I have a set of DEMs that have different extents due to different data being available at each of the sample points these DEMs were generated from. I need to use these to create a set of uniformly sized rasters with the same spatial extents. This would mean creating a new raster that has a null or 0 value everywhere except when it can use a value from the original (which is smaller). I've played with con
but it doesn't seem to do what I want.
Another way I've tried to approach this is to create the larger raster at the resolution I want, then use the raster calculator to go through and set values when it can extract them from the smaller original raster, leaving them blank/0/null otherwise. But I haven't been able to figure out how to implement that because I don't know how to refer to whether you're outside the extent of a raster or not. Please let me know if I need to reword part of this to be more clear.
