[Qgis-user] Projection not recognised EPSG:31259

[Helmut Kudrnovsky]

hi Roland,

ArcGIS 9.3 doesn't include the towgs-paramater in the prj-file.

maybe the original definition of a prj-file doesn't include the towgs-parameter, but gdal/ogr needs this information for a correct gdal-warp. 

I know from the ESRI-side that you have to define this parameter manually for a correct on-the-fly-reprojection, the same for GRASS, because there are not unique towgs-parameter in the epsg-db. it depends from the purpose of the data.

best regards
Helli
