I wonder if it is possible to load German NAS-Data into QGis or to convert them to Shapefiles. I'm using QGIS 1.8 on Ubuntu 12.04.
I'm sorry, I thought I did - NAS is the new Geodata-format, based on ALKIS-Data: http://de.wikipedia.org/wiki/Normbasierte_Austauschschnittstelle
I installed the current Master on my Ubuntu 12.04 machine today and typed "ogr2org --formats" but NAS didn't appear on the list.
If I check my ogr-version it says 1.7.3 - as I understood NAS is supported from 1.8.0 onwards.
Did you do anything special to install that version?
