Hi there! After upgrading my QGIS rollout from 3.4 to 3.10 I try to implement our local gsb gridfile for layer transformations: DHDN GK3 (EPSG:31467) to ETRS89 UTM 32N (EPSG:25832).
Since Proj 6 (QGIS 3.10) the former method of just placing the .gsb to \share\proj and updating tbl_srs in \apps\qgis-ltr\resources\srs.db in order to make this transformation the default seems to be unsufficient now. The configurations do not show up when asked for datum transformation if several are available [1]. Is it correct, that the tranformations in this dialog are read from \share\proj\proj.db and therefore this is the place to add my configuration? I found that there is a record for the (not shipped) BWTA2017.gsb. in table grid_transformation of proj.db. So, do I just have to add a record to grid_transformation for my gridfile in the same way? What would be the correct parameters? Is there another table that has to be adapted to make it work? cheers Thomas [1] https://docs.qgis.org/3.10/en/docs/user_manual/working_with_projections/working_with_projections.html#datum-transformations _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user
