Hi GRASS list, I've imported a shapefile of country polygons and am trying to use v.clean properly to clean the topology. Here is what I have done so far:
456 v.in.ogr dsn=unep_coastlines.shp -o type=boundary out=unep_countries 461 v.clean unep_countries out=unep_clean type=boundary tool=rmdangle,rmsa,break,rmdupl,rmbridge,bpol thresh=-1,0,0,0,0,0 467 v.centroids unep_clean out=unep_clean_2 475 v.clean unep_clean_2 out=unep_clean_2_rmdac tool=rmdac thresh=0 After doing this, I see that I still have some strange looking borders in Asia. You can see what they look like here - http://lagerratrobe.blogspot.com/2009/10/using-grass-to-fix-topology.html. I'm not 100% sure what the "x" means, but I think it indicates that the country border is not a solid line. How can I remove those extra bits, and create proper areas for each country? Thanks, Roger -- _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
