Description
Very useful hillshading that can enhance topographic detail. This method is implemented, for example, in the SAGA GIS (src\modules_terrain_analysis\terrain_analysis\ta_lighting\HillShade.cpp).
This could be an additional option (e.g. -combined) to gdaldem hillshade utility.

Looks nice. Updating apps/gdal_utilities.dox with the documentation for the new option would also be appropriate. I'm wondering how one can explains the effect of -combine with words in English... Is there some reference in the scientific litterature about this algorithm that could be refered to ?

Was any references for this provided? I don't see anything here http://www.gdal.org/gdaldem.html#gdaldem_hillshade and google isn't super helpful.
