It was prepared by Technical Committee IST/36, Geogra
9、phic information. A list of organizations represented on this committee can be obtained on request to its secretary.Information about this documentBS 7666 was originally published over the period 1994 to 1996 in four parts.These four parts were revised separately over the period 2000 to 2002. During
10、 2004 to 2005, all the parts were revised together, with a new Part 0: General model for gazetteers and spatial referencing has been added. This provides a common structure for gazetteers of any class of geographic object.BS 7666 now comprises the following parts: Part 0: General model for gazetters
11、 and spatial referencing;Part 1: Specification for a street gazetteer;Part 2: Specification for a land and property gazetteer;Part 5: Specification for a delivery point gazetteer.These parts supersede BS 7666-1:2000, BS 7666-2:2000, BS 7666-3:2000 and BS-7666-4:2002. The new Part 0 has subsumed Part
12、 3: Specification for addresses. Part 1 has subsumed Part 4: Specification for recording public rights of way but in other respects is similar in scope to that published previously. The scope of Part 2 is largely unchanged. Part 5 is new in scope. Parts BS 7666-1:2000, BS 7666-2:2000, BS 7666-3:2000
13、 and BS-7666-4:2002 are now withdrawn. Thus Parts 3 and 4 will not form part of the standard although there will now be a Part 5. Renumbering has not taken place to avoid any confusion with the withdrawn standards.The main changes that have been made to this Part of the Standard are as follows:the s
14、tructure, content and terminology are made consistent with the new general model in Part 0;the addition of a requirement for gazetteer metadata;the addition of a facility for recording descriptive identifiers in multiple languages;the addition of a facility for classification of streets;the removal
15、of the tolerance attribute and the replacement of the spatial locator by a pair of extremity points;the addition of a facility for cross-referencing to other datasets;removal of the requirement for the identifier of an elementary street unit to be the coordinates of a reference point and replacement
16、 with a general identifier; the addition of a informative annex on Public Rights of Way;other minor changes in the light of experience of use. BSI 2006 iiiBS 7666-1:2006Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Its requirements are expresse
17、d in sentences in which the principal auxiliary verb is “shall”.Commentary, explanation and general informative material is presented in smaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not purport to include all the necessary
18、 provisions of a contract. Users are responsible for its correct application.Compliance with a British Standard cannot confer immunity from legal obligations.iv BSI 2006BS 7666-1:2006IntroductionStreets are defined in different ways by different people for different purposes, and references can be b
19、y name, number or description. In this part of the standard, a general, all-encompassing definition is taken. Different ways of referencing streets are specified. Individual streets may have multiple references, and streets may overlap.The intention of this part of BS 7666 is to enable the consisten
20、t definition of streets and their compilation into street gazetteers. This will be used for a range of purposes, including highways and streetworks management, property addressing and navigation. A street gazetteer will also provide the street referencing element of land and property gazetteers whic
21、h provide a definitive list of land parcels and properties, each uniquely identified.Data to be recorded about Public Rights of Way, previously defined in BS 7666-4:2002, is included as an annex to this part, and applies only to England and Wales. BSI 2006 1BS 7666-1:20061 ScopeThis part of BS 7666
22、specifies the data to be maintained in a gazetteer of streets, consistent with Part 0 of this standard. This enables 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 so that data
23、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: a) by ide
24、ntifying the end points of a street, and representing the street as a single line segment;b) by breaking the street at its intermediate junctions to create a set of constituent line segments, termed elementary street units;c) by describing the course of each elementary street unit.Each of these opti
25、ons is defined by a level of conformance to the standard. This part of BS 7666 is intended for use by those compiling street gazetteers for purposes of highways and streetworks management, property addressing and navigation. It does not provide a database design or a transfer format.This part of BS
26、7666 also specifies how additional information on Public Rights of Way may be recorded. This only applies to England and Wales.2 Normative referencesThe following referenced documents are indispensable for the application of this document. For dated references, only the reference cited applies. For
27、undated references, the latest edition of the referenced document (including any amendments) applies.BS 7666-0, Spatial datasets for geographical referencing Part 0: General model for gazetters and spatial referencing.BS ISO 639-2, Codes for the representation of the names of languages Alpha-3 code.
