I have a polygon in a specific shape and I want to remove this area from a raster. Specifically, I have a polygon outlining prairie soil in Illinois, and I want to remove this area from the USA soils crop production raster. When I use the clip raster function, it clips out in a rectangle the area around the prairie polygon.
I need to either make the prairie values zero or remove them from the raster.
Please help!
