Classify DEM/LIA in SNAP

Microwave Toolbox
#1

In SNAP, is there any tool to perform a binary classification on either DEM or Local Incidence Angle (LIA) in terms of ROIs defined for water?

Thanks

You could nest conditions in band maths like a decision tree.

In band maths? Would you please explain a little more?

you can define thresholds and assign values according to conditions.

For example (in words):
IF dem > 450 AND incident_angle < 45 assign 1, else 0
