Coordinates disappear when exporting SAR data

[ABraun]

SNAP interprets the geocoding information of the SAR metadata. But in most cases the data itself is not projected yet.
You need at least to apply a map projection first before exporting the SAR data.

Which data are you using? Which product level? SAR data often comes in SLC / L1 level which is not projected yet. Please also see here:

GTC (Geocoded terrain corrected) data

it means that its already ground-range corrected. Unlike SLC data the pixels’ areas are already of same size. Astrium has made nice graphics for this case. They refer to TerraSAR-X but the principle is the same for most SAR satellites: Slant Range Complex (SLC/SSC/L.1.1) [image] Data is neither multi-looked nor projected Ground Range Detected (GRD/MGD/L1.5) [image] Data is multi-looked but not projected Geocoded Ellipsoid Corrected (GEC/L2.0) [image] Data is projected but topographic d…
