[gdal-dev] Polygon simplification using the borders to preserve topology

[Roger Veciana i Rovira]

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
