Australian Spatial Data Directory

what is the ASDD?

The Australian Spatial Data Directory (ASDD) is an online directory that enables people to discover what spatial data is available throughout Australia. The information contained in the directory is called metadata. Metadata is a summary document about the dataset, including the geographic area that the dataset covers, the custodian, who to contact to obtain a copy of the dataset and other useful information that helps people decide whether or not the dataset is useful for their particular purpose.

The ASDD was launched in 1998 and now contains over 30,000 entries held on 24 nodes around Australia. The ASDD allows the concurrent interrogation of the existing nodes by a user with an internet browser.

The ASDD provides a central access point over the internet to essential information about spatial data held at a variety of locations throughout Australia and New Zealand. This information is accessible on-line to people in industry, government, education and the general community.

The main entry point to the Australian Spatial Data Directory can be found at <www.ga.gov.au/asdd/>.

a partnership approach

The ASDD is a national initiative supported by the Australian (Commonwealth, States and Territories) and New Zealand governments through ANZLIC – the Spatial Information Council.

Geoscience Australia maintains the gateway to the ASDD on behalf of ANZLIC. Responsibility for the maintenance of the individual nodes lies with the relevant government and commercial organisations. Anybody can establish a node on the ASDD, but agencies with small holdings are encouraged to use the hosting services of one of the existing nodes.

To register a node on the ASDD, contact the at Geoscience Australia.

review

A review of the ASDD was commissioned by the ANZLIC Spatial Data Infrastructure Standing Committee in October 2001. The findings of this review were published in the report Audit of the Australian Spatial Data Directory.

Most users of the ASDD expressed satisfaction with the information provided by the system. However, the audit report acknowledged that while a large number of datasets were listed on the ASDD, it was not fully comprehensive.

The ASDD is well supported by the environmental, land administration, land management, marine and natural resources communities. There is, however, little or no representation from local government, academia, private sector, utilities, social, health and emergency management.

what can you do?

You can help us make the ASDD more relevant to your needs by:

  • letting us know what datasets that may be useful to you but are not included on the ASDD
  • ensuring that metadata about spatial information already on the ASDD is up to date and accurate
  • including your metadata to the ASDD and
  • identifying ways to improve how you can discover information on the ASDD to meet your specific needs

Contact the national office or your metadata representative.
