Hi Ben,
this is now the resumption of my second projection problem out of my forum request
"Change the projection of a google map"
which I have closed today. Here you can read my last answer to this request.
I have still the problem to project my vector layer upon the google layer. There is a south shift in my vector layer (epsg 31467) of 10 km. With my vector data from a surveying project in Switzerland I get a south shift of 40 km (epsg 21781).
You have given me the coordinates of my example location (highway cross in the north east of the german city Ulm) in decimal degrees.They are correct.
I gave you the coodinates in degree/ minutes/seconds and I'm sorry with a mistake in the latitude (46<-->48)
The right location ist 10 07 11, 48 27 50 and this is also correct. So both coodinates pairs, yours and my, are correct and describe the same location.
Also my coordinates, DHDN GK3, epsg 31467 (right 3582600, upper 5370300) describe the same location.
You can examine the german coodinates with the viewer of the survey agency. Look to the city Ulm and you will see the highway cross at the upper right of the city. I send it via email.

I guess that their must be something wrong with the north shift of the geodaetic datum in epsg 31467. As GoogleEarth shows the right location in degrees.
