Re: [GRASS-user] GRASS-way to delete points from a map and attribute table

[Micha Silver]

IMHO it would be helpful to add a flag to v.edit to also delete the database entries when tool=delete. In general use, when I delete a feature, I don't expect to leave orphaned entries in the attribute table.

I already tried v.edit but here the points are not deleted from the attribute table. I could also use v.extract with the reverse flag, however this requires to define a new output map (which I would like to avoid if possible). Any straight forward way in GRASS?   /Johannes   _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user -- Micha Silver Ben Gurion Univ.
