ItemDirections for the Future of SDI Development( 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.

ItemSpatial data infrastructures: concept, SDI hierarchy and future directions( 2001)The world as we know it is changing. Economies world wide are undergoing a process ofprofound and continuing structural change, and the global village is becoming a reality driven byIT and communication technologies. With this in mind, many countries believe that they canbenefit both economically and environmentally from better management of their spatial data assetsby taking a perspective that starts at a local level and proceeds through state, national and regionallevels to global level. This has resulted in the development of the Spatial Data Infrastructure (SDI)concept at these levels.SDI is fundamentally about facilitation and coordination of the exchange and sharing ofspatial data between stakeholders from different jurisdictional levels in the spatial datacommunity. Understanding of its role and nature are important to the acceptance of the conceptand its alignment with spatial industry objectives.The aim of this paper is to present the nature and concept of spatial data infrastructures,including the SDI hierarchy, which have helped to build understanding about the importance ofthe relationships within different levels of SDIs to support the interactions and partnerships of thespatial data communities. Moreover, the paper will highlight the importance of sharing andunderstanding its special social system, followed by a discussion of the future direction of SDIs. Itis argued that by better understanding the future direction of SDIs, any SDI development can gainsupport from a wider community of both government and non-government data users andproviders.

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.

ItemAnticipating the cultural aspects of sharing for SDI development( 2003)The complexity of communications and relationships between sectors and agencies to achieve a common understanding of spatially related issues across a jurisdiction is paramount for any economy, management of the environment, social issues and security. On the other hand, 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. This paper reviews the role that human nature plays in any endeavour based on interaction and sharing makes cultural and social factors important to the acceptance of the SDI concept and its alignment with spatial industry objectives. Cultural aspects and social factors influence the complexity and dynamics of developing SDIs. Therefore, positioning to consider these aspects and factors are important elements in design and development of SDIs. Further, the importance of establishing a culture for sharing as well as understanding the dynamic partnerships necessary to support such a culture is highlighted. It is argued that by better understanding and promoting a culture for sharing spatial data, any level of SDI development can gain support from a wider community of both government and non-government data users and producers.
