Should it matter whether rasters are 'signed' or 'unsigned'? ... View more

Let's first focus on figuring out why Weighted Overlay crashes Arc when I run the stand alone tool. This happens when I add more than 5 of the input layers in the ATV.gdb below. All input rasters are 8bit integer, most unsigned, and all snapped to the same extent and same 30m cell size: All input rasters have integer values from 0-3. Some grids have NoData values and not 0 values. Should this matter, as long as I scale those NoData values to 0 in the tool? ... View more

I am having the same issue with the stand alone tool as well as model builder. I want to combine 13 eight bit integer rasters into a weighted overlay. The tool seems to crash at 5 input layers now. I say now because a couple months ago I was able to run the tool with these layers in model builder. The tool also crashed ArcGIS when trying to process 6 input rasters in the stand alone tool. My machine has 16GB of memory and a 64bit processor. I have no spaces in my file names and have even reduced the length of file pathways substantially. I don't see running multiple pieces separately as a viable option to the analysis because the layers are dependent on each other, summing to the total of the whole model. Does anyone know if this is a known bug or is there a solution? Thanks. ... View more
