How to extract a bigger raster with a smaller raster in the way that the bigger raster has NoData where the smaller raster cells are?
I want to extract the raster cells from a big raster with the raster cells from a smaller raster which is overlapping with the bigger raster. Unfortunately, I cannot find a tool for that in ArcMap 10.3.1, but is there a way to do it? I do not want to subtract the values, but there should be noData in the new bigger raster where the bigger raster is overlapping with the smaller raster, like a hole in the bigger raster with the extent of the smaller one.
I tried this:
Con(IsNull("smaller"),"bigger","bigger" == "smaller")
But I really need to put the values from the smaller raster extension into noData in the new raster.
