Spatial data-sets for geographical referencing - Part 4: Specification for recording public rights of way Executive summary Geographical referencing of spatial-data sets for recording public rights of way. Abstract This part of BS 7666 specifies data to be recorded for public rights of way (PROW) in England and Wales. This British Standard is applicable in principle to other countries and regions but may require modification to accommodate local requirements, such as grid referencing in Northern Ireland. This standard specifies ways of referencing a public right of way so that data can be accessed by name, description, route number or unique reference. It also specifies the means of representing its spatial location. A format is also specified in the form of a logical data model for recording a set of other related data such as the surveying authority and the event history. This standard specifies what needs to be recorded for assessing or verifying the quality of the data. BS 7666-4 specifies the form, content and internal relationships of a spatial data-set for geographical referencing of PROWs to: a) optimize the use of resources involved in the design, compilation and use of such data-sets; b) permit the ready exchange and aggregation of such data-sets from several sources; c) facilitate the design of common information systems, which may be databases or Geographic Information Systems; d) enable different users of the same data to use it with consistency of content, accuracy, currency and format. PROWs defined within relevant parliamentary acts are those maintained by highway authorities in the discharge of their statutory duties. This standard is therefore directed toward developers and users of PROW spatial data-sets in their professional work, such as those working within leisure and recreational management or loca...
