Terrain Flattening - Error


I’m writing my graduation essay about terrain modelling and because of it use snap. I have to do radiometric terrain correction, for this i use a s1b-iw-slc. Found videos and documentation about it, but in the “Terrain Flattening” phase i get an error message.

Don’t know what doing wrong. Thanks in advance!


have you maybe saved the products as a TIF or another file format besides the suggested BEAM DIMAP during the orbit and calibration step? This causes loss of most metadata which are then no longer available to SNAP for subsequent processes.

The new update introduced two new parameters which don’t exist in your graph. I’ll fix this to put in a default in case old graphs are being used.
