that's not an error, just a warning. there are different ways to get the point coordinates: e.g. v.report map=mysampleoutlet_snapped@user1 option=coor cat|x|y|z 1|635555|219665|0 or v.db.addtable - Creates and connects a new attribute table to a given layer of an existing vector map. v.to.db - Populates attribute values from vector features. v.to.db option=coor: point coordinates, X,Y or X,Y,Z and some others .... ----- best regards Helmut -- View this message in context: http://osgeo-org.1560.x6.nabble.com/snap-pour-point-for-r-water-outlet-tp5314835p5314937.html Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
