    Segmentation of Visually Similar Textures by Convolution Filtering
    Benke, K ; SKINNER, DR (Australian Computer Society, 1987-08-01)
    We describe an approach to texture segmentation designed for the extraction of a textured object from a textured background. The approach assumesthatno information is available on the objecttexture butthat a prior analysis ofthe background texture has been undertaken. The power ofthe approach is demonstrated on a texture composite for which object extraction and identification is almost impossible by visual inspection.

    The cadastral survey requirements of developing countries in the Pacific region: with particular reference to Fiji
    Williamson, Ian P. (Commonwealth Association of Surveying and Land Economy (CASLE), 1982)
    The cadastral survey systems introduced into many developing Pacific countries during colonial eras often do not meet the social and economic demands placed on them at the present time. Such systems can seriously limit the availability and transfer of land hence restricting the development and economic advancement of a country .This paper considers the subject generally although particular reference is made to the system presently operating in Fiji.

    Cadastral survey techniques in developing countries: with particular reference to Thailand
    Williamson, Ian P. ( 1983-09)
    The benefits of an efficient cadastral, survey and land registration system to developing countries are described. The legal, and particularly the technical procedures in creating a cadastre are discussed. The use of ground and photogrammetric survey techniques are highlighted. The reasons for restricting, the introduction of efficient cadastral survey systems are considered. Thailand is used as an example of a country which has, shown much flexibility in improving its cadastral system to better meet the needs of its developing economy. In this regard, the institutional and legal arrangements in the Thai cadastral system are described, as is the development of the cadastral survey system. As an indication of continuing flexibility, the future direction of 1he Thai cadastral, system is discussed.

    Coordination of cadastral surveys in New South Wales
    Williamson, Ian P. ( 1984-12)
    A review is made of all major attempts and recommendations to introduce coordination of cadastral surveys into New South Wales. The review covers the period from the first directives by the Government for a general survey in the 1820s, to the proposals to introduce coordination based on the Integrated Survey Grid in the 1970s. An attempt is made to draw some conclusions from the historical review which will assist in the introduction of some form of coordination of cadastral surveys in the future.

    The development of the cadastral survey system in New South Wales
    Williamson, Ian P. ( 1984-03)
    This article reviews the development of the cadastral survey system in N.S.W. Particular emphasis is given to an understanding of why the system developed based on isolated survey principles. In reviewing the development, three critical periods have been considered: early survey administration, ‘1788- 1831; the formative years, 183l-1864; and refinement, 1864-present’.

    Cadastral and land information systems: where are we heading?
    Williamson, Ian P. ( 1986)
    The land information system concept is reviewed with particular emphasis on the historical development of the central cadastral (parcel) data base. The role of cadastral surveying, cadastral mapping and the development of digital cadastral data bases is discussed. Future directions for parcel based land information systems are suggested, with a conceptual model for an integrated digital cadastral data base being highlighted. The changing roles of the surveying and mapping community, and the needs for education in the area, are highlighted.

    Trends in land information system administration in Australia
    Williamson, Ian P. ( 1986)
    Current land information system (LIS) activities and trends, at the Commonwealth, state and local government levels in Australia, are briefly reviewed. The reasons for the pre-occupation with parcel (cadastral) data are discussed while recognising that the challenge for the next decade is the integration of resource, environmental and socio-economic data into parcel-based systems. LIS models are reviewed with particular emphasis on LIS administration in the Australian context.

    Lessons from the Swedish land data bank system
    Williamson, Ian P. ( 1987-12)
    In 1985 the Victorian Government contracted consultants from the Swedish Central Board for Real Estate Data to assist in a study into the development of the Victorian land information system (LIS) with emphasis on the development and role of an automated land titles system within the LIS. This paper suggests it is beneficial for Victoria to have a broad understanding of the Swedish system in order to put any recommendations in perspective. As a consequence the paper reviews the Swedish cadastral and land information system, and highlights lessons and issues derived from the Swedish system which may benefit the development of land information systems in Victoria as well as other jurisdictions in Australia.
