Hi Markus, Thanks for answering. I solved using:
ogr2ogr -s_srs EPSG:23032 -t_srs EPSG:32632 repr_suolo_paes.shp suolo_paes_ext.shp and imported the reprojected map with v.in.ogr. All polygons are reprojected now. But I noticed that using v.proj the map was reprojected with an important error .I have another map of the same area, when I try to overlay them they are in two different places, very far apart. But when I overlay the map reprojected with ogr, everythings looks OK. Couldn't it be a bug of v.proj? Has anyone had a similar problem using v.proj?
