I have a weighted overlay that identifies the most important areas in a corridor scaled from 0 - 100. I would like to be able to click on a cell and be able to identify which input rasters contributed to the weighted overlay.
I think I should convert all inputs into weighted overlay to a value of 1, do a combine and then combine with the weighted overlay?
Any ideas?
I used Combine in my related question Cell statistics sum resulting cells to indicate original input rasters

to insert a link. If some of your rasters have no data areas and you want to figure out which ones do or don't factor into the overlay, then your first part works (input factors to binary, Combine them). But you can only get what you want from that raster. If you then Combine that with the overlay result you're likely to have a tremendous number of unique values which will kind of make it useless. You may be looking at a raster attribute table or multiple bands.
