Dear users,
this is my problem: i have a shape file with 166K points and a shape file
with 1 area (with some holes).
I want to delete the points liyng into the area. The two file have the same
CRS.
Vector->Spatial Query->Select source feature from ..points...where the
featureĀ  intersects reference feature of ....area
No results QGis not responding, no way to give up...just stop QGis (2.6.0
on W7-64bit)
The same operation in Geomedia takes no more than 5 seconds and the results
is more or less 32k points.
Any suggestion?
Thanks
