Hello, I have the a shapefile full of polygons, and* *I want to simplify them, preserving the points they share. ogr2ogr -simplify simplifies each polygon independently, so the borders don't fit properly. Is there a way to do this with GDAL? TopoJSON format( https://github.com/mbostock/topojson), for instance, uses the shared segments instead of the polygons, and simplifies them well, but I prefer to use GDAL.
Thank you Roger
