Descartes Maps

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.

How we pre-process the imagery

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

Why multiple bands matter

Landsat 8
RGB bands

15 meters per pixel resolution

3.1 trillion pixels per band (Red, Green, Blue)

Built from 70 trillion pixels per band captured from 2013 to 2017 (320 TB)

Red Edge bands

20 meters per pixel resolution

1.8 trillion pixels per band (RE1, RE2, RE3)

Built from 22 trillion pixels per band captured from 2015 to 2016 (120 TB)


20 meters per pixel resolution

680 billion pixels

Built from synthetic aperture radar (SAR) range/azimuth measurements captured from 2014 to 2017 (86 TB)
