I'd like to combine about a dozen rasters into one raster that contains the "summed" cell values where overlaps occur. In doing so, I need to be able to retain cells that either have no data, or that do not overlap with any other rasters.
FYI, Cell values are stored in an integer field in each raster.
I have tried the Raster Calculator, however it doesn't seem to do well with the "No Data" cells- it only creates summed cells where rasters overlap.
I have also tried the "Cell Statistics" tool, however the output feature it generates doesn't have any data.
