I have exported a part of the Map from www.openstreetmap.org as .jpg. As I opend it in ArcGIS and defined it in WGS 1984, it didn’t correspond with my other layers. It was too big and it was in the wrong place. My other layers are all defined in Gauss Krüger, but thqat shouldn’t be a problem since ArcGIS kann show bothe at the same time. What do I have to do that the OpenSteetMap shows at the right coordinates?

Firstly any image that you have exported is not in WGS-84 but rather will have been projected to spherical mercator (EPSG-3857, sometimes nicknamed EPSG-900913 as it's the same system used by GOOGLE).

Your main problem however is that JPEG files do not have a system to store the geographical information in maps. And I think only TIFF is the only raster file type have that ability (which you can't export hint to developers).

ArcGIS is therefore making up the geographical information when importing JPEG files, probably from the current view. There is probably some way of changing the layer (scaling, moving, rotating) so that it matches the other layers.

You can use OSM as a basemap in ArcGis or you can import an osm file.

Thank you!

I have the same problem with osm converted to shape in QGIS, ir won't re-project to the projection set by the other layers, as it should, at least in ArcGIS.

I wondered if you might know what was going on as I tell it to take the projection of the other layers, maybe QGIS doesn't handle this.
