I've calculated relative heights in ArcGIS, now I'd like to calculate relative heights (range between maximum and minimum cell value in window 3x3) in SAGA. It's important that I don't want standardized values (0-1).
There is a module called "Relative Heights and Slope Positions", it creates few outputs, but they don't correspond directly to results calculated in ArcGIS (Focal Statistics)
These are sample results from ArcGIS:
Does anyone know how to convert the results from SAGA into values like I've calculated in ArcGIS with mentioned module or other SAGA module?
