I want to make elevation difference map by differencing of two Dem so that I may graphically frepresent elevation changes over different parts of my study area which is glacier.
One workflow is to use the MINUS geoprocessing tool from the Spatial Analyst extension. Basically, it's subtracts the cell value in the 2nd raster from the cell value in the 1st raster and writes a new raster with the cell differences.
