[gdal-dev] Interlis driver does not polygonize anymore

[Stefan Ziegler]

Perfect! Thanks.

Did I get it right: If I want the polygon from an "AREA"-table I need to
explicit request the polygon geometry? From my point of view the point
geometry from an "AREA"-table is only there to join the attributes to the
polygons.

regards
Stefan
