[gdal-dev] hillshading to vector

[Carlo A. Bertelli (Charta s.r.l.)]

Hello,
gdaldem makes a very good work and gdal_polygonize.py too, but the
combination is not so effective. Is there a way to obtain smooth polygons
representing shaded areas as it's possible with Arc? When using a dem, you
get polygons for pixels. Yes you can dissolve them, but you still have
jagged boundaries. I even tried to get contours from hillshading, but
obviously I get only polylines sometimes not useful to be transformed into
polygons.
Is there a way to get smooth polygons from gdal_polygonize or polygons from
gdal_contour?
