Address Base developing a unique national address gazetteer

Address. Base™, developing a unique national address gazetteer Nick Turner, Address Migration and Business Development Manager, Ordnance Survey Carsten Rönsdorf, chair British Standards Institution Committee for Geographic Information

Part 1: Standards as the basis for addresses Carsten Rönsdorf, chair British Standards Institution Committee for Geographic Information (IST/36)

Agenda • What standards bring to the table • British Standards Institution IST/36 committee • Snapshots and Lifecycles • BS 7666 – high level introduction • Other address specifications • Data models and GML

Ad es dr s? se

Why standards • Apply to actual or potential problems • For common and repeated use • Aimed at achievement of optimum degree of order in a given context • Successful standards need to be: • wanted, usable (implemented) and used • beneficial and impartial • up-to-date and have wide application • Conformance can be tested / certified • Can provide investment security • Contain best practise • Often available on RAND [Reasonable and Non-Discriminatory] terms on a royalty-free basis (excl. BSi, ISO etc)

The IST/36 committee • Government and industry representatives and co-opted experts • Process and transparency • Maintains BS 7666 • UK representation in to ISO and CEN committees • ISO TC 211 foundational conceptualisation of geospatial data • CEN TC 287 focussing on how to use standards • TR 15449 -x: how to use OGC and ISO standards to create a Spatial Data Infrastructure • Profiles: specialisations of standards, i. e. to make an international standard more relevant in a national context • Gemini 2. 1 UK metadata standard for GI, based on ISO • ISO/CEN liaison with the Open Geospatial Consortium

Property / address life cycle

Some BS 7666 principles • Geographical scope to cover all of UK, Isle of Man and Channel Islands • Meet national language requirements • Enable cross-referencing with other data • Maintenance of relationship between streets and BLPUs • difficult cases to be clarified • allow for those not fitting general model • Separate implementation guidelines available

BS 7666 structure ISO 19112 Spatial referencing by geographic identifiers BS 7666 - 0 General model BS 7666 -1 Specification for a street gazetteer Annex PROWs BS 7666 -2 Specification for a land & property gazetteer Annex Specification for Addresses BS 7666 -5 Specification for a gazetteer of delivery points

Part 0: General model • Provides a general model of spatial references based upon named spatial units • Defines the essential components of a gazetteer of geographic locations • Provides structure for gazetteers defined in other parts • Based upon ISO 19112 Spatial referencing by geographic identifiers

Location records • mandatory • optional • identifier • alternative identifier • entry date • classification • update • external cross-refs • start date • end date • position • current state & date • spatial reference • extent • administrator • related location • parent/child locations

Data quality report • lineage • currency • positional accuracy • attribute accuracy • Completeness All relating to ISO 19113/4 -> 19157

Role of standards in the creation of Address. Base. TM • Different address registers with their own identifiers • Extensive data matching exercise • Both main input datasets contained a BS 7666 structured address • Integration of Scottish data with current database (England Wales only) • Address. Base premium implements BS 7666 • European Inspire address specification (mandatory for public sector providers of addresses) is also built on 19112: standards facilitate mapping processes
