This part of BS 7666 specifies the data to be maintained in a gazetteer of streets, consistent with BS 7666ā€‘0, enabling different users of street information to use the same data with consistency of content, accuracy, currency and format. Different ways of referencing a street are defined to ensure that data can be accessed by street name, description, route number, unique reference number or external cross reference.

This part of BS 7666 also specifies the means of representing the geometry of the street in terms of coordinates. Three ways are allowed for this with successive levels of detail by:

  1. identifying the end points of a street, and representing the street as a single line segment;

  2. breaking the street at its intermediate junctions to create a set of constituent line segments, termed elementary street units; and

  3. describing the course of each elementary street unit.

Each of these options is defined by a level of conformity to this British Standard.

This part of BS 7666 is intended for use by those compiling street gazetteers for the purposes of highways and streetworks management and property addressing. It does not provide a database design or a transfer format.
