Hi, As expected, GRASS 7 out-performs all the others. Nowdays, when working with large datasets, I rather use PostGIS. Fast, robust. With GRASS 7 you can easily talk to your postgres databases which is a great help.
You could try GRASS from QGIS but as far as I know, qgis doens't peak to grass7. Cheers, António 2013/9/18 [email protected] <[email protected]> > Any suggestion on this?
