Descartes Labs has created three distinctive global composites - Landsat 8, Sentinel-1, and Sentinel-2 - using each satellites unique image resolutions and frequency bands. By using the Descartes Labs platform, we were able to pre-process all of the imagery to make an easy-to-access composite you can explore.

Co-register images for accurate alignment
Convert to standardized map projections
Remove clouds and correct for shadows
Adjust for camera angle and sun angle
Calibrate sensors against self and neighbors
Compensate for atmospheric degradations
