v.transform - Performs an affine transformation (shift, scale and rotate) on vector map. https://grass.osgeo.org/grass74/manuals/v.transform.html not sure it is what you're looking for. ----- best regards Helmut -- Sent from: http://osgeo-org.1560.x6.nabble.com/Grass-Users-f3884509.html _______________________________________________ grass-user mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/grass-user
