Hi Frank I wonder if you could help me with the following points which relate to DEM on a gps. 1) One of the problems of DEM on a gps is the intensity of darkness which you get near steep hills. It looks terrific in Basecamp but I prefer it to be lighter. I have experimented with higher values of dlon , i e dlon=.01 - this does seem to decrease the contrast but instead ofcourse it tends to spread a grey veil over the whole map. Is there another option I could use ? 2) Related to this ; its great to be able to create different zoom levels , however I have not been able to do the following: level 1 - no dem level 2 dem This would result in a more Basecamp style zoom, where the dem disappears when you zoom in. I tried --dlon=0 --dlon=0.0027 etc but setting it to 0 causes an error Would this be at all possible? Thanks in advance r Nick On 02/11/2017 21:27, lig fietser wrote:
I'm afraid I don't understand your tools Frank.
I guess I will wait until mkgmap has included the DEM handling.

i don't now your build-process. But i have installed your original map (without the DEM's). After you include the DEM's in this IMG files, create with gmtool with this NEW IMG's a new TDB.
For the old TDB you get with
gmtool -i 10010000.tdb -I 2
the following output:

The main-part is a long list of all mapnumbers/files with the subfiles. It is necessary to rebuild this list with the DEM-files with their filesize. That's why use the NEW IMG's for this.
