Learn about the ASDI, Commonwealth needs for spatial data, catalysts for action, current initiatives, and compliance topics in a comprehensive overview. Discover the institutional and policy status, clearinghouse developments, current GIS web mapping initiatives, and the journey towards a fully functional ASDI. Explore the clearinghouse standards, metadata, and evolving data access landscape in this insightful presentation.

TOPICS • Background to ASDI • Commonwealth needs for spatial data • Catalysts for action • Current ASDI related initiatives • Summary
Background to ASDI • Comparison to US Initiative • Principle & Elements the same • No Executive Order - More cooperative • State / Federal partnership • Responsibility • ANZLIC (Nov 1996) • Commonwealth AUSLIG / CSDC
Commonwealth Needs for Spatial Data • Most Commonwealth Agencies need for spatial data to support their core responsibilities • Data is often held by other Commonwealth, State, Local Govt & private organisations • The current approach • The emerging direction
Catalysts for Action • International trends & Emerging technology • Prime Minister’s directive to provide government services online by June 2001 & online strategy encouraging interoperability. • Current projects (Coastal Atlas, NLWRA, Oil spill response atlas, MDBC - all use multi jurisdictional data)
Institutional / policy status • Each of the 9 Australian jurisdictional govts have coordinating arrangements • Together these comprise ANZLIC • ASDI is a combination of jurisdictional SDI’s to a level of standard. • Policies and practices are similar but different
Institutional / policy status • Conformity • Metadata standard (ASDD) • Custodianship guidelines • Differences • Pricing policies (new Cth policy) • distribution arrangements • Data standards
ASDI Compliance • Concept of a “scoreboard” developed by ANZLIC • An audit program has commenced in the Commonwealth. • 7 datasets audited to date • (see handouts)
Current Clearinghouse Initiatives • AUSLIG / CSIRO Clearinghouse Concept Architecture Consultancy • Australian Web Mapping Consortium and the Open GIS. • Trial projects • Commonwealth Clearinghouse Trial (ICMISS) • IMROC Project • ASDD Developments
Current InitiativesClearinghouse Concept Architecture • General acceptance in CSDC of the MODEL described by CSIRO • An access mechanism to a distributed network of fundamental data maintained by custodians & linked by common standards and protocols. • More work required on some of the standards - which ones?
Current Initiatives Open GIS Web Mapping • Background. • Developed a interoperable test bed and demonstrated at OGC Oct 99. • Resulted in a number of web mapping specification standards ( Get…..) • Consideration now being given to an Australian OGC SIG to continue involvement.
Current InitiativesCommonwealth Clearinghouse trial • A 6 month trial will be undertaken commencing this month. • AUSLIG, AGSO, AHO, BRS, MDBC, AODC • Trialing CSGI brokering protocol using OGC standards to serve data and provide services in a distributed environment. • Results of trial made available
Current Initiatives IMROC System • Inner Metropolitan Regional Organisation of Councils awarded an AUSLIG ASDI Partnership Grant • Contracted CSIRO to implement a distributed mapping system • Uses the Clearinghouse architecture framework and SVG and other protocols to deliver a solution.
Current InitiativesASDD Developments • Current ASDD has 38,601 metadata entriescompatible with US system • All jurisdictions have a node (except Tas) • Some private sector nodes • ASDD nodes used as key directory for some applications. • Extensions being considered by AMWG as part of new Australian Profile of ISO Metadata std.
Clearinghouse Standards • A number of standards exist • ANZLIC Metadata (and extensions) • XML • SVG • Others are emerging • ISO TC211 • OGC “Get map”, GML, Catalogue Services • Broker / middleware CSGI & RSL
Summary • The ASDI promises a lot but need to develop the “glue” to connect SDIs • National projects can be the catalyst to make this happen • Various levels of compatibility • Policies and pricing • Metadata • Data • On line data access
