GIS development
- Custom layers, attribute schemas and review workflows built on top of your workspace
- PostGIS-backed storage with a declared CRS for every layer
- Import from Shapefile, File Geodatabase, GeoJSON or GeoParquet
Layer · county_parcels

Satellite imagery processing
- STAC search across Sentinel-2 L1C / L2A and Landsat 8/9 collections
- Cloud and shadow masking, clipping and mosaicking per AOI
- Outputs written as Cloud Optimized GeoTIFF with overviews
