Hi,

there seems to be a way to show elevation profiles for a route without having the DEM subfiles stored in the map.
There is a byte in TDB file's header section which can be set to 1. If set MapSource generates the profile from the contour lines. The result is not as good as having the full information from DEM subfiles but better than nothing.

Please try this patch, especially with maps without contour lines. Maybe setting this flag has to be bound to existing contour lines.

Is there any change to the .img themselves, or does this only affect the tdb???
(there is an option in gmaptool to enable fake profile, but it makes Mapsource crash sometimes when clicking on profile, was meant more for enabling maps to be seen in older basecamp versions).

I will try to see how it affects when you have contourline only maps / vs simply including them by tdb/overview map tomorrow. Too late for today...
