The One Scotland Gazetteer (OSG) is an address dataset that comprises up-to-date data, maintained by each of Scotland’s 32 local authorities.
The information stems from local authority functions, including Planning, Building Standards and Street Naming and Numbering which are the foundations for all address intelligence.
The local gazetteers are collated by the Spatial Information Service within the Improvement Service, where robust quality assurance is undertaken to ensure currency and consistency. Consequently, the OSG dataset adheres to nationally agreed conventions and is held in a standardised structure that conforms to the British Standard for addressing.
The OSG dates back to 2003, when the then Scottish Executive provided £7.5m of funding, along with £2.5m from Scottish local authorities, to create a national gazetteer which would support the delivery of modern public services in Scotland.
Crucially, the OSG holds the unique property reference number that provides a common thread that allows the linking of information held in disparate systems.
The OSG is made freely available to members of the One Scotland Mapping Agreement and is used throughout the Scottish public sector, including the emergency services, e-Planning, ScotLIS, the Energy Savings Trust, SEPA, myaccount, assessor and the electoral register.
In Scotland, the OSG forms the foundation for Ordnance Survey’s AddressBase product suite.
