[postgis-users] 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 in PostGIS that could do this for me?

Kind regards,    

Paul
