Hi Markus,<br><br>Thanks for answering. I solved using:<br><br>ogr2ogr -s_srs EPSG:23032 -t_srs EPSG:32632 repr_suolo_paes.shp suolo_paes_ext.shp<br><br>and imported the reprojected map with v.in.ogr. All polygons are reprojected now. <br>
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.<br>
Couldn't it be a bug of v.proj? Has anyone had a similar problem using v.proj?<br><br>Thank you<br><br>Margherita<br><br><br><div class="gmail_quote">2010/12/5 Markus Neteler <span dir="ltr"><<a href="mailto:neteler@osgeo.org">neteler@osgeo.org</a>></span><br>

You are reprojecting from UTM_32_ED50 into ...?<br>

<br>
</div>In any case, you may need to clean up the topology *before* running v.proj.<br>
Perhaps the original map isn't clean.<br>
