Taka, OGR hasn't been properly tested on "real" GML3L0 files and there may well be lots of GML3 constructs that are legal but not recognised by OGR. Could you submit a bug report with the files in question in the OGR bugzilla? I can't promise to fix it quickly, but I hope to eventually. http://bugzilla.remotesensing.org/enter_bug.cgi?product=GDAL&component=OGR_SF Best regards, -- ---------------------------------------+-------------------------------------- I set the clouds in motion - turn up | Frank Warmerdam, [EMAIL PROTECTED] light and sound - activate the windows | http://pobox.com/~warmerdam and watch the world go round - Rush | Geospatial Programmer for Rent
