Hi,
I’m trying to perform a SAR-Simulation
to extract the shadow and layover from a SAR image that was just before that calibrated, speckle-filtered, and terrain-correction (in this order).
Below is the error I get when I run the graph with gpt
:
INFO: org.esa.snap.core.gpf.operators.tooladapter.ToolAdapterIO: Initializing external tool adapters
Executing processing graph
INFO: org.hsqldb.persist.Logger: dataFileCache open start

Is it impossible to have the SAR-Simulation
operator performed after the Terrain-Correction
one?
Does it (SAR-Simulation
) have to be followed by a SARSim-Terrain-Correction
and Cross-Correlation
instead, as mentioned here)?
Thanks.
