[GRASS-user] How to remove small vectors in a shapefile in GRASS 6.4.1

Hello,

I want to remove small vector in a shp. I tried with v.generalize but I only
managed to remove segment of a line.

The image shows in black the vectors I want to "clean". And in green is the
result I obtained with v.generalize.

Has someone an idea?

Thanks

Lucien

Try v.clean tool=rmarea threshold=XXX
That will remove all areas smaller than XXX.
