ItemGroundhog day, ..., again! [Review of the book Geographic information science: mastering the legal issues]( 2006)The disappointed reviewer concludes that this text is no better than the previous text by the author (also reviewed by the reviewer seven years ago in the Law Institute Journal). This latter book is much less expensive than the earlier one that carried a RRP of $215...Reviewer.

ItemSpatial data quality capture through inductive learning(Springer Verlag (Germany), 2000)The relatively weak uptake of spatial error handling capabilities by commercial GIS companies and users can in part be attributed to the relatively low availability and high costs of spatial data quality information. Based on the well established artificial intelligence technique of induction, this paper charts the development of an automated quality capture tool. By learning from example, the tool makes very efficient use of scarce spatial data quality information, so helping to minimise the cost and maximise availability of data quality. The example application of the tool to a telecommunications legacy data capture project indicates the practicality and potential value of the approach.

ItemTeaching and research programs in land and geographic information systems at the University of Melbourne, Australia( 1990)As in many other parts of the world, Australia is experiencing a severe shortage of Land and Geographic Information System (LIS/GIS) specialists who possess appropriate tertiary education backgrounds. This shortage of qualified personnel is causing difficulties for public agencies trying to establish LIS/GIS which, having fought for approval of staff increases, are often in the embarrassing position of not being able to fill positions when finally allowed to do so. This shortage applies just as equally to the private and academic sectors.In an effort to address this imbalance, The University of Melbourne has designed new LIS/GIS courses and subjects, at both the undergraduate and postgraduate levels, with the aim of catering for young professionals about to enter the LIS/GIS community, and current administrators, academics and practitioners who find they now need a stronger background in the science, technology and management issues surrounding LIS/GIS.The paper outlines a multi-disciplinary strategy at The University of Melbourne for teaching and research in LIS/GIS. The paper, however, concentrates on the programs within the Department of Surveying and Land Information (A Centre of Excellence in Land Information Studies designated by the Institute of Land Information based in Washington, DC), and a new Graduate Diploma in Geographic Information Systems being introduced jointly by the above department and the School of Environmental Planning within the University.

ItemThe need for improved forms of conceptual models in Geographical Information System development( 1991)While numerous books have been published in the past two decades on the subject of information system development methodologies, it is now recognized that these techniques need modification to suit the peculiar nature of Geographical Information Systems (GIS). However, regardless of how system development life-cycles might be varied to suit GIS, the use of models remains a common feature of the development of any information system. It is argued that high-level conceptual models, as used in the initial system evaluation phase, are perhaps the most important type of model in terms of providing an overall picture of what the system is designed to achieve -- yet they remain the least understood. The aim of this paper is to provide a greater understanding of their role and purpose and to highlight their importance in effective GIS development and implementation. Suggestions are also made for improving the form and content of conceptual models so that their meaning becomes clearer

ItemImplementing LIS/GIS from a customary land tenure perspective: the Fiji experience( 1995)This paper briefly reviews Fiji's national land information system (LIS) strategy and the major land and geographic information systems (LIS/GIS) initiatives that have been under way in the major government organisations in Fiji up to April 1994. It also describes and attempts to examine the impact that these initiatives have had on the people who continue to live under Fiji's customary land tenure systems.

ItemThe dynamic nature of spatial data infrastructures: a method of descriptive classification( 2001)Spatial Data Infrastructure (SDI) is understood and described differently by stakeholders from different disciplines and different administrative/political levels. However, current SD Idefinitions are individually insufficient to describe the dynamic and multi-dimensional nature of SDI. Despite the international interest and activities toward SDI development, SDI remains very much an innovation even among practitioners. There are still doubts regarding the nature and identities of SDI, particularly in connection with how it evolves over time to meet user needs. Asa starting point a means to describe SDI’s multi-dimensional capacity as an inter- and intra- jurisdictional spatial information framework is required. The aim of this paper is to better understand and describe the nature of SDI and its components. A method to classify the perceived roles of SDI is identified. The method is extrapolated from a technique to describe different perspectives of Geographical Information System (GIS) diffusion, based on identified parallels between GIS and SDIs. The methodology may facilitate description and understanding of the SDI technological and user environment, by promoting insight into the dynamic roles of SDI.

ItemFuture directions for Spatial Information Management in Australia-a land administration perspective( 1999)Future directions for spatial information management in Australia, from a land administrationperspective, are discussed. Sustainable development, micro-economic reform, globalisation andtechnology are highlighted as the drivers for change. The changing spatial information environment withemphasis on land administration and cadastral issues is examined by drawing on research beingundertaken at the University of Melbourne. Issues concerned with future land administrationinfrastructures such as the changing humankind to land relationship, cadastral reform and native title arehighlighted. Specific cadastral and land administration issues and technologies which impact on spatialinformation strategies are reviewed, including understanding the business-infrastructure relationship inspatial information management, modelling the maintenance of cadastral systems, the changing nature ofspatial data infrastructures, the spatial hierarchy problem, the importance of developing partnerships andthe impact of communications and WWW technologies. The paper concludes by emphasising that anygovernment spatial information strategy is intimately linked to land administration and is influenced byglobal drivers such as sustainable development, micro-economic reform and globalisation, as well astechnology. Understanding the inter-dependence between these global drivers is a key to successfulspatial information management strategies.

ItemLand administration, spatial systems and citiesan Australian perspective( 1999)The paper argues that any spatial information strategy for urban, local government orcity jurisdiction is intimately linked to and influenced by the state or national landadministration and cadastral systems where it is located. It is these state or nationalsystems which usually provide the spatial infrastructure for urban information systems.Therefore to understand current trends in urban information systems, changes and trendsin state and national land administration systems must also be understood. The paperaddresses this topic by exploring the changing humankind-land relationship and theglobal drivers of sustainable development, micro-economic reform, globalisation andtechnology, with emphasis on Australian state spatial information systems. It draws onresearch being undertaken at the University of Melbourne to highlight some of thetrends and issues
