The real difference between these projections is in the order of coordinate axis and it can be queried from the EPSG database: This one is Northing-Easting system http://epsg-registry.org/export.htm?wkt=urn:ogc:def:crs:EPSG::3042 But this one is Easting-Northing system http://epsg-registry.org/export.htm?wkt=urn:ogc:def:crs:EPSG::25830 Mixing those two may cause problems for example when data are exported into GML format. -Jukka Rahkonen- -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Why-QGIS-change-the-SRS-tp5308203p5314438.html Sent from the QGIS - User mailing list archive at Nabble.com. _______________________________________________ Qgis-user mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user
