PROBLEM
When running the weighted overlay tool, the output raster is a blank image with values from -2,147,483,648 to 2,147,483,648.
All of the images that are specified within the tool are not overlaying each other. For example, if rasterA overlaps rasterB, and rasterB overlaps rasterC, but rasterA does not overlap rasterC, an empty raster will be created.
1. Open ArcToolbox
2. Spatial Analyst Tools > Reclass > Reclassify
3. Specify the input raster
4. Specify the 'Reclass field' as Value
5. Under 'Reclassification', change NoDATA under 'New Value' to 0.
6. Specify an Output Raster and hit OK.
