[GRASS-user] Adjacent polygons rejected by v.patch

Tue Nov 18 12:49:45 PST 2014

Hi,

I'm trying to join polygons, but unfortunately some, at the boundaries
are been rejected by v.patch. The Screenshot attached is showing this.

1) Import shapefile with v.in.ogr:
   v.in.ogr dsn=ma.shp output=maGrass snap=0.001 min_area=0.0001
   The same for others shapefiles pi, ce, rn, pb, pe, al, se and ba

2) Aggregate polygons with v.patch
   v.patch
input=maGrass,piGrass,ceGrass,rnGrass,pbGrass,peGrass,alGrass,seGrass,baGrass output=nePatched

I do not figure out how I can solve this issue.

Any help are welcome.

Humberto
