14、09 Edition 1 3 Geographic information Addresses Part 1: Data format of addresses 1 Scope This standard specifies and defines the data elements, as well as the address types that can be constructed from the data elements for South African addresses. The standard further defines terms and definitions
15、related to addresses in South Africa. This standard is applicable to addresses covering the whole of South Africa. The standard applies to addresses that describe the physical location of a point of service delivery, and that could be geo-referenced. The standard includes definitions for address typ
16、es that are assigned by the official address issuing body (such as the street address type), as well as address types that are commonly in use (such as the farm and informal address types). 2 Normative references The following referenced documents are indispensable for the application of this docume
17、nt. All normative documents are subject to revision and, since any reference to a normative document is deemed to be a reference to the latest edition of that document, parties to agreements based on this document are encouraged to take steps to ensure the use of the most recent editions of the norm

These attributes are not part of the actual address but provide additional information a
29、bout the address. Even though this is a form of metadata, the attributes do not replace metadata as specified in SANS 1878-1 but rather complement it. The name shall be used unless the system cannot accommodate names longer than ten characters in which case the short name may be used. Annex A has a
30、summary table of the address attributes.(see table A1) 4.2 Geographical location attributes NOTE An address is exchanged as a point feature. Feature types during allocation and maintenance of addresses are given SANS 1883-3. 4.2.1 Coordinate reference system Definition Coordinate reference system wh
