Now that we go 3D...
Loading a 3D polygon layer, for example this GDB:
The provider (ogrinfo reports the geometries as:
3D Multi Polygon
While QGIS in it's Layer Properties/Information panel shows them as:
Geometry Polygon (MultiPolygon25D)
See screen shot..
From Martin I understand there are 'different' types of 3D:
But at least QGIS should show I think the right result?

This is just a terminology difference. 25D = 2.5D. Probably that the "3D MultiPolygon" in ogrinfo is not appropriate, since a multipolygon is supposed to be a planar thing, so at best 2.5D. Perhaps MultiPolygonZ would be a more neutal terminology. The only real 3D geometry is a PolyhedralSurface (not sure if that's handled by QGIS yet)

Feel free to close this.
My point is just that I think 'notable geofoss tools' should use the same (and preferably professionally right) names and definitions for everything.
And I'm aware that this is more difficult with a widespread/anarchitic bunch of coders (compared to a dictotarial multinational), but I think we at least should try :-)
@even: is it worth starting a discussion about this (both on GDAL an QGIS lists?) so we can hopefully come to a shared (documented) definition?
Else: just close it.
