I have digitized some shapefiles (polygons) in QGIS. Some polygons have the CRS 5678 DHDN 3-Degree Gauss Kruger Zone 4 E-N and the rest have the CRS 4326 WGS84. The Project coordinate system is also 5678 DHDN 3-Degree Gauss Kruger Zone 4 E-N.
But I don't know why they match on the map.
Then I load the shapefiles into ArcGIS and because of the different coordinate systems they don't match there. I have tried anything (project, transform, reproject) and Google can't help me but I need the shapefiles to match in ArcGIS.
Can anybody help me?
