Derek Young, David Russell; Pre-Conference Workshop
Use recently developed Open Forest Observatory tools to process forest imagery from low-cost drones into tree-level maps, including species predictions from computer vision applied to raw drone images, and evaluate results against ground reference data.
Corey White; Pre-Conference Workshop
Repeat lidar and photogrammetry reveal how geohazards reshape terrain, but raster differencing may confuse noise with real change. In this hands-on workshop, emergency managers and analysts build robust, uncertainty-aware change detection workflows in GRASS using Hurricane Helene data.
GUILLAUME SUEUR; Pre-Conference Workshop
Hazard datasets are critical and exhausting to work with: shapefiles, oversized polygons, per county distribution. This workshop walks through a pattern that turns this kind of data into a clean, query-optimized GeoParquet asset — using DuckDB, Python, and object storage.
Pratyush Kumar Das; Pre-Conference Workshop
End "dependency hell" in geospatial projects. This hands-on workshop introduces the Nix package manager to build deterministic, immutable development environments. Learn to version-control your entire software stack to ensure perfect reproducibility across local, cloud, and production infrastructure.
JJ Paul; Pre-Conference Workshop
Current commodity flow datasets are highly aggregated, limiting local analysis. This workshop teaches open disaggregation methods so participants can generate county- and commodity-level estimates from coarse data using transparent, reproducible workflows.
Michele Tobias; Pre-Conference Workshop
Learn design principles to make maps that communicate well. This workshop is divided into two sections. The first covers concepts and approaches to designing maps. The second will provide hands-on experience making a map in QGIS.
Vishal Kumar, Shaishav Mahendrakumar Maisuria; Pre-Conference Workshop
Build a wildfire-evacuation map for a Sacramento-area community, then compute its routes to safety, all on your laptop. One open pipeline runs from DuckDB and Overture through Planetiler tiles and MapLibre to live OSRM routing.
Dewey Dunnington; Pre-Conference Workshop
Learn how analytical databases make the most of your laptop to make existing workflows faster and larger workflows possible using SedonaDB, a database built for spatial from the ground up.
