SAR Terrain Geocoding
Provided by 
Raw radar is not a map. It is recorded in the geometry of the satellite’s own line of sight, distorted by terrain, uncalibrated and speckled. Everything a user actually wants from SAR (e.g.: flood extent, ground motion, vessel positions, change) starts by undoing that. This service does exactly that and nothing more, and it does it the same way every time.
The chain applies precise orbit files, removes thermal noise and border artefacts, calibrates to a physical backscatter coefficient, then performs Range-Doppler terrain correction against specific DEM so each pixel lands where it belongs on the ground. Optional speckle filtering and decibel conversion round it off, and the result is written as a cloud-optimised GeoTIFF clipped to the area of interest.
