[mkgmap-dev] DEM and SRTM hgt files: size too small

Thu Nov 1 10:03:33 GMT 2018

Hi Thorsten,
viewfinderpanoramas provides files for that area too. Download cells M32 
and M33 from
http://www.viewfinderpanoramas.org/Coverage map viewfinderpanoramas_org3.htm
The unzipped files all have a size of 2818 kb, and work well with mkgmap.
Kind regards,
Bernhard
