[mkgmap-dev] wrong elevationprofiles

Hi Minko

Talking about DEM elevations, the hiking map of http://openmaps.eu is a free
DEM map made with cgpsmapper, so maybe the DEM code is known outside Garmin? 
_______________________________________________

have checked one of the imgs containing DEM from the site you quoted -
although cgpsmapper was perhaps  used to create the imgs in the tdb file he
mentions the 'legitimate' use of Garmins' MPC - see
http://developer.garmin.com/web-device/mapsource-product-creator

I have a feeling that although Stan has tried to decode the DEM structure,
his cgpsmapper is still not offering DEM. Would be great if it did !

The set-profile=1 only works if contour lines are included - in fact I've
noticed mkgmap automatically sets it to '0' in the tdbfile if no contours
are found.
