Clearinghouse Model
The Australian Spatial Clearinghouse is an environment that facilitates access to data, products and services. It incorporates:
discovery, transfer and access facilities; legal arrangements; coordination and management functions; the spatial information commercial market place in which data is value-added and integrated to produce products, services and solutions.
State/Territory governments Federal Government
Through the OSDM
Facilitate implementation of a whole-of-government portal to fundamental spatial data Portal to provide a single approach to prices and licencing Portal will operate within the ANZLIC-defined national clearinghouse model and will be linked to the ‘Government Online’ network
Federal, State and Territory governments

Responsibilities for Clearinghouse Implementation - Nationally
The Australian Spatial Clearinghouse includes:
multi-jurisdictional data and products (formed by joining jurisdiction datasets to produce extended regional or national coverage); links to clearinghouse initiatives in the States, Territories and the Commonwealth; government agencies and private sector businesses that form the spatial information market place.
Participation in the OGC web mapping testbed project
States and Territories
Examples
Land Information System Tasmania (LIST), Virtual Victoria initiative, New South Wales Community Access to Natural Resources Information (CANRI) system
Geoscience Australia
Online download and e-commerce facilities in place, and major fundamental datasets online
Conclusion
There is a rapidly growing demand for efficient online access to fundamental spatial data in Australia and many other countries There are a number of good examples of public and private spatial spatial data clearinghouses around the world Although there are several good individual examples of clearinghouse implementation in Australia, a truly national solution has not yet arrived Australia started early in the development of the core clearinghouse elements of metadata and a distributed directory and these elements have been used extensively A national clearinghouse will need to involve both public and private sectors, and will need to link to regional and global implementations
