Detailed Description

Derives shaded relief raster maps (geo-coded hill shading) of DEM grids.

Hill shading is a method to visualize a surface grid model by illuminating it using a light source shining from a certain direction. Artificial shadows are calculated depending on the slope (steepness) and exposition of the surface w.r.t the direction of the light source. Depending on the artificial shadow length, grey values (0=shaded..255=exposed) are assigned to each cell of the output raster.
