Hi together, I have a bunch of German zip code area geocodes in WGS84 and managed to host this under SQL Server 2008. The data source is rather old and probably abandoned http://prdownloads.sourceforge.net/mapbender/plz.zip?download
I used the data in various overlay scenarios, for exercises : * KML file and tiles generated using FME 2008, visualized using GE and Virtual Earth * GPolygons drawn on Google Maps * Spatial data viewer in SQL Server 2008 All results do show a slight north easterly shift (~100-200 m), whereas the entire shape always seems to be consistent - means it always covers the expected area. I cannot provide a link, but screenshots of all scenarios, if required (~300k, therefore not attached here). Furthermore I have no doubt, that the projection is OK in all cases (proven with a GPS device for some discrete vertices). My suspicion is, that the coordinates, I'm using, have been falsified in some sort of coordinate transformation somewhere between the origination and my system. Is this "NorthEath" shift probably a known phenomenon for some kind of those transformations?
