Key public buildings in Great Britain
Geometry
Point
Data Sources
Data captured by OS field surveyors.
Completeness
Access Locations will be collected for key public buildings within a subset of Land Use Sites:
Hospitals
Stadiums and Sports Arenas – Typically those with a capacity greater than 5 000 people
Shopping Centres – Typically those with greater than 50 retail units
Railway Stations
Major Transport Interchanges – Typically airports, international ferry terminals, vehicular ferry terminals with a Land Use Site area greater than 1 000m² and bus / coach stations with a Land Use Site area greater than 5 000m²
Conference Centres – Typically sites whose primary function is to host formal discussions/meetings and exhibitions and with a capacity greater than 500 people
Concert Venues – Typically those with a capacity greater than 1 000 people
Thematic Accuracy
The classification of Access Locations is based upon ground survey collection of externally identifiable access locations.
Currency / Data Updates
Access Locations will be updated into the OS NGD where changes occur to topographic features following the standard revision policy for such features.
