If it can be handled by the GML driver except for the geometries, you could probably add a special processing like done for AIXM ElevatedPoint. Have a look in ogr/ogrsf_frmts/gml/gmlhandler.cpp at : - ParseAIXMElevationPoint() : transform a custom geometry format into standard GML - where it is called : line 1498 - GMLHandler::IsGeometryElement() > > Thanks, Martin > > [1] http://codesynthesis.com/pipermail/xsd-users/2016-January/004755.html -- Spatialys - Geospatial professional services http://www.spatialys.com _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
