<div><br>Hamish suggested using 'v.in.ogr -c ' (does not clean polygons) which didn't worked for me. <br>I partially solved using v.in.ogr without min_area and snap parameters but when patching adjacent shapes I do not some polygons lost area.
<br>Are you experiencing something similar with ArcGIS shapes?<br><br>regards<br>raffaele<br></div></div>
