Hi!
Does anyone has created an elevation map like it is described in [1]?
Maybe you would like to share your style and typ-files?

I saw that, and thought that it looked like a hell of a lot of work! If you’ve got the energy to do that, perhaps you have the energy to reverse engineer Garmin’s DEM format? 
I’m afraid its not as simple as swapping typ and style files.
As contour lines are lines not polygons, you need to turn them into polygons - gpsmapedit could be used but its still hard work.
Some contours may almost make a polygon,in which case you could convert the IMG into an .mp file and change the line into a polygon etc.
However, because of their length, most contours are split into smaller line segments and need to be joined first .
You could experiment replacing [POLYLINE] with [POLYGON] and possibly giving type numbers an extended property, ie 0x121 etc.
Give each polygon in your typ file a different mesh and the effect can be ‘quite interesting’.
