. The facts have been checked with other GIS programs.

this means it only happens in qgis or in all the sw you have tested?

#2 Updated by monokultur - over 9 years ago

It only happens in qgis. All other gis programs are projecting the polygones at the right place.

The attached file shows some fields in north-east germany. you can check with the digital ortho photos (wms-server url: http://www.geodaten-mv.de/dienste/adv_dop) if they are at the right place (the photos are visible only at a certain scale)

In [[EPSG25833"httpspatialreferenceorgrefepsg25833] the x coordinates usually has only 6 digits Unfortunately what MV (and also Brandenburg) calls EPSG25833 is EPSG25833 with an offset of 33000000m (and formerly only 3000000m) On ["Hinweise Geowebdienste - GeoPortal Mecklenburg-Vorpommern"httpwwwgeoportal-mvdeland-mvGeoPortalMV_proddeGeowebdiensteHinweise_Geowebdiensteindexjsp#epsgportal this is called EPSG35833 and explictly marked as not OGC conformant I've also found ["sources]] that call this BBG:25833 and also have "our" definition of EPSG:25833.

I'm not sure how we should deal with this.

Is it possible to integrate EPSG: 35833 into qgis?

Does that help? E.g. it won't on OGC services that are advertised with EPSG:25833.

BTW which other softwares did you try this with?
