ItemToward e-land administration : Australian online land information services( 2005)Sustainable development (SD) is accepted as a central driver in countries world wide with land administration playing an important role in delivering SD objectives. Within this context the emerging use of the Internet and other information and communication technologies (ICT) are increasingly being utilised by land administration organizations. These technologies provide opportunities for better service delivery and customer satisfaction and a reduction in operating costs. However establishment of these systems as part of e-land administration and in the context of e-government has to date not been fully realised and is often problematic.E-land administration includes the coordination among various parts of land administration businesses including front office operations like online customer services and private partnership services, and also back office operations like internal work flow and central data base management. The first step in improving the current systems within a particular jurisdiction is assessing the current performance of online land information services as part of e-land administration.There are various initiatives to deliver land related information over the Internet for the public in the different Australian states. Analysing these experiences and determining good practice will assist in proposing effective and innovative solutions to improve or re-engineer the existing services as a key infrastructure for implementing e-land administration services.This paper first introduces and discusses various quality of service criteria for the assessment of an online land information system. The criteria include popularity, performance, functionality and user requirements of services. The paper then reviews and presents current land administration services in Australian states including a statistical analysis to better understand the advantages and deficiencies of current services. The results are assessed and suggestions are proposed for improving on

ItemSpatially enabled land administration: paradigm shift in land information management( 2013)The administration of land is challenged by the increasing need of clients for land information and by the creation of new land related commodities and interests. In this space, spatial information and technologies can change the way business and governments manage activities and solve problems in relation to land. Much information relates to place and locations. Some of this is spatial information, but a great deal is information that can be organised according to its impact on a place. These emerging spatial technologies potentially expand the capacity of societies. They provide possibilities for ordering information that are profoundly world changing. The more difficult task involves embedding new technologies into the most conservative and fundamental processes in land information and management of the land market, particularly, into the land registries. Regardless, the opportunities provided by emerging technologies are driving changes in the way governments interact with their citizens, principally in initiatives to spatially enable their processes, as well as their information .Building on the growing need for land information and availability of spatial technologies, this paper presents two paradigm shifts in collecting and managing land information in the context of spatially enabled land administration.

ItemLand and property information in 3D(International Federation of Surveyors (FIG), 2012)People increasingly live in high density urban, often high rise and multi functional buildings. These increasingly urbanized populations will predominantly live in multi-level, multipurpose, highly engineered, high-rise developments. Cities require significant infrastructure above and below the ground. Rapidly expanding vertical cities and their populations will experience a range of new environmental, social and economic challenges. The lack of an efficient and effective three dimensional solution limits the ability of the public to visualize and communicate 3D developments, the ability of architects, engineers and developers to capitalize on the full potential of 3D title models; the ability of governments and developers to visualize multi-level developments resulting in increased costs and delays; and the ability of land registries to administer a title registration system that can accommodate these increasingly complex multi-level developments. This paper aims to introduce an approach which helps address the problem of modelling and managing complex 3D property rights, restrictions and responsibilities (RRR). The outcomes of this research incorporate the third dimension of height into the land subdivision and development process to build an infrastructure for managing and modelling spatial extension of these complex property RRRs. This research moves the multiple two dimensional drawings that now identify buildings and infrastructure objects and their separate parcels into authentic visual 3D representation of the building and objects that meet the exacting legal standards of ground surveys.

ItemNational land information infrastructure through a collaborative framework(International Federation of Surveyors (FIG), 2012)Australia is being faced with issues which demand a national focus. These issues include natural resource management, land markets, trading in commodities such as water and carbon, and the development of national policies for housing and infrastructure. Businesses also are demanding a more national approach as an increasing number of businesses now operate nationally. This is reflected in the Australian Bureau of Statistics figures which show the number of businesses operating in all states and territories increased by 70% between 2003 and 2007. Over the past several years considerable effort has been directed by the Australian Government towards the development of a “seamless economy” to improve productivity across its federated system of government. In this environment, Land administration in Australia is also jurisdictionally based with no national infrastructure capable of delivering the land information necessary to meet Australia’s needs. In the past, this jurisdictional based approach to land administration has satisfactorily served Australia in an environment where the vast amount of service delivery by both business and government was state focused. Each jurisdiction has taken advantage of the ongoing technological developments to enhance their respective systems and it would appear that many of the needs at a jurisdictional level continue to be met. Whilst land administration has not featured specifically in this reform several of the nominated projects involved land in some form. To respond to the national drivers, this paper aims to introduce a collaborative framework for the implementation of a national land administration infrastructure which relies on the state and territory based systems as its primary source of information.

ItemExploring the key areas of spatial metadata automation research in Australia(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.

ItemNo Preview AvailableCadastral futures: building a new vision for the nature and role of cadastres(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.
