Hi Gerd,

I got a bit confused when I read  the doc/example

--dem-dists=number[,number]

If given, the option specifies the resolution(s) or zoom level for the DEM data. If not given, mkgmap tries to determine a reasonable value based on the resolution found in the *.hgt files. For PC programs like MapSource or Basecamp you only need one zoom level, for gps devies you need one for each resolution given with the --levels option. The actual values are given as distance between two DEM points. Higher disances mean lower resolution and thus fewer bytes in the map. Reasonable values for the highest resolution are somewhere between 1648 and 5520, 3312 is often used.

Example which should work with levels="0:24, 1:22, 2:20, 3:18, 4:16":

--dem-dists=3312,13248,26512,53024

This was found in a Garmin Demo map for transalpin data created 2009.

There are only 4 values for –dem-dist ,although there are 5 „Levels“.

This seems to be  in contrast to „…for gps devies you need one for each resolution given with the --levels Option ?

Regards

Andreas
