18. The NLPG and LLPG

7.1 Strata is responsible for maintaining address information relating to 3 authorities in the National Land and Property Gazetteer (NLPG). This is done by maintaining a Local Land and Property Gazetteer (LLPG) for each Council.

7.2 The LLPG and NLPG will be updated to include all authorised new street names, building names and numbering. The LLPG and NLPG are maintained in accordance with British Standard BS7666 “Spatial Data-sets for geographical referencing”.

7.3 The LLPG and NLPG are growing in importance as increasingly these databases are being used by many government agencies, including the emergency services. Strata is in the process of integrating the LLPG with its other property based information systems. All changes to, or additions of, addresses will be also be made in the LLPG. This information is then distributed internally within each Council and passed to the NLPG for National distribution.
