    What will motivate local governments to share spatial information
    McDougall, K. ; Rajabifard, A. ; Williamson, I. P. ( 2005)
    Local government is a rich source of accurate and detailed spatial information which is utilised not only at the local level but increasingly at other levels of government. To build the spatial data infrastructure (SDI) at a state and national level, the role of local governments and their motivation to participate in the sharing of spatial information must be better understood. Although institutional problems still present some of the greatest challenges in building multi-jurisdictional SDIs, the technical and physical capacity of the smaller jurisdictions can impact on their ability to participate with larger and usually better resourced jurisdictions.In recent years partnerships have emerged as a useful mechanism for establishing a framework and environment conducive to data sharing. However, unless the partnership arrangements are carefully designed and managed to meet the business objectives of each partner, then it is unlikely that they will be sustainable in the longer term. This paper outlines research being conducted on the factors that contribute to the success of local-state government partnerships initiatives in Australia. The research methodology, which consists of mixed method approach utilising case studies and a qualitative survey of local government experiences in partnerships arrangements will be discussed. The case studies based in Queensland, Victoria and Tasmania focus on the arrangements to share property related information and reflect a variety of collaborative approaches. Some initial findings of the research will be presented and their possible implication to future partnership initiatives will be discussed.

    Facilitating disaster management using SDI
    Mansourian, A. ; Rajabifard, A. ; Valadan Zoej, M. J. ; Williamson, I. ( 2004)
    The role of spatial data and related technologies in disaster management has been well-known worldwide. One of the challenges concerned with such a role is access to and usage of reliable, accurate and up-to-date spatial data for disaster management. This is a very important aspect to disaster response as timely, up-to-date and accurate spatial data describing the current situation is paramount to successfully responding to an emergency. This includes information about available resources, access to roads and damaged areas, required resources, and required disaster response operations that should be available and accessible for use in a short period of time. Sharing this information between involved parties in disaster management is a challenge to facilitate coordinated disaster response operations. This paper aims to address the role of Spatial Data Infrastructures (SDI) as a framework for facilitating disaster management. It is argued that the design and implementation of an SDI model as a framework and consideration of SDI development factors and issues can assist disaster management agencies to improve the quality of their decision-making and increase efficiency and effectiveness in all levels of disaster management activities. The paper is based on an ongoing research project on the development of an SDI conceptual model for disaster management in Iran. This includes the development of a prototype web-based system which can facilitate sharing, access and use of data in disaster management and particularly disaster response.

    Land administration and Spatial Data Infrastructures
    Williamson, I. P. ; Grant, D. ; Rajabifard, A. ( 2005)
    Internationally the spatial data infrastructure (SDI) concept has focussed on national SDIs.However SDIs are increasingly focussing on large scale people relevant data (land parcelbased data or build environmental data) with the result that today it is suggested most SDIactivity worldwide is at this level. A central aspect in understanding these developments isthe evolution of mapping, and the growth of land administration systems and nationalmapping initiatives in different countries.The objective of this paper is to discuss the evolving nature of SDIs away from a simplenational concept to a complex hierarchy where large scale SDIs are the major influence. Thepaper concludes with a discussion of policy development and the impact of institutionalarrangements in managing spatial information.

    Making the SDI concept relevant to Asia-Pacific countries: the PCGIAP experience
    HOLLAND, PETER ; WILLIAMSON, IAN ; RAJABIFARD, ABBAS ; Manning, John ( 2005)
    Development of regional spatial data infrastructures (SDI) is one of the distinctive features ofthe last decade. This is mainly due to the need for seamless consistent spatial data beyondnational boundaries to support decision-making at a multi-national level. The development ofthese regional initiatives began with the creation of regional SDI coordination groups such asthe Permanent Committee for GIS Infrastructure for Asia and the Pacific (PCGIAP), formedin 1995 under the auspices of the United Nations Regional Cartographic Conference for Asiaand the Pacific (UNRCC-AP).The aims of the PCGIAP are to maximise the economic, social and environmental benefits ofgeographic information in accordance with Agenda 21 by providing a forum for nations fromthe Asia and Pacific region (the largest region in the world) to:Share experiences and cooperate in the development of a regional SDI;Contribute to the development of the global SDI; and,Participate in any other form of activity such as education, training, and technologytransfer at different jurisdictional levels.Over the past ten years, the PCGIAP has confronted a number of issues associated withbuilding a regional SDI. The group has also assisted member nations in their national SDIinitiatives.This paper describes some of the experiences of the PCGIAP, in particular:The establishment of a new geodetic datum for the region;The benchmarking of cadastral systems;The conceptualization of a framework for marine zone administration in the future; and,The strategic issues confronting the PCGIAP at the start of its 2nd decade of operation.

    Development of a Virtual Australia Utilising an SDI Enabled Platform
    Rajabifard, A. ; Binns, A. ; Williamson, I. P. ( 2005)
    Spatial Data Infrastructure (SDI) which is an evolving concept and can be viewed as anenabling platform linking data producers, providers and value adders to data users. With thisin mind, many nations and jurisdictions are investing in developing such platforms andinfrastructures that enable their stakeholders to work together in a more mutual approach tocreate distributed virtual systems that support better decision-making. The success of thesesystems depend on collaboration between all parties and need to be designed to supportefficient access, retrieval and delivery of spatial information to where it is needed.Within Australia, through the Cooperative Research Centre for Spatial Information (CRC-SI),there is a vision to provide a single entry point to SI, modeling and visualization tools, makingspatial information available and useful to all - at any time and in any place. This requires theseamless integration of SDIs at different levels including state and national to form a virtualjurisdiction such as Virtual Australia, providing a foundation for identifying best practice andkey performance indicators of SDIs in terms of their policy, technology and institutionalframeworks.This paper will discuss how SDIs can be used as an enabling platform in the construction anddelivery of a Virtual Australia, based on the SDI hierarchy model where data flows withminimal impediments within and between state and federal/national levels. The benefits ofVirtual Australia will be more than just the representation of feature based structures of theworld, it will also include the administration and institutional aspects of such features,enabling both technical and institutional aspects to be incorporated into decision-making. Thisis an aspect of research identified as more challenging than complex technical issues.
