Reading GML files containing object classes with multiple data types
|GML, map layers, QGIS
QGIS (QuantumGIS) 1.7.3 uses OGR/GDAL to read GML 3.x data files. I'm using this to display a GML3 data file. One object class in this GML file ("Roads") consists of multiple data types (points AND lines AND polygons). Apparently GML supports this... Instead of creating three map layers, the OGR import module suggests *one* map layer with data type "unknown", and subsequently reads the data only partially. The Roads are displayed incorrectly.
I'm not really sure whether this is an issue for GDAL/OGR or for QGIS, but the QGIS forum suggests contacting the GDAL mailing lists, since that's the import module they use for reading GML.
Many thanks in advance,
