[GRASS-user] v.surf.idw

Dear list,
I got the following message when v.surf.idw used with DGM vector points :

v.surf.idw:

15984 data sets selected from table.

0 points loaded.

v.surf.idw: no data points found.

Input-Layer: Shape (Point)
count of interpolation points:default (12)
column: elevation points

First, I did the v.db.connect command to link with the dbf attribute table.

Do you have any suggestions?

Regards

Chris

are all the points outside the current region?

Does "d.vect points_map" show them?

What if you run "g.region vect=points_map" first? (then "g.region -p"
and check the resolution and rows/cols aren't more than ~ 5000x5000)
