[Qgis-developer] OGRSpatialReference problem in QGIS

[Florian Hillen]

Hi Jürgen,

thanks for that workaround. It works good, but delivers the same WKT:

PROJCS["unnamed",
GEOGCS["unnamed",
DATUM["unknown",
SPHEROID["unretrievable - using WGS84",6378137,298.257223563]],
PRIMEM["Greenwich",0],
UNIT["degree",0.0174532925199433]],
PROJECTION["Transverse_Mercator"],
PARAMETER["latitude_of_origin",0],
PARAMETER["central_meridian",9],
PARAMETER["scale_factor",1],
PARAMETER["false_easting",3500000],
PARAMETER["false_northing",0],
UNIT["metre",1,
AUTHORITY["EPSG","9001"]]]
