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.
... 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...
