i know its allmost the same question as "Use Raster Calculator to Modify DEM Elevations based on Vector Layer.but i am trying to build a model but i am stuck.
my first model, and i got that to work has this expression:
Con(IsNull("%Output_raster%"),float(%Double%), "%Output_raster%"). but this sets a value.
what I now want is to subtract a value from the DEM using this model.
can sameone help me with the right expressing.
Thank you and Greeting Peter
