TOPICS

  • Background to ASDI

  • Commonwealth needs for spatial data

  • Catalysts for action

  • Current ASDI related initiatives

  • Summary


Background to asdi
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
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
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
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 status1
Institutional / policy status

  • Conformity

    • Metadata standard (ASDD)

    • Custodianship guidelines

  • Differences

    • Pricing policies (new Cth policy)

    • distribution arrangements

    • Data standards


Asdi compliance
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
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 initiatives clearinghouse concept architecture
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 clearinghouse architecture
Current Initiatives Clearinghouse Architecture


Current initiatives open gis web mapping
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 initiatives commonwealth clearinghouse trial
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
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 initiatives asdd developments
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
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
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
