Some time ago I wrote a program that would extract PushPin details (Lat/Long, Name, Information) from a Pocket Streets file exported from AutoRoute 2001. This worked fine until I found that later versions of AutoRoute exported an incorrect value for the Longitude of a PushPin.

I now know that the problem also exists in MapPoint 2004 Once again it is the Longitude value that is incorrect. I understand that, when the .PSP file is used with Pocket Streets, Microsoft transform the data so that it is correct. Does anyone know the transformation?

Ever hopeful
