[mkgmap-dev] Elevation data just partially accessable by Basecamp

Hi Gerd,

for GMapTool to set first flag, all tiles should include DEM.

I'm afraid, that mapset with mixed tiles - with and without DEM - is not 
standard for Garmin. It might be impossible to invent a proper way to 
handle that configuration.

Some years ago I did a number of tests and chose the most safe way to 
set both flags. I remeber, that some arrangement of tiles and flags can 
cause errors for Mapsource, but I'm not able to directly give examples. 
Unfortunately I don't remember now, what was the reason for GMapTool 
algorithm.
