PAI Tools have been developed to help you shift your data following the Ordnance Survey PAI Program.  These tools will help you transfer your data from pre PAI to post PAI so that any datasets that you have captured against pre PAI LandLine and OS MasterMap will now match up with post LandLine and OS MasterMap.

These tools are an extension to ArcMap therefore they can be used with ArcView, ArcEditor and ArcInfo.

Important Note: There are two current versions of the ESRI(UK) PAI Tools: PAI Tools 2.0 and PAI Tools 3.0. If you are runnning ArcGIS 8.x, you need 2.0; if you are running ArcGIS 9, you need PAI Tools 3.0.
