What is Hillshade map?

Shaded relief, or hillshading, is a technique where a lighting effect is added to a map based on elevation variations within the landscape. It provides a clearer picture of the topography by mimicing the sun’s effects (illumination, shading and shadows) on hills and canyons.

What are the two parameters needed to create the Hillshade?

Azimuth and altitude



The properties altitude and azimuth together indicate the sun’s relative position that will be used for creating any 3D model (hillshade or shaded relief). Altitude is the sun’s angle of elevation above the horizon and ranges from 0 to 90 degrees.

What is the difference between Hillshade and DEM?

The hillshade layer doesn’t show elevation, but rather uses the elevation data from the DEM and an assumed position of the sun to infer which areas will be shaded under some given circumstances. Unless you are concerned with the illumination of your fault lines by the sun, it is unlikely this will be useful to you.
 

What is the method of hill shading?
