Hello,<br>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.<br>
Is there a way to get smooth polygons from gdal_polygonize or polygons from gdal_contour? <br clear="all"><br>-- <br>--------------------------------------------------------------------------<br>Carlo A. Bertelli<br> Charta servizi e sistemi per il territorio e la storia ambientale srl <br>
