Hello,
I have 2334 raster grids (Geodatabase raster dataset, 1 band, 16 bit signed integer) that I want to sum into one raster. These rasters all have different spatial extent. Due to the large number of grids, using Raster Calculator is not really an option.
I have tried using the Cell Statistics tool to combine these grids. I unchecked the "Ignore NoData in calculations", set the processing extent to "Union of inputs", however it doesn't seem to work. I only get the sum where grids overlap.
I have read in the forum that one can get around this problem by replacing NoData with zeros, ie by using Con( IsNull[gridname], 0, [gridname] ) in Raster Calculator. However, this will once again be a bit boring when having thousands of grids.
Is there any solution to this problem?
Best regards,
Magnus
