Satellite intelligence without the complexity.

ESA's Sentinel-1 radar satellites image the entire Earth for free. We process it and serve it via a clean REST API.

Flood detection

Identify flooded areas from SAR backscatter changes. Returns polygon GeoJSON with area estimates and confidence scores.

Vessel detection

Detect ships at sea using radar cross-section analysis. Returns point GeoJSON with length estimates — works through clouds.

Change detection

Compare two passes to find construction, deforestation, or surface changes. Returns changed polygons with before/after timestamps.

Clean GeoJSON

Every result is standard GeoJSON with confidence scores and metadata. Drop straight into Mapbox, Leaflet, or any GIS tool.

Spatial queries

Query by bounding box. Results are spatially indexed with PostGIS — fast range lookups over large AOIs.
