Street

A Street feature extends and specialises the Road feature and in the Path Network product they will only represent Streets made up of PathLinks. A Street feature is populated from the National and Scottish Street Gazetteers and will exist where their Elementary Street Unit geometry has been matched to only PathLinks. They will represent either the complete Street or a section of a Street within an Administrative Unit, Town, or Locality and provides additional information about who is responsible for its naming and or numbering. A PathLink can be referenced by multiple Street features.

The Street extends the Road feature to provide the additional attribution required to adhere to BS 7666:

  • USRN: The Unique Street Reference Number is the unique and persistent identifier of a Street assigned by the Roads or Highway Authority.

  • Street Type: The type of Gazetteer record for which the USRN relates. It is mandatory for all USRNs to be assigned a Street Type.

  • Operational State: Indicates whether the Street is proposed, under construction, open, or closed (permanently or temporarily).

  • Responsible Authority: Reference to the authority which performs an administrative function – notably naming and numbering.

A Street will split when it crosses the boundary of an Administrative Area where the local maintenance responsibility changes. A Street could also split at a town or locality boundary to allow properties to be located uniquely upon a street via a unique identifier (i.e. USRN).

In the definitions below, users should read the term Highways as Roads when applied to streets in Scotland.

Street Attributes

Any road, footway, path, cycletrack, track or passageway that forms a highway. A highway represents individual subsections of Road which are managed (naming/numbering) by a specified responsible authority.

  • Constraints: A Street shall have at least one of designatedName (Type 1), descriptor (Type 2), nationalRoadCode (Type 3), or localName (Type 4). If a Street has a descriptor, it shall not have a designatedName.
