5、ved by National Committee SABS SC 71E, Information technology Geographic information, in accordance with procedures of the SABS Standards Division, in compliance with annex 3 of the WTO/TBT agreement. This document was published in October 2009. SANS 1883 consists of the following parts under the ge
6、neral title Geographic information Addresses: Part 1: Data format of addresses. Part 2: Guidelines for addresses in databases, data transfer, exchange and interoperability. Part 3: Guidelines for address allocation and updates. Introduction The aim of the address standard is not to devise a new syst
7、em of addressing or to build a national address database, but rather to enable interoperability in address datasets, which will facilitate developing a national address database. This standard supports, a) the allocation and management of addresses, b) the recording and interchange of addresses, c)
8、the geo-coding and spatial representation of addresses, d) the delivery of services throughout South Africa, and e) the national developmental objectives.

13、SANS 1883-3:2009 Edition 1 2 This page is intentionally left blank SANS 1883-3:2009 Edition 1 3 Geographic information Addresses Part 3: Guidelines for address allocation and updates 1 Scope This part of SANS 1883 provides guidelines for the allocation and maintenance of addresses for the official a
14、ddress types specified in part 1 of this standard. It gives rules, orientation, advice and recommendations relating to the use of part 1. It applies to any area where the development correlates with the underlying cadastre, including previously unaddressed areas. In terms of address allocation the g
15、uidelines specify how addresses should be arranged geographically. For address maintenance the guidelines specify how addresses should be updated in the case of name changes, boundary changes, subdivisions, and consolidations. Existing addresses should not be affected by the adoption of these guidel
16、ines. However, where possible, a link between an existing address (not complying to the standard) and a new address (complying to the standard) should be kept. The guidelines are written with the objective of address data exchange and interoperability, and thus they do not specify how the data is ma
17、naged and maintained on a day-to-day basis. The process of allocating and updating erf numbers falls under the Chief Surveyor General, and is not covered in SANS 1883, even though erf numbers appear as data elements in SANS 1883. 2 Normative references The following referenced documents are indispen
18、sable for the application of this document.

27、t name and street name type 4.1.1 Street names Mandatory guidelines a) Public street names have to be assigned according to the SAGN regulations. b) Street names cannot be duplicated (or similarly spelt or phonetically similar) within at least a 5 km radius or within the suburb or adjoining suburb.
28、All the recorded extensions of a suburb, e.g. Garsfontein Ext 1, Garsfontein Ext 2, etc. constitute the same, single suburb (in this case, Garsfontein). The street name has to be unique irrespective of the street type, i.e. Fourth Avenue and Fourth Street within a radius of at least 5km are consider
29、ed to be duplicate street names. NOTE The term suburb is broadly interpreted as a land boundary with a single name. Thus suburb could refer to Garsfontein as explained in rule 2 of Error!

30、ars on the approved SG general plan or similar documents has to be used as the primary street name. Other versions of the name that are used by the public are catered for as alias or alternative street names, i.e. the address official status is set to Alternate Official (refer to the status in SANS
31、1883-1). If a street name appears in more than one language on approved SG general plans, the English name is used as the primary street name. d) If a street name does not appear on the approved SG general plan, the municipality has to assign a street name according to the guidelines in this section
32、. e) If the street name is an ordinal number, it should be written out, i.e. Fourth Street (and not 4th Street). f) A street name can only change at an intersection. (see figure 1 to 2). g) A directional or modifier can only be added if there is a man-made barrier between the street and its extensio
33、n, such as Church Square is between Church Street and Church Street West.

35、ctional title or other private complexes) should be attempted to be assigned according to the SAGN regulations. b) Street names should be as short as possible to make it practical to display on a name board. A rule of thumb is a maximum of 20 characters for the street name. c) Preferably street name
36、s within an area should follow a theme. The theme is not prescribed. d) If a street is extended in such a way that negative street numbers have to be assigned, a new street name should be allocated. 4.1.3 Street names types Mandatory guidelines a) Only street types as prescribed by the SAGN can be u
37、sed. b) The language attribute of an address indicates the language of the official address, i.e. the status is set to Official. Street types in alternative languages can be carried as alias or alternative street types, i.e. the address official status is set to Alternate Official (refer to the Stat
38、us in SANS 1883-1). 4.2 Street numbering 4.2.1 Mandatory guidelines a) Even on the one side, odd on the other side b) Within a municipality the even numbers always have to be assigned on the same side (e.g. Eastern side), and the odd numbers on the other side (e.g. Western side). c) In a bulge stree
39、t, street numbers are assigned sequentially in the even or odd sequence.

40、41816753113119Figure 4 Street numbers in a bulge d) A municipality should have a set of rules according to which the street number origin (i.e. the lowest street number for the street) and direction of increment are assigned consistently so that only positive integer numbers are assigned as street n
41、umbers. e) Only positive numbers are allowed as street numbers f) Street numbers should be in sequential order for a street with a particular street name within a municipality. If it is not possible to continue in the sequential order, e.g. where the street extension would require negative numbers,
42、either a new street name should be assigned or existing street numbers have to be re-assigned. (see figure 5) LANGERUGRIETVALLEIWISTERIA0 .009 .018 .027KilometersLegendCadastreStreet6210951Figure 5 Extension of Rietvallei would result in negative street numbers and thus requires a new street name or
43、 re-assignment of street numbers SANS 1883-3:2009 Edition 1 9 g) Suffixes to street numbers, e.g. 4A, are discouraged, but allowed where necessary. h) Street numbers have to be assigned regardless of the development or lack thereof along the street, e.g. street numbers are also assigned to open spac
44、es, vacant land, parks, etc. i) Street numbers in a cul-de-sac could be assigned sequentially or as in any other street. j) For a property that has more than one street frontage, street numbers are reserved along all street frontages, but one of them is assigned as the official street address. k) Th
45、e municipality allocates a street number to the entrances of a private development such as a sectional title complex or security estate. 4.2.2 Recommended guidelines a) Preferably street numbers should be assigned in increasing order from West to East, and North to South.

The increments could omit certain numbers. For example, in fixed intervals of 16m for large properties the numbers 2,6,10,14 etc could assigned.
48、The street number closest to the entrance of a particular property is used as the street number in the official address. This interval and regular increment should prevent the need for suffixes. (see figure 8) Figure 8 Assigning street numbers in regular increments omitting certain numbers c) Prefix
49、es to street numbers, e.g. A4, are not allowed. d) Street numbers on private streets should be in line with the guidelines in this document. e) If a previous T-junction is extended, the street numbers should follow a logical sequence if the street name is retained 5 Guidelines for informal address allocation Addresses in areas that are not covered in one of the previous sections, should be assigned according to the guidelines SA Post Office guidelines for rural addresses as provided in annex A. 6 Metadata Metadata should be maintained a
