I’m trying to compare vales of two rasters, however the rasters extent are not the same (but one raster is not smaller than the other, the extent differ in different places - see picture attached). I’m struggling to do this with the raster calculator as when I minus one from the other I do not get a difference form the full extent as some of the values has been set to NoData, so only get the difference where they overlap. Is there any way I can compare these rasters not only where they overlap but where they don't?Screenshot of the rasters I'm trying to compare
