I need to know, how much each of my calculated catchments is overlapped by the others, to assess the supply of the commodity per source point.
I calculated supply catchments for a total of 110 point features derived from an accessibility analysis for a specific commodity. That makes 110 catchment rasters with 3 classes OR 330 feature classes if converted to polygon by using the 3 classes.
I know the methodology to do it with intersect, but with this amount of layers it just takes too much time.
Any idea how to do it?
