I have a postGIS database in SRS 4326 (WGS84) with several Europe layers working well, but when I load a shapefile projected to the same SRS with QGIS, the layers don't match.

To explain it better I've made two screenshots: The pink one are the German postcodes from my postGIS database, that are matching with all the rest of my data enter image description here

The second one, green polygons, are German postcodes too, but from a shapefile. Both of them are in WGS84 (EPSG:4326, I've reprojected it with QGIS, and shows it in layer propperties). I've marked the coordinates below, to see that the it seems that the second one's coordinates are not correct.

Some Idea that how could I fix the green dataset to overlap with the rest? (pink) The source of the green dataset is this URL: http://arnulf.us/PLZ

Thanks!

The second dataset is definitely not WGS84. The East coordinate is negative, which is not possible for Germany.

The dataset comes without a .prj file, so you have to assign EPSG:4326 with Set CRS for Layer. Reprojecting is wrong, if you do not have the correct starting CRS.

This is my import of the shapefile:

  • Thanks. I've copied the .prj file from the first to the second one and renamed it, and now it overlaps perfectly. – Pablo Pardo Apr 11 '14 at 23:37
