The TopologyException error comes from the GEOS library. You might need to upgrade your GEOS to a newer version and see if it helps. I've downloaded the http://thematicmapping.org/downloads/TM_WORLD_BORDERS-0.3.zip dataset and tried -wrapdateline on it. It works great. Except that it is not needed at all since the longitudes of the dataset are between -180 and 180, so there's nothing to wrap at all... > > Take care, > Sina > > > Website: www.SinaBahram.com > Twitter: @SinaBahram > > > -----Original Message----- > From: Eli Adam [mailto:[email protected]] > Sent: Monday, August 06, 2012 9:19 PM > To: Sina Bahram > Subject: Re: [gdal-dev] Topology Exceptions on Non-Noded Intersections > > This is about Google Earth not Google Maps, but there may be something > relevant here, http://blog.opengeo.org/2010/08/10/shape-of-a-polygon/ > > Eli > > On Mon, Aug 6, 2012 at 5:50 PM, Sina Bahram <[email protected]> wrote: > > Hello, > > > > I receive the following errors with the -wrapdateline argument. > > > > ERROR 1: TopologyException: found non-noded intersection between > > LINESTRING (-59.7742 -72.9003, -59.8494 -73.2331) and LINESTRING > > (0 > > > -73.1221, -89.3211 -73.0542) at -59.8141 -73.0766 > > ERROR 1: TopologyException: found non-noded intersection between > > LINESTRING (-59.7742 -72.9003, -59.8494 -73.2331) and LINESTRING (180 > > -73.2589, -89.3211 -73.0542) at -59.8141 -73.0766 > > > > More details can be found on this question I asked: > > http://gis.stackexchange.com/questions/30922/how-do-i-split-polygons-that > > -cross-the-dateline > > > > any advice? > > > > Thanks > > > > Take care, > > Sina > > > > Website: www.SinaBahram.com > > Twitter: @SinaBahram > > > > > > _______________________________________________ > > gdal-dev mailing list > > [email protected] > > http://lists.osgeo.org/mailman/listinfo/gdal-dev > > _______________________________________________ > gdal-dev mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/gdal-dev _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
