STREETS SUB-INDEX


The Streets Sub-Index contains records of street data for the split Localities listed in the Localities Index. This index enables specific Statistical Local Area (SLA) coding for split Localities where the street name and number are known.

STREETS SUB-INDEX FILE FORMAT

The standard Streets Sub-Index format is a comma delimited ASCII text file with fixed length fields and a record length of 102 characters.

FIELD NAMES AND DEFINITIONS

The following field names and definitions relate to the Streets Sub-Index.

The Streets Sub-Index is subject to rules governing data representation and these are explained in the section titled Other Rules Governing Data Representation in the NLI.

Locality Name

Locality Name is a key field which links the split Localities on the Localities Index to their appropriate street data on the Streets Sub-Index.

Link to Localities Index

The Streets Sub-Index contains the names of all split Localities together with their street data. Each street is recorded with the State/Territory (S/T) code and four digit SLA code to which it belongs. These codes in the street data reflect the S/T code and the last four digits of one of the Australian Standard Geographical Classification (ASGC) code fields for the relevant Locality in the Localities Index. For example:

From the Localities Index, Blessington is a split Locality.

S/T Code

The S/T code indicates the State or Territory in which the Locality and a street or part of a street exists.

SLA Code

The SLA code indicates the SLA in which the street or street segment exists. In the Streets Sub-Index only the S/T and SLA components of the ASGC code are held as this is sufficient to uniquely identify the appropriate SLA.

Street Name

This field contains the names of streets, roads, avenues, etc. found within the Locality. Significant residential buildings and properties have been included for some split Localities if considered appropriate.

Street Type

This field describes the Street Type that is linked to the Street Name field. Common street types have been abbreviated while lesser used ones are fully described. A full listing of the Street Types used in the NLI is detailed in Appendix 1. Where an abbreviation has been adopted for NLI purposes the full title is shown in brackets.

Street Direction

This field shows the geographic descriptor where it is part of the street name e.g. SMITH STREET NORTH will be represented as SMITH, ST, N.

The street directions used are:

(blank) = default
N = North
S = South
E = East
W = West

This field also shows a Multiple Occurrence flag where a street name occurs more than once in a split Locality and the streets lie in different SLAs. It flags each record of the street name.

M = Multiple Occurrence

Street Number Range

Where a street is wholly contained within an SLA the street number range is 0001-9999.

Where a street lies across an SLA boundary, a number range is displayed for the segments contained within each SLA. The number range indicates the lowest and highest numbers (inclusive) along the street for which each SLA code is valid.

Where a street crosses SLA boundaries and the street number range is unknown or, in the case of many rural roads, does not exist or cannot be determined from current sources, then the value of 0000-0000 is given for the street number range.

Odds/Evens/All Flag

This field flags whether all or specifically odd or even street numbers are included in the street’s number range for the SLA code.

O = odd numbers only
E = even numbers only
A = all numbers

Examples

Where a street is entirely within an SLA, the street number range is represented 0001-9999 A.

Where the odd side of a street is wholly within an SLA, the street number range is represented 0001-9999 O.

Where the even side of a street is wholly within an SLA, the street number range is represented 0002-9998 E.

Where the number range on the odd side of the street within an SLA is unknown, ambiguous, or does not exist, the street number range is represented as 0000-0000 O.

Where the number range on the even side of the street within an SLA is unknown, ambiguous, or does not exist, the street number range is represented 0000-0000 E.

Where the number range on both the odd and even sides of the street within an SLA is unknown, ambiguous, or does not exist, the street number range is represented 0000-0000 A.
