Hi all, I'm trying to join a large set of "vectorial tiles" that i have, into a unique vectorial map. What i'm doing is something like this, for each "tile" (in the example is called filaN):
v.overlay ainput=sumaFilas atype=area alayer=1 binput=fila6 btype=area blayer=1 output=sumaFilas2 operator=or olayer=1,0,0 v.db.addcol map=sumaFilas2 layer=1 'columns=union INTEGER' v.db.update map=sumaFilas2 layer=1 column=union value=1 v.dissolve input=sumaFilas2 output=sumaFilas2 layer=1 column=union --overwrite g.remove vect=sumaFilas g.rename vect=sumaFilas2,sumaFilas At first, the v.overlay is instant, but when processing the map number 100, it can be several hours. Anyone knows an alternate way to do this? The first solution I adopted was making this by rows of 100 "tiles", and then joining the rows (what i'm doing in the example above). It worked for me since i only has todo a "small" map (1 week of processing), but now i need to do one MUCH more big. Thanx in advance if anyone knows something.. or not :) Andres -- View this message in context: http://n2.nabble.com/V-overlay-very-slow-tp4169783p4169783.html Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
