Contents >> 12. ASGC-related material and products

The ASGC manual is essentially a reference document. Consequently, additional and more specialised ASGC-related material and products are needed to assist application of the ASGC to statistical work. Many of these materials and products are available for sale to ABS clients, as well as for use by ABS personnel. The following is a listing of some of the more important types of related material and products.

ASGC-RELATED PRODUCTS AND SERVICES

National Localities Index (NLI)

The NLI (Cat. no. 1252.0) is a coding tool designed to assist users assign the ASGC Main Structure codes to street address information. Once coded to the ASGC Main Structure direct comparisons to other ABS statistical information may be made. The NLI is updated regularly and maintained in accordance with each edition of the ASGC.

The NLI consists of two parts - a Localities Index and a Streets Sub-Index. The Localities Index contains a list of all Localities in Australia. In broad terms, a Locality is a place where people live or work - or say they live or work. Localities are assigned their full ASGC Main Structure code (i.e. S/T, SD, SSD and SLA codes). The majority of Localities lie wholly within one SLA but where they are split between two or more SLAs, street information is recorded in the Streets Sub-Index.

Two products are available: the Index files and the NLI Coder. The Index files are produced as ASCII, comma delimited text files, of fixed field lengths suitable for loading into micro or mainframe computers. The NLI Coder is a standard 16 bit Windows application that provides an easy to use search engine which enables the user to assign an ASGC code to individual addresses.

Maps and digital boundaries
