ItemAssessment of error in digital vector data using fractal geometry(Taylor & Francis, 2000)This paper presents a new method for assessment of error in digital vector geographic data, where the features represented can be modelled closely by fractal geometry. Using example hydrological data from Ordnance Survey of Great Britain maps at a range of scales, a resolution smaller than which the digital representation of the feature does not exhibit fractal characteristics can be calculated. It is proposed that this resolution reflects the minimum ground resolution of the map, which in turn can be related to the source map scale.

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.

ItemA formal approach to imperfection in geographic information(Elsevier, 2001)Traditional computational models of geographic phenomena offer no room for imperfection. Underlying this tradition is the simplifying assumption that reality is certain, crisp, unambiguous, independent of context, and capable of quantitative representation. This paper reports on initial work which explicitly recognises that most geographic information is intrinsically imperfect. Based on an ontology of imperfection the paper explores a formal model of imperfect geographic information using multi-valued logic. The development of Java software able to assist with a geodemographic retail site assessment application is used to illustrate the utility of a formal approach.

ItemThe cadastral survey requirements of developing countries in the Pacific region: with particular reference to Fiji(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.

ItemCadastral survey techniques in developing countries: with particular reference to Thailand( 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.

ItemCoordination of cadastral surveys in New South Wales( 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.

ItemThe development of the cadastral survey system in New South Wales( 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’.

ItemLessons from the Swedish land data bank system( 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.

ItemConsiderations is assessing the potential success of a cadastral or land information management project in developing countries: a case study of the Thailand Land Titling Project( 1990)The Thailand Land Titling Project is undoubtedly a successful project combining technical, institutional, management, legal, training and educational components. It is a joint project by the Royal Thai Government, the World Bank and the Australian International Development Assistance Bureau. It is primarily concerned with the issuing of land titles to all freehold parcels in the Kingdom of Thailand, in addition to undertaking land administration reform, establishing a national valuation system, carrying out urban cadastral mapping for all urban areas in the country and developing a national land information strategy. The paper briefly overviews the project, outlines some of the lessons from the project and the significant socio-economic benefits of the project. However the paper concentrates on attempting to evaluate the reasons for the success of the project. In particular it argues that the institutional, economic, social, legal and political environment at the time of project preparation and implementation was conducive to its success. Such an evaluation is necessary to place the lessons, achievements and benefits of the Land Titling Project in perspective for others who may wish to translate these experiences to their own countries or jurisdictions. By drawing on the experiences of the Land Titling Project and other projects with which the author has been involved, an attempt is made to generalize the considerations and necessary environment for success of similar projects.

ItemLand information management at the World Bank( 1991-03)The surveying, mapping and land information management industry in both the government and private sectors in Australia has increasingly promoted the export of its expertise to developing countries during the 1980s, particularly in the land administration area. This activity has brought the industry in closer contact with organizations such as the World Bank with a view to increasing Australia’s share of the international consulting market. As a consequence of these developments and the extensive expertise in land management within the World Bank, in both the operational and research areas, the author spent six months undertaking research in land information management in developing countries in the World Bank during the latter half of 1989. This paper summarizes his impressions and experiences from this period but in particular highlights the role and importance of surveying, mapping and land information management as perceived by the World Bank. A major conclusion of the paper is that the surveying profession together with its institutions, systems and technologies is ‘alive and well’ and has a very sound and important future in the developing world.
