    Directions for the Future of SDI Development
    RAJABIFARD, ABBAS ; Feeney, Mary-Ellen F. ; Williamson, Ian P. ( 2002)
    Understanding the role of Spatial Data Infrastructure (SDI) is important to acceptance of the concept and its alignment with spatial industry objectives. Much has been done to describe and understand the components and interactions of different aspects of SDIs and their integration into the transactions of the spatial data community. However, what fails to be received through these perceptions, is that the role SDI plays is by necessity greater than the sum of individual components of SDI and stakeholder groups.SDI is fundamentally about facilitation and coordination of the exchange and sharing of spatial data between stakeholders in the spatial data community. To this end, the authors propose that the roles of SDI have been pursued through different approaches: product-based and process-based. Both approaches have value, but contribute to the evolution, uptake and utilisation of the SDI concept in different ways. They provide different frameworks for dealing with SDI mandates for the objectives of spatial data access and sharing. This paper reviews the nature and concept of SDI, including the components, which have helped to build understanding about the importance of an infrastructure to support the interactions of the spatial data community. Several examples of how SDIs have been described are offered to aid understanding of their complexity. The need for descriptions to represent the conflict between the role and deliverables of an SDI and thus contribute to a simpler, but dynamic, understanding of the complexity of the SDI concept, are postulated. The transition between the understanding of SDIs from product-based to process-based approaches is investigated, with a review of the positions taken by current SDI initiatives throughout the world. A model of how these approaches provide a framework to meet the mandates of the relevant jurisdictions is proposed, and factors contributing to the success of such positions in the future are discussed.

    Fundamental partnerships driving Spatial Data Infrastructure development within Australia
    Warnest, Mathew ; Feeney, Mary-Ellen ; RAJABIFARD, ABBAS ; Williamson, Ian P. ( 2002)
    Recent models of Spatial Data Infrastructures (SDIs) are overly simplistic and fail to address the dynamic nature, complexity, inter- and intra-jurisdictional nature and important role of partnerships. There is a need by governments and administrators to better understand the complex nature of SDIs to facilitate implementation of this form of infrastructure in an information society. This paper aims to build upon current SDI research at local, state and regional levels to better understand the complex and multi-dimensional nature at a national level, while building onthe principles of Hierarchical Spatial Reasoning (HSR) theory. To date little work has been undertaken on mapping these partnerships particularly at the national level within a country that is a federation of states. This paper will introduce the notion that better understanding of the partnerships that support SDI will enable administrators of spatial information to implement this type of infrastructure into the future. The paper will also highlight new research being conducted by the Centre for Spatial Data Infrastructures and Land Administration at the University of Melbourne on the Australian SDI (ASDI) and the aims to develop a methodology to map the complex nature of national SDI (NSDI).

    Snapshot of SDI Development in Australia: Models, Partnerships and Lead Agencies Advancing Implementation
    Warnest, M. ; Rajabifard, A. ; Williamson, I. P. ( 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.

    From Little Things Big Things Grow: Building the SDI from Local Government Up
    McDougall, K. ; Rajabifard, A. ; Williamson, I. P. ( 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.

    Key Factors Influencing Regional SDI Development and Relevance to Global and Other Levels
    RAJABIFARD, A ; WILLIAMSON, IP (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.

    The Cultural Aspects of Sharing and Dynamic Partnershipswithin an SDI Hierarchy
    Rajabifard, A. ; Feeney, M-E. F. ; Williamson, I. P. ( 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.
