I didn't find an answer in the archives so. I have a shapefile of polygons and some of the polygons are duplicated. I thought I could use v.clean tool=rmdupl to get rid of these polygons. I use v.in.ogr to read it in and I get the following: WARNING: 8 areas represent more (overlapping) features, because polygons overlap in input layer(s). Such areas are linked to more than 1 row in attribute table. The number of features for those areas is stored as category in layer 2 That is correct in that there are 8 duplicate polygons but the only different attribute is the cat which grass added? What am I missing? I then tried v.clean tool=bpol,rmdupl and nothing changes it still has the 8 duplicates. What am I doing wrong? I am using grass 6.3.0 on fedora core 14 linux. Thanks. |
