12、ncontrolled Copy, (c) BSI ii BSI 1996 BS 7666 : Part 4 : 1996 Foreword This Part of BS 7666 has been prepared by Technical Committee IST/36. It has been developed by the National Land and Property Gazetteer Working Party, sponsored by the Local Authorities Geographic Information Advisory Group, thro
13、ugh the Local Government Management Board. BS 7666 comprises four Parts: Part 1 Specification for a Street Gazetteer Part 2 Specification for a Land and Property Gazetteer Part 3 Specification for addresses Part 4 Specification of a data-set for recording public rights of way Part 1 specifies a uniq
14、ue alphanumeric code for streets, and specifies that a street has to be located by a maximum of three location fields. Parts 1, 2 and 3 specify references for particular basic items of geographic data, and introduce the requirement for addressing. Part 3 specifies a general address structure. Part 4
15、 specifies the format for a data-set for recording public rights of way. Public rights of way (PROW) are routes over land in England and Wales along which any member of the public has the right to pass and repass. Designated local authorities have a statutory duty to record these in the form of Defi
16、nitive Maps and Definitive Statements. The aim of this specification is to identify the form, content and internal relationships of a data-set for recording public rights of way in order: a) to save time for any organization involved in the design, compilation and use of such data-set; b) to permit
17、the ready exchange and aggregation of such data from several sources; c) to facilitate the design of common information systems, which may be databases or geographic information systems. It has been assumed in the drafting of this British Standard that the execution of its provisions is entrusted to
18、 appropriately qualified and experienced people. Compliance with a British Standard does not of itself confer immunity from legal obligations.

Examples of PROW furniture are stile, fingerpost, steps. 1.3.15 PRO
33、W link A continuous subdivision of a PROW. NOTE.

37、Conventions used in this Part of BS 7666 The concepts, terminology and diagramming standards used in this Part of BS 7666 are based on the Structured Systems Analysis and Design Method for logical data modelling in accordance with BS 7738. Entities are denoted by boxes. The conventions shown in figu
38、re 1 apply in figures to identify relationships. In the tables, Man implies a mandatory item and Opt implies an optional item. One - one Relations One - many Mandatory Optional Optional/ mandatory Entity Figure 1 Explanation of figure conventions Data formats are defined by an A, D or I character to
39、gether with a number. A denotes an alphanumeric attribute, I an integer attribute and D a decimal attribute. NOTE.
