I have exported a couple of sections of the OSM Map using the export tab and saving as a Mapnik image. I would now like to use these images in ArcGIS. In ArcGIS I have created a point layer showing the map sections corner points (in WSG84). To my surprise the map sections didn't correspond with my corner points. The map sections have the form of a square, the corner poitns on the other hand a rectangle. In both cases I used the exactly same coordinates. Does anybody have an idea what the solution could be?

The Mapnik image is generated using the Spherical Mercator projection. You have to set your ArcGIS to use that, not WGS84. The projection uses the codes EPSG:3857, sometimes also EPSG:900913. In older ArcGIS systems you might have to use ESRI:102100.

ESRI should handle conversions on the fly, why does it not reproject the osm data to the projection of the project I had set the layer to convert to?
