Digital boundaries enable users of mapping software to visualise areas of interest or to map data thematically. Digital boundaries for Urban Centres/Localities (UC/Ls) and for Sections of State (SOS) will be released on 30 September 2002. Digital boundaries for other hierarchies within the Australian Standard Geographical Classification (ASGC), 2001 Edition are already available. For users who do not have access to mapping software, full colour A3 maps of Statistical Local Areas (SLAs) for the ASGC 2001 Edition are available for purchase. These maps show all Collection Districts (CDs) within an SLA, as well as basic topographic detail such as roads, rivers and railways. Maps of individual CDs are also available. Maps may be purchased from the ABS Web Site. However, to order large numbers of maps (a service charge will apply), or to purchase digital boundary products, contact the National Information and Referral Service on 1300 135 070, email email@example.com.