28、BS ISO 8601, Data elements and interchange formats Information interchange Representation of dates and times.3 Terms and definitionsFor the purposes of this part of BS 7666, the terms and definitions given in BS 7666-0 and the following apply.3.1 administrative areageographic area that may be either
29、:a) a highest level local administrative area, which may be a county, unitary authority, metropolitan district, council area (Scotland) or district council (Northern Ireland); or2 BSI 2006BS 7666-1:2006b) Greater London; or c) an island or group of islands.NOTE Examples of administrative areas are “
30、Gloucestershire”, “London”, “Shetland Islands” and “the Isle of Man”.3.2 coordinated pointdefined point, the position of which is recorded as a pair of coordinates relative to coordinate reference systemNOTE Examples are a pair of National Grid coordinates in Great Britain.3.3 designated street name
31、name for a street that has been allocated by a street naming authorityNOTE This can normally be identified by a name plate on the street. In some cases, there may be two designated street names, e.g. where there are multiple languages used.3.4 elementary street unitsubset of a street that forms a co
32、ntinuous length between adjacent junctions or other significant landmarksNOTE An example of a significant landmark is a marker of the boundary of a locality or town.3.5 localitylocal area identified formally or informally by a particular name where people live or where certain activities take place
33、that may form part of a town, or stand in its own right within the context of one or more administrative areasNOTE A locality may be a neighbourhood, suburb, district, village, estate, settlement, parish or industrial estate 3.6 public right of way PROWlegally defined route over land in England and
34、Wales along which any member of the public has the right to pass and repass3.7 streetway or thoroughfare providing a right of passage on foot, by cycle or by motor vehicle, or access to more than one propertyNOTE The term “street” is used throughout this standard to encompass the terms “street”, “ro
35、ad” and “thoroughfare”. A street may be the whole or a part of a highway, road, lane, footpath, cyclepath, square, court, alley or passage. Rivers, canals, waterways, railways and drives to a single property are not streets.3.8 street descriptiondescription, allocated by a street naming authority or
36、 highway authority, used to identify a street that does not have a designated street nameNOTE A street that does not have a designated street name does not normally have a street name plate. BSI 2006 3BS 7666-1:20063.9 street referencename, number or description that identifies a street or part of a
37、 street3.10 street naming authoritybody designated with the responsibility for naming all streets in a defined areaNOTE This is normally a district council, unitary authority, metropolitan district, or London borough including the City of London. It is not necessarily the highway authority.3.11 stre
38、et numberroad or route number allocated to a street by a relevant authorityNOTE Examples of a relevant authority are the Department for Transport, the Scottish Executive, the Welsh Assembly Government, Northern Ireland Roads Service and the local highway authority. Examples of numbered streets are “
39、A1” and “C1111”. A street may have more than one street number.3.12 towncity or town that is not an administrative area, or a suburb of an administrative area that does not form part of another townNOTE Examples of towns are “Luton”, “Gosforth” and “Ealing”.3.13 unofficial street namename by which a
40、 street is known, but which has not been designated by a street naming authorityNOTE Such a street name may cover part or all of one or several streets. Examples are “Lovers Lane”, “The Great North Road” and “The old A14”.4 Street gazetteer requirements4.1 Scope of gazetteerA street gazetteer contai
41、ns references to instance of streets within its territory of use. The following types of street may be included within the scope of the gazetteer:a) motorway;b) trunk road;c) classified (numbered or unnumbered) road;d) any other named or unnamed road;e) public right of way;f) any other way that fall
42、s within the definition of a street that is required to be included to meet a particular user need.NOTE A “virtual” street such as a high rise building, or a river, canal, waterway or railway should not be included in the gazetteer. An indoor street within a shopping mall may be included in a gazett
43、eer. 4 BSI 2006BS 7666-1:20064.2 Street references For every street, a street reference shall be given, in the form of either:a) the designated street name; orb) the street description if the street does not have a designated street name.NOTE 1 Additional street references in the form of a street nu
44、mber and/or an unofficial street name may also be included.NOTE 2 An individual street may have more than one entry in the gazetteer as a result of being referenced in several ways, and different street references may overlap, e.g. Ellesmere Road is part of the Great West Road .A gazetteer may also
45、contain details of the elementary street units, the individual lengths of street that make up the street. NOTE 3 A set of conformance levels for street gazetteers are defined in Annex A covering the optional requirements. Three levels of conformance are defined.The relationship between the street an
46、d elementary street unit is shown in Figure 1.Figure 1 Street gazetteer modelNOTE The diagramming convention used in this figure is explained in Annex B. Street Gazetteer is a specialization of a Gazetteer as defined in Part 0 of this British Standard. Street and Elementary Street unit are specializ

If unnamed, a roundabout may be included in the gazetteer with a description or may be regarded as part of one of the streets, usually the major street p
49、assing through or leading to or from the roundabout. Mini roundabouts shall be considered as part of all the streets in which they are situated. Where a street continues beyond a roundabout, it shall be considered as a single street with a single street reference, unless the street name or number changes at the roundabout. NOTE If elementary street units are recorded for a roundabout, then there will be one between each pair of adjacent streets coming into the roundabout. 4.4.2 Dual carriageway streetsA dual carriageway shall
