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.

Ronny
