InterestMap is derived from the Ordnance Survey Points of Interest database covering Great Britain (not including the Isle of Man, Northern Ireland, Eire and the Channel Islands). It consists of a vector layer of points indexed on record name for use with the Find command in a GIS, all highlighting location and function information, (classified into more than 600 individual classifications from more than 150 different suppliers) and with a postal address for all postally addressable points.
