Reverse Clip (donut) With Raster Data

ParkGIS307

Hello all,

I have a DEM file I am working with. I want to take a polygon of a water body and remove those elevations from the elevation dataset. What I want to do would be similar to the erase tool but instead of vector data I am working with raster. The DEM file would look something similar to a donut after this. So far I have come up empty-handed as I try to figure this out.

Does anyone know how to do this or know of a work-around?

Thanks,

Please ensure you are using Clip function (not Clip Geoprocessing tool).

convert the polygon to a raster using the same extent, cell size and alignment etc.

You can use the Con tool in arctoolbox to remove the elevations in the water body

Con("Lake", "Elev", 0) # if you want to set the value to 0

SetNull("Lake", "Elev")

Where are you using the clip type options for inside or outside? This is the raster clip function but I do not see that option for outside/inside.
