hi ,
i've a large point vector file (ascii 160 mb)
i've loaded it into grass using v.in.ascii : cat file.xyz | v.in.ascii -r out=rst_k fs=" " col="x double, y double, z double"
then i added a column to the vector table using : v.db.addcol map=rst_k layer=1 'columns=kval integer'
v.info:
Type of Map: Vector (level: 2)
Number of points: 1460445
Map is 3D: 0
Number of dblinks: 1
Projection: Transverse Mercator (zone 0) |
| N: 4507802.498 S: 4494627.516 |
| E: 2531867.500 W: 2523932.502
r.info :

| E: 2531867.5 W: 2523932.5 Res: 5
| Range of data: min = 1 max = 6
my targhet is to add the raster value to the kval column of my vector points,
to do so i'm tring to use :
v.what.rast vector=rst_k raster=k6 layer=1 column=kval
i'm tring it on this region :
g.region:
projection: 99 (Transverse Mercator)
zone: 0
datum: rome40
ellipsoid: international
north: 4507802.498
south: 4494627.498
west: 2523932.502
east: 2531867.502
nsres: 5
ewres: 5
rows: 2635
cols: 1587
cells: 4181745
...after 24 hours at 100% cpu ... nothing is done ,
i force to kill the process 
but if i try it on a smoll area it works fine.
have you any suggestion about?
can i divide my area in many subregion
and then patch the results ?
thanks
Massimo
