>I have what I think is a large shapefile. It is 122 MB (30 MB dbf file and 90 MB shp file).
not that large; a few weeks ago I've imported a ~1 GB shapefile; it took some time to import because of topological building, but it worked. >WARNING: Number of incorrect boundaries: 1586 >WARNING: Number of centroids outside area: 186 >WARNING: Number of duplicate centroids: 631 it seems there may be some issues e.g. overlapping polygons, self-intersections of boundaries, very small areas etc. try to use v.in.ogr instead in a location with the original projection and then reproject it. sometimes I get data sets with such warnings; first I open such data in QGIS; in master aka QGIS 3, there is a nice new topology checker to inspect about topological errors. after some cleaning in QGIS, I try to import the data by v.in.ogr without cleaning and afterwards clean the vector data by v.clean e.g. remove small areas, etc HTH ----- best regards Helmut -- Sent from: http://osgeo-org.1560.x6.nabble.com/Grass-Users-f3884509.html _______________________________________________ grass-user mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/grass-user
