[mkgmap-dev] [PATCH] Enable elevation profile in MapSource

Sun Feb 14 22:53:31 GMT 2010

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
