Thank you for the suggestion, digging deeper I've found also http://lists.osgeo.org/pipermail/grass-user/2011-January/059175.html Now trying this option. Meanwhile, would it be useful setting up a wiki page on "Large vector data processing" similarly to what is in place for raster files? Or is there already and I overlook it? @Alexander Muriy : thanks for the suggestion. I ask you to please contribute a section as soon as I create the page ;-) Thanks -- Best regards, Dr. Margherita DI LEO Scientific / technical project officer European Commission - DG JRC Institute for Environment and Sustainability (IES) Via Fermi, 2749 I-21027 Ispra (VA) - Italy - TP 261 Tel. +39 0332 78 3600 [email protected] Disclaimer: The views expressed are purely those of the writer and may not in any circumstance be regarded as stating an official position of the European Commission.
