I'm using ArcGIS 10.2. I need to convert two rasters from 8bit unsigned to an 8bit signed raster so I can do a subtraction and get both positive and negative values.
I've tried to use the copy raster tool that allows you to set the raster pixel type, but it always comes out the other side as an unsigned raster.
I tried converting my GRID to a .tiff, then using the copy command, but the Copy Raster tool will only output a GRID. After converting and copying I still got an unsigned raster output.
