Geographical objects are defined in different ways by different people for different purposes. References can be by name, number or description. The BS 7666 series, produced to help standardize the referencing and addressing of geographical objects, has recently been revised.
BS 7666 Spatial datasets for geographical referencing identifies some types of spatial references, and provides a way of cross-referencing between datasets collected using different types of spatial references.
Please note:
These revised parts supersede BS 7666-1:2000, BS 7666-2:2000, BS 7666-3:2000 and BS-7666-4:2002. The new Part 0 has subsumed Part 3: Specification for addresses. Part 1 has subsumed Part 4: Specification for recording public rights of way, but in other respects is similar in scope to that published previously. The scope of Part 2 is largely unchanged. Part 5 is new in scope.
Parts BS 7666-1:2000, BS 7666-2:2000, BS 7666-3:2000 and BS-7666-4:2002 are now withdrawn. Thus Parts 3 and 4 will not form part of the standard although there will now be a Part 5. Renumbering has not taken place to avoid any confusion with the withdrawn standards.

BS 7666-0 defines the essential components of a gazetteer of geographic locations and provides a general model of spatial references based upon named spatial units in the United Kingdom. It defines the attributes of each geographic location to be recorded in a gazetteer, and the metadata associated with the gazetteer.
