Last days we made really huge progress improving CRS handling. One of the changes was JEF's less restrictive CRS interpreting: http://trac.osgeo.org/qgis/changeset/15361 . If nobody disagree, I'd propose to extend it also for the +towgs84 parameter.
In the resources/srs.db we have added a number of CRSes in both versions: one with +towgs because of reprojection accuracy and one without because of compatibility with layers produced by most software. For example: epsg 2180 and 42180. It would be much simpler for users if we could keep the full projStrings (with the parameter) only and Qgis was able to recognize layers with missing parameter as them. We would be also able to remove the odd CRSes and decrease the difference between our crs database and the original proj4 one. _______________________________________________ Qgis-developer mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-developer
