[gdal-dev] 3D maps

[Malm Paul]

Hi!
I have a geometry set of triangles (e.g land area), including
elevations.
To be able to view e.g roads ontop those triangles I must insert points 
in the road polylines with the correct elevation in each intersection 
(roadline - triangle border). Att the same time I would like to insert 
the correct elevation of the original points of the road-polyline. is 
there a command that could do this for me?

 Kind regards,

 Paul
