Descartes Labs is excited to release three distinctive global composites. We built them using our platform, a cloud-based parallel computing infrastructure that accesses our unique corpus of pre-processed satellite data using our lightning-fast APIs. Explore the composites in your browser now!
Each satellite provides unique image resolutions and frequency bands. For starters, we created composite maps from Landsat 8, Sentinel-1, and Sentinel-2 imagery.
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)
Sentinel-2
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)
Sentinel-1
SAR
20 meters per pixel resolution
680 billion pixels
Built from synthetic aperture radar (SAR) range/azimuth measurements captured from 2014 to 2017 (86 TB)
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
We’re excited about what’s in store for Descartes Maps, and we hope you are too. If you have any questions about our composites, please send us a note.
