OTHER RULES GOVERNING DATA REPRESENTATION IN THE NLI
The NLI aims to assist users to code addresses to the relevant Australian Standard Geographical Classification (ASGC) Main Structure code. The many source materials which contribute to the Localities Index and Streets Sub-Index often represent Locality and Street data with a variety of spellings, punctuations and abbreviations.
Chapters 3 and 4 in this document describe what is recorded in each of the fields of the Localities Index and the Streets Sub-Index files. Other rules governing how source material should be represented are also applied to provide consistency in the NLI and these are set out below.
LOCALITIES INDEX
Rules applied to the Locality Name field
All Locality Names are in capital letters.
No punctuation is used.
An abbreviation, ST, is used to represent the word SAINT where it is the first part of a Locality Name. At all other times it is shown as a full spelling.
The words MOUNT, PORT and POINT are not abbreviated.
The abbreviations RAAF and RAN are used for Locality Names involving Royal Australian Air Force or Royal Australian Navy bases.
Locality Name qualifiers such as North, South, Lake, Island and the like are not abbreviated.
The Property Indicator field shows the P flag for Locality Names which in source materials are described as agricultural properties. Descriptors like Station, Homestead or Property are not used in agricultural property names.
Rules applied to the ASGC codes and the Major SLA name fields
All ASGC codes used in the NLI are consistent with the relevant edition of the ASGC.
All Major SLA names include punctuations, abbreviations, and spellings which are consistent with the relevant edition of the ASGC.
The Major SLA name is in capital letters.
STREETS SUB-INDEX
Rules applied to the Locality Name field
Data are consistent with the Localities Index Locality Name field.
Rules applied to the ASGC code field
The ASGC codes for State/Territory and SLA for each Street record are displayed. They are consistent with the relevant edition of the ASGC and the codes for the corresponding Locality Name in the Localities Index.
Rules applied to the Street Name field
The punctuation, abbreviation and word treatment rules applied to the Locality Name field also apply to the Street Name field;
In the case of streets such as 'The Parade', 'The Esplanade', etc. the whole name is included in the Street Name field. The whole name is also included in the Street Name field in the case of streets such as 'The Avenue of Honour', where the street type does not occur at the end of the street name (ignoring the street direction if it is present). In both cases the Street Type field is left blank.
The NLI aims to have an exhaustive listing of the street patterning for a split Locality. There are also other features that are included in the NLI Streets file; these are not exhaustively recorded, but are added ‘subjectively’ and include:
- walking tracks/4 wheel drive tracks/fire tracks
- rural property names
- shopping complexes/large buildings
- schools/hospitals
- retirement homes/hostels/caravan parks
- reserves/recreational facilities
- marinas/wharves/piers
Rules applied to the Street Type field
The Street Type field shows the P flag for features of a split Locality which in source materials include descriptors like Station, Homestead or Property. Those descriptors are not displayed in the Street Name field.
Street Type 'BLDG' is used to indicate a feature that is neither a street or a property. In most cases these will be buildings in the everyday sense, but it is also applied to features such as Airports and University Campuses which would not normally be considered buildings.
In the case of streets such as 'The Parade', 'The Esplanade', etc. the Street Type field is left blank. The Street Type field is also left blank in cases where the street type does not occur at the end of the street name (ignoring the street direction if it is present), for example 'The Avenue of Honour'. In both cases the whole name is included in the Street Name field.
