ItemSegmentation of Visually Similar Textures by Convolution FilteringBenke, 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.
ItemCadastral 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.
ItemTrends in land information system administration in AustraliaWilliamson, 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.
ItemLessons from the Swedish land data bank systemWilliamson, 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.
