Update: Bing Maps and Ordnance Survey data in ArcGIS Server 9.3.1

Apparently it is a known problem for OS data to not line up with Bing Maps service and in order to get round this you have to re-project all your British National Grid data to the WGS 1984 Web Mercator (Auxiliary Sphere) coordinate system.  How rubbish is that!

Anyway this problem is apparently known to ESRI and it is apparently fixed in verison 10 (it was tested by ESRI support in a beta 10 version).  So I guess we will have to wait until thats out and a few service packs have been released until we can feel confident with rolling out version 10.

On that note I’ll talk about this issue in about another year to 18 months (I would have thought!)

    I have ArcMap 10, and still have a projection problem between Ordinance Survey Data and the both the “Bing” and “Imagery” baselayers.

    The only solution I’ve found is as you describe; to export the ordinance survey data into the Bing coordinate system. This is frustrating, as my data needs are constantly changing, and it would be much simpler to reproject a single image rather than all of my changing shapefiles.

    If you come up with an alternate solution, I’d be very interested!
