[mkgmap-dev] DEM contrast option?

Wed Jul 4 17:52:44 BST 2018

I just made my first map with the new DEM-option and I´m impressed. Pretty easy.
But I wonder why DEM shading looses contrast in higher resolutions in BaseCamp:

My Style has background poly 4a and 4b (both transparent), however they are not mentioned in polygons. I wouldn´t know how to tag them anyway.
And even with a completely blanked typ-file the difference is visible:

HGT´s are 3“ data from viewfinderpanaramas.org

To keep the contrasted DEM up to higher resolutions/zooms I played with all DEM-options from help, and also with transparencies, but that had no effect - the softer shading remains.

I see the switch in Basecamp somewhere between assumed resolutions 20 and 22.
How is this switch defined? Is there a value to adjust this?
