unlock geospatial reasoning in AI systems.

Representing and processing these “moving features” in a scalable and interoperable way is a key challenge for developers building next-generation location-based services. This workshop introduces OGC API–Moving Features (OGC API–MF), an open standard designed to handle spatiotemporal data in a consistent, developer-friendly manner. Participants will learn how to manage, query, and analyze moving feature data using standardized APIs that support filtering, sorting, and aggregation across space and time. Going beyond static APIs, we will also explore the next-generation streaming extension of OGC API–MF. Using Apache Kafka and ksqlDB, we demonstrate how to build a real-time pipeline for ingesting, processing, and tracking moving objects—bridging the gap between standard-based data models and event-driven architectures. This is a hands-on, end-to-end session where you will: - Understand the core concepts of OGC API–MF and MF-JSON - Deploy a fully functional API using pygeoapi - Store and query trajectory data with MobilityDB / PyMEOS - Validate implementations with test code - Visualize spatiotemporal data using STINUUM (Cesium-based client) All components are containerized with Docker, enabling quick setup and reproducible experimentation.

This workshop takes participants from first contact to working code in three hours. We start in the Copernicus Browser — exploring satellite imagery and derived products interactively. Once oriented, we look at what's available: over 100 analysis-ready collections — most of them global. Then we get to the core: evalscripts — custom JavaScript-like functions that run server-side on CDSE's infrastructure, executing per-pixel across entire satellite scenes. We explain the format, write one by hand, and run it in the browser. We bring in AI coding assistants. For example, a cumulative temperature threshold that tells farmers when to plant — typed into an AI as a plain-language description, returned as a working evalscript. No remote sensing background needed. Participants try the same: describe a measurement, generate an evalscript, debug and iterate until it works on real data. Finally, we demonstrate programmatic access using sentinelhub-py. The same evalscripts, now running at scale from a Python notebook.

While open-source GIS tools have matured significantly, many real-world problems now exceed the limits of desktop-based processing. This workshop introduces High-Performance Computing (HPC) as a natural extension of modern GIS, not as a replacement. Using flood and environmental modeling as core examples, the session demonstrates where traditional GIS workflows struggle and how parallel and distributed computing can unlock new possibilities using fully open-source tools. Participants will learn HPC concepts through familiar GIS analogies and see how tools like QGIS, GDAL, Python, Dask, and ANUGA Hydro can be integrated with HPC systems. Through live demonstrations and guided workflows, the workshop shows how large raster processing, time-stepped simulations, and spatio-temporal analytics can scale efficiently on HPC infrastructure. The workshop emphasizes practical adoption, showing how GIS users can continue working in their existing open-source ecosystem while leveraging HPC for heavy computation.

Despite the well-understood tools and technologies, such as cloud-optimised GeoTIFFs (COG) and the Spatio-Temporal Asset Catalog (STAC) and STAC API specifications, many EO professionals have not yet had the opportunity to practically apply these innovations. This workshop aims to bridge that gap by showcasing how cloud-native geospatial technologies simplify the process of working with EO data, using Python as the primary programming language. In part one of the workshop, we’ll talk about Al Gore’s vision for a digital Earth, and how we’re on the path to realising that vision, before we get hands-on coding a Earth observation data science notebook from scratch, loading and visualising Landsat data.

As data sizes grow, layer counts increase, and analytical methods become more complex, the traditional download-to-the-desktop approach is often becoming untenable. It's no surprise then that users are turning to cloud-based tools to scale their analyses. But as we transition away from opening whole files to now grabbing ranges of bytes off remote servers it seems all the more important to understand exactly how cloud-native data formats actually store data and what tools are doing to access it. This workshop aims to dig into how cloud-native geospatial data formats are enabling new operational paradigms, with a particular focus on (Geo)Parquet. Participants do not need an existing familiarity: we'll work together to develop a understanding of the concepts behind Parquet, starting with GeoJSON, roughly as follows: * GeoJSON: what is it, what does it represent, and how it is not cloud-native * Well-Known Text/Binary (WKT/WKB): how these vector formats work and why they are important in (Geo)Parquet * (Geo)Parquet: how does parquet store data, how geo maps into that paradigm, and what it takes to read some subset of data from a parquet table The content of this workshop aims to be not only theoretical but practical: a strong goal is to be as hands-on with these formats in Python. We'll eschew common tools, opting to take a more manual approach. An educationally-focused Parquet library will provide a view into the process of reading Parquet files, their metadata, and techniques used to performantly run queries.

Each exercise is inspired by real prompts from the #30DayMapChallenge (e.g., Points, Accessibility, Minimal map, Projections, Raster, Makeover), encouraging participants to explore a wide range of themes, data types, and visual approaches. Rather than producing a single polished output, participants rapidly iterate across multiple maps, each emphasizing a specific design principle such as visual hierarchy, color, classification, annotation, or narrative focus. The goal is to build fluency in making clear, intentional design decisions under time constraints. Prompts are paired with lightweight constraints (e.g., “one message only,” “design for accessibility,” “show uncertainty,” “reduce clutter”) to encourage experimentation without overthinking or overengineering. A mix of free and open source tools will be used, with templates and prepared datasets provided to keep the focus on design rather than setup. Ethical considerations are embedded throughout, including visual honesty, representation, accessibility, risk of misinterpretation and how even small design choices can shape meaning.

Kiro will write all of the python code for the server and will interactively test it as we create each new tool. false https://talks.osgeo.org/foss4g-2026-workshop/talk/NQLMNG/ https://talks.osgeo.org/foss4g-2026-workshop/talk/NQLMNG/feedback/ 101 Workshop 2026-08-31T14:00:00+09:00 14:00 03:00 Configure and deploy geospatial datasets, API, and web mapping interfaces in the cloud for free using GEOLYTIX XYZ/MAPP. Spatial data will be stored in a neon.tech cloud database. The service will be deployed to serverless function via Vercel. The configuration can is managed via Github Codespaces. foss4g-2026-workshop-5237-web-mapping-with-xyz-codespaces Dennis Bauszus en This hands-on workshop will guide participants through the configuration of an XYZ/MAPP application as an interface for spatial data which will be hosted in a PostGIS database. The configuration of the web mapping application can be completed with GitHub Codespaces in the browser - no installs on the developer machine are required! The finished application will allow users to digitise locations in the browser and upload images stored in Cloudinary. The location geometries and properties will be stored in a cloud hosted Neon PostGIS database. The application will deployed from Codespaces as serverless function to Vercel. false https://talks.osgeo.org/foss4g-2026-workshop/talk/97XXJ3/ https://talks.osgeo.org/foss4g-2026-workshop/talk/97XXJ3/feedback/
