[GRASS-user] Creating 3D Vector file (v.in.ascii) for eventual use in NVIZ

[Jachym Cepicky]

hallo,

i made  some presentations about how to create 3D vectors quick&dirty
way.

see
http://fossgis.de/wiki/index.php/GRASS-GIS_-_Vektoren_in_der_dritten_Dimension
(german)

or presentation to 3D beginners workshop on foss4g2006

see also v.extrude && v.drape modules, how they are made
