I need to create an Hillshade from a DEM. The DEM has a projected CRS and I have performed Calculate Statistics before running the Hillshade tool. I am using ArcGIS 10.3 and I have Spatial Analyst enabled.
When I run Hillshade from the toolbox, the raster that is created has not values ranging from 0 to 254, but has values ranging from 124 to 220.
What causes this "strange" beahaviour of the hillshade function? Is there a way to produce an hillshade raster with proper values?
EDIT: if I activate "Use Hillshade effect" on the DEM, I get a series of squares that are really not good looking (like in this post Understanding garbage hillshade output from ArcGIS for Desktop?)
the derived hillshade seems ok instead, it doesn't show this problem
