[GRASS-dev] v.external and 3D OGR datasources

[Benjamin Ducke]

Dear list,

v.external in GRASS 7 allows to link 3D OGR sources as a
new 3D GRASS map. In GRASS 6, only 2D links are made.
I tried changing the Vect_open_new() statement in 
GRASS 6's v.external to make a 3D link, but no success.

Is there any deeper reason, why 3D OGR links are not
possible in GRASS 6? I couldn't find a clue in the API,
and would be grateful for any info on how difficult
it might be to backport the 3D OGR access to GRASS 6.

Cheers,

Ben
