    Spatially Enabling Government – an International Challenge
    Williamson, I. P. ; Rajabifard, A. ; Wallace, J. ( 2007)
    The popular use of spatial technologies involves showing images and tracking assets and inventory in an increasing array of instruments, the most common being the ubiquitous mobile phone. These technologies penetrate into even low income poor countries, but their take-up and development concentrates in highly developed countries. This high-end use of these technologies will determine their future. Remarkable as these popular applications are, spatial technologies can also be used in even more dynamic, transformational ways. Transformational use of spatial technologies occurs when they are used to improve business processes of government, and assist delivery of policies for equitable taxation, conservation of natural resources and planning for rational growth. Use of this transformational capacity of spatial technologies in government creates a spatially enabled government (SEG). The major impediment to take-up of spatial information is counter-intuitive. We all use the new technology in our daily lives, but our capacity to understand the power of spatial information is remarkably small. In fact only about 1% of people in any society really understand spatial information with about 5% of people knowing something about the special technology. For 95% of people, spatial information and its supporting technologies is a mystery. Teaching people about spatial information and its technologies is therefore the first task in painting a vision of what is possible. The attractions of spatial technologies lie in how they present information, whether users rely on computers and the Internet, or on communications technologies. The adage of a “picture tells a thousand words” is now out of date. New digital pictures tell many stories, and, if the enabling platform is built, the pictures will become management tools of government. Spatial technologies are moving quickly. In Australia, since October 2006, Google Maps and Google Earth, combined with a geocoded national address

    Spatially enabling governments through SDI implementation
    Masser, I ; Rajabifard, A ; Williamson, I (TAYLOR & FRANCIS LTD, 2008)
    Spatially enabled government requires the development of effective SDIs that will support the vast majority of society, who are not spatially aware, in a transparent manner. This paper addresses three strategic challenges arising out of the need of creating this new environment. The first of these is the challenge for more inclusive models of governance given that SDI formulation and implementation involve a very large number of stakeholders from all levels of government as well as the private sector and academia. The second concerns the promotion of data sharing between different kinds of organisation. In some cases this may require new forms of organisation to carry out these tasks. The third challenge relates to the establishment of enabling platforms to facilitate access to spatial data and the delivery of data related services.

    Development of an interoperable tool to facilitate spatial data integration in the context of SDI
    MOHAMMADI, HOSSEIN ; RAJABIFARD, ABBAS ; Williamson, Ian P. (Taylor & Francis, 2010)
    The integration of multisource heterogeneous spatial data is one of the major challenges for many spatial data users. To facilitate multisource spatial data integration, many initiatives including federated databases, feature manipulation engines (FMEs), ontology-driven data integration and spatial mediators have been proposed. The major aim of these initiatives is to harmonize data sets and establish interoperability between different data sources. On the contrary, spatial data integration and interoperability is not a pure technical exercise, and there are other nontechnical issues including institutional, policy, legal and social issues involved. Spatial Data Infrastructure (SDI) framework aims to better address the technical and nontechnical issues and facilitate data integration. The SDIs aim to provide a holistic platform for users to interact with spatial data through technical and nontechnical tools. This article aims to discuss the complexity of the challenges associated with data integration and propose a tool that facilitates data harmonization through the assessment of multisource spatial data sets against many measures. The measures represent harmonization criteria and are defined based on the requirement of the respective jurisdiction. Information on technical and nontechnical characteristics of spatial data sets is extracted to form metadata and actual data. Then the tool evaluates the characteristics against measures and identifies the items of inconsistency. The tool also proposes available manipulation tools or guidelines to overcome inconsistencies among data sets. The tool can assist practitioners and organizations to avoid the time-consuming and costly process of validating data sets for effective data integration.

    Exploring the key areas of spatial metadata automation research in Australia
    OLFAT, HAMED ; Kalantari, Mohsen ; RAJABIFARD, ABBAS ; Williamson, Ian P. ; Pettit, Christopher ; Williams, Stephen (Leuven University Press, 2010)
    Improving the spatial metadata management process to facilitate data discovery, access and retrieval through an SDI platform has been the goal of a number of organizations at different jurisdictional levels in Australia. A current linkage research project titled “Spatial Metadata Automation” is being conducted at the University of Melbourne in conjunction with some industry partners. This research project aims to explore different approaches for automating spatial metadata so that the process of creating and updating spatial metadata – where feasible – becomes automatic. As part of the project an online questionnaire was designed and distributed within the major organizations dealing with spatial data in Australia to assess the users’ needs regarding metadata automation and also the current status of the activities in metadata creation and updating. This paper presents the results of the assessment process and explores the key areas of spatial metadata automation research in Australia. It also reviews some of the more important initiatives regarding spatial metadata in this country and explains the characteristics and framework of the current research. The paper then discusses the structure of the questionnaire and the results of the responses analysis. Finally, the findings, future needs and research questions are presented.
