ogr2ogr -simplify <tolerance> Distance tolerance for simplification. Note: the algorithm used preserves topology per feature, in particular for polygon geometries, but not for a whole layer.
Markus, Thanks for confirming this approach.
... keep in mind that AFAIK this may damage the topology (i.e. gaps and slivers may arise between polygons). So, select the <tolerance> with care...
Given that I have no experience selecting tolerances for simplfy please suggest what I should read to make an informed first guess. Regards, Rich _______________________________________________ grass-user mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/grass-user
