Hi, I'd like to develop a ogr driver to create .map files used by WAsP <http://en.wikipedia.org/wiki/WAsP>
The .map files contains height contours and roughness zones, the former are linestrings with an height attribute, the later are linestrings that separate two adjacent polygons with a roughness parameter on the righ and left sides. An algorithm to create roughness zones from polygons with a roughness attribute would be useful: extract the polygon boundaries and output linestrings with attributes on the left and right sides. What driver would you recommend as a starting point to get the interface, the coding style and the error handling right ? Is the algorithm to create roughness zones from polygons (i.e. extract polygon boundaries and add left/right attributes) something that should be integrated in the driver, somewhere else or not at all in gdal ? Thanks, V. _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
