    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.

    Cadastral futures: building a new vision for the nature and role of cadastres
    Bennet, Rohan ; Rjabifard, Abbas ; Kalantari, Mohsen ; WALLACE, JUDE ; WILLIAMSON, IAN (FIG Congress 2010, 2010)
    Over the last thirty years spatial information technologies and sustainability theory drove the creation of new visions, models and roles for the cadastre. Concepts including multi purpose cadastres, Cadastre 2014, and sustainable land administration radically altered understandings of the cadastre and its potential. Many of these concepts continue to be relevant in the contemporary context; however, like all disciplines, cadastral science must continue to look to the future to remain relevant. This paper begins this process and aims to provide preliminary insights into the characteristics and potential role of future cadastres. A qualitative research design based upon an exploratory case study underpins the research. Factors including globalisation, population urbanization, good governance, climate-change response, environmental management, 3D visualization/analysis technologies, wireless sensor networks, standardization, and interoperability are found to be driving developments in the cadastral domain. Consequently, six design elements of future cadastre emerge: Survey-Accurate Cadastres, Object-Oriented Cadastres, 3D/4D Cadastres, Real-Time Cadastres, Global Cadastres, and Organic Cadastres. Together, these elements provide a preliminary vision for the role and nature of future cadastres: the elements can be seen as likely characteristics of future cadastres. Collaborative research, potentially through the FIG framework, would enable further development of these design elements and would assist in defining the nature and role of future cadastral systems.
