[GRASS-user] r.contour failing?
Hi all. I cannot get r.contour working. It always takes a lot of CPU, then crashes. Anyone has more joy? grass 7.0.1-2 from Debian sid.

[GRASS-user] river and dams in netwok analysis
Dear all, I'm try to understand network analysis fonction in grass 6.4. I have 2 layers : * Points layer with the spatial dams repartition * polylines layer with rivers I would like to know for each dam how is before and how is after in the network. I at the end I would like to export a shp files with those data in the attribute table. I have find some informations here : http://www.ing.unitn.it/~grass/docs/tutorial_641_en/htdocs/esercitazione/network_analysis/node1.html And I have done that : ##save a region v.in.region --overwrite --verbose output=region_central ## clip rivers v.overlay --overwrite --verbose ainput=troncon_dordogne@PERMANENT atype=line binput=region_central output=rivers_central operator=and v.overlay --overwrite --verbose ainput=troncon_dordogne@PERMANENT atype=line binput=bv_dordogne@PERMANENT output=rivers_bv operator=and v.select ainput=barrage_energie@PERMANENT binput=bv_dordogne@PERMANENT output=barrage_e_bv ##Connect dam points to the network ## thresh=500 means that only points within ## the distance of 500 metres are connected to the lines v.net --overwrite --verbose input=rivers_bv points=barrage_e_bv@PERMANENT output=network operation=connect thresh=500 ## link the attribute table of the fire stations to layer 2 of the network map v.db.connect -o --verbose map=network table=barrage_e_bv@PERMANENT layer=2 But I'm not so smart with data manipulation in GRASS so If someone can give me a hand it's nice :-) Thank you Best regards E. -- Cordialement Etienne DELAY Chaire: Capital environnemental et gestion durable des cours d'eau laboratoire GEOLAB UMR 6042 CNRS Université de Limoges, FLSH 39E rue Camille Guérin 87036 Limoges blog : http://elcep.legtux.org ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
