[Qgis-user] Using/visualizing 3D data (Z values)

[gene]

Waiting for Globe, a solution to extract the z values of 3D shapefiles is to
use ogr or shapely (see in qgis-developer

). 

After  you can use matplotlib or other Python modules like  * Visvis
<http://code.google.com/p/visvis/>  * to visualize the data in 3D:

(see also, with  http://code.google.com/p/visvis/wiki/Screenshots

This solution also applies to layers with z attribute.

The full explanation of the processing is given, in French, at  QGIS,
représentation 3D des couches vectorielles (shapefiles dits 3D ou shapefiles
avec attributs z) avec avec les modules Python Matplotlib ou Visvis à partir
de la console Python
