Moritz, could it be a QGIS problem? I assume you have set up the projection in GGIS to 31370. What happens if you open your GRASS mapset in QGIS and load the GPS data as a GRASS vector (with on-the-fly)? _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
