[gdal-dev] ogr2ogr: How can I get GML output file in 2D?

[kai.zimmerl at srv.se]

Thanks, Stefan, I tried it but it didn't help!
(I wonder what the 2.5D option is for since the output seems to default to 2.5D)

There is an option for 2.5D ("-nlt polygon25d"), so you can try to add parameter "-nlt polygon".
