I have made the slope map of a particular region using the dtm. How can I produce a slope variation map, which shows the difference in slopes between adjacent cells? Thanks in advance.
You would have to 'shift' the slope map in the 8 cardinal directions by 1 cell (dx, dy) and subtract each from the original, if you want to find the difference in all of the 8 major directions
Shift—Data Management toolbox | Documentation
of if you want the rate-of-change of the slope, you can look at
Curvature—Help | Documentation
Let us know if it works as you needed.
