ItemSnapshot of SDI Development in Australia: Models, Partnerships and Lead Agencies Advancing Implementation( 2002)Australia is entering a new era for spatial data infrastructure (SDI) demonstrated by the unification of prime sectors of the spatial information industry and a renewed Government focus on spatial information. A spatial information stock take is required to review progress to date and evaluate current directions. SDI is deemed essential for the provision of services to support modern society's information needs and can be considered in the same manner as other public service infrastructure such as roads and utilities.This paper will evaluate progress since the release of ANZLIC's (1996) model for a SDI for Australia and New Zealand, identify the agencies driving SDI in Australia and will highlight key initiatives contributing to the ASDI development. Selected countries with advanced National Spatial Data Infrastructure (NSDI) programs will also be discussed in relation to developments of the SDI model within Australia. The paper contributes to research conducted by the Centre for Spatial Data Infrastructures and Land Administration at the University of Melbourne on SDI and to a new project being undertaken to develop a methodology to map the complex nature of the institutional arrangements and partnerships that support NSDI with particular focus on the ASDI.

ItemFrom Little Things Big Things Grow: Building the SDI from Local Government Up( 2002)The successful building of a multi-jurisdictional SDI has the potential to deliver significant benefits to the community, business and government through improved access to a range of relevant geospatial data. An effective National Spatial Data Infrastructure (NSDI) requires the vertical integration of spatial data at all levels of government. With local government being a custodian of a number of key SDI data sets, its role is now recognised as crucial to the development of the State and National Spatial Data Infrastructures. This paper will investigate some of the technical and institutional impediments that must be addressed within local and state jurisdictions in order to realise these benefits. An overview of the current status of local-state SDI arrangements in Australia will be presented as a basis for discussion. A framework for the further investigation and research into these issues will be outlined and some suggestions for progress put forward.

ItemKey Factors Influencing Regional SDI Development and Relevance to Global and Other Levels(GSDI6, 2002)The challenge of designing, building, implementing, and maintaining an SDI draws on many different disciplines and requires examination of a large number of factors and issues. It is essential that SDI practitioners understand the significance of human and societal issues as much as technical issues, all of which contribute to the success of SDI developments. Key issues include sustaining a culture of sharing, establishing a common language, and maintaining reliable financial support. This paper presents and discusses major classes of factors which influence, or contribute to the development of a Regional SDI initiative together with recommendations to facilitate the development of Regional SDI initiatives. It is argued that the adoption and implementation of these recommendations can assist Regional SDI coordinating agencies to receive more support and speed up their progress in the development of SDI initiatives. This paper draws on research conducted by the authors in Asia and the Pacific region, based on the theory of innovation diffusion which provides the research framework. The results and lessons learned from this research can also be used and applied in other regions, and potentially other jurisdictional levels such as local, state, national and global.

ItemThe Cultural Aspects of Sharing and Dynamic Partnershipswithin an SDI Hierarchy( 2002)The need to create multi-participant, decision-supported environments to address the issues of sustainable development and improving the quality of life creates a growing need to organise data across disciplines and organisations through different forms of spatial data infrastructure (SDI). This infrastructure is fundamentally a concept about facilitation and coordination of the exchange and sharing of spatial data between stakeholders from different jurisdictional levels in the spatial data community. The concept is well explained as an integrated, multi-levelled hierarchy of interconnected SDIs based on partnerships at corporate, local, state/provincial, national, regional (multi-national) and global (GSDI) levels. The creation of such an infrastructure and understanding the role of dynamic partnerships within an SDI hierarchy are essential to develop any SDI initiative. This paper reviews the nature and concept of SDIs, including the SDI hierarchy, which has helped to build understanding about the importance of the relationships within different levels of SDI, to support the interactions and dynamic nature of partnerships between spatial data communities. The role that human nature plays in any endeavour based on interaction and sharing makes cultural and social factors within a business environment important to the acceptance of the SDI concept and its alignment with spatial industry objectives. Further, the importance of establishing a culture for sharing as well as understanding the dynamic partnerships necessary to support such a culture is highlighted, and three classes of factors influencing SDI development are identified. It is argued that the adoption and implementation of these factors and selection of a proper model for SDI development can assist SDI coordinating agencies to overcome the problem of low participation and speed up the progress in the development of SDI initiatives.
