Hello,
_Environment_
Ubuntu: 12.04.03
UbuntuGIS Repository: Unstable
qgis: 2.0.1-Dufour
saga: 2.0.8
GDAL/OGR: 1.10.0
Grass: 6.4.3
I've been working with QGIS, looking at its potential as a GeoProcessing environment.
I'm particularly impressed with its Processing environment, especially with its integration with Grass and SAGA.
I have a query that may or may not be related to how QGIS is packaged.
I'm trying to do some quite involved 'automated' vector data processing via Grass algorithms that really require a topological data set.
Unfortunately I don't really seem to have an option in the environment that I'm using. The dialogs via QGIS that launch Grass algorithms typically default to a shape file format. They do allow options, however these are typically of similar style to a shape file and do not appear to be topological in structure.
Is there any way to work with a topological data format in this environment?
Is this constrained by the options compiled with OGR?
Bruce
