ComputationalAPIs
Under DevelopmentIntegrate planetary computations directly into your applications. Query rasters, execute band algebra, and analyze terrains programmatically.
Platform API Services
The VELSTROM API provides high-speed, geo-spatial calculation layers. By defining coordinate geometries and target dates, our distributed clusters execute mathematical calculations and return structured JSON telemetry metadata or binary georaster matrices.
Satellite Imagery API
Retrieve Sentinel-1, Sentinel-2, Landsat, and MODIS metadata, bands, and cloud-free composited GeoTIFF rasters.
Environmental Indices API
Calculate vegetation health (NDVI, EVI), burn severity (NBR2), soil moisture (SAVI), and water indicators (NDWI) on demand.
Terrain Services API
Query Digital Elevation Models (DEM), calculate local slopes, flow aspects, and exact topography elevations.
Bearer Token Authorization
To authenticate, obtain a key from the early access portal and pass it as an Authorization header. All API endpoints enforce SSL encryption and require active credentials.
