Two serious problems that often arise in map generalization are “what should be aggregated” and “when to aggregate”. This very much depends on the knowledge of the theme to be mapped. In the case of vegetation mapping at different scales, some inherent rules on vegetation, such as their biological characteristics and spatial distribution, must be incorporated in addition to existing generalisation algorithms, so that automated generalisation can be achieved. This paper describes the development of such rules based on bio-geographical principles for the implementation of existing generalisation operators and, in particular, the integration of these operators.

The south-western trans Iranian railway line connecting Tehran, Iran to Khoramshahr in the southwest crosses the great Zagros range. One of the localities on this line is the Shahbazan railway station. Shahbazan station is located in the Alwar section of the central Zagros belt in the southwest of Iran. Complex geological-geomorphological activities have created an immature and rugged landscape which in turn imposes various natural hazards (landslide, erosion and flash flooding) to both people and the railway infra-strucutre. In order to address these problems on a regional scale, a digital elevation model (DEM) was used in conjunction with selected field visits during which various parameters related to lithology (dip, strike and rock types), structures (joints, fracturres, faults and folds), soil types, landuse and land cover were obsereved and measured. For the creation of a DEM, a digital topographic map prepared by the Iranian Surveying Organization was used. The DEM was computed using x, y, z attributes in text format. The methodology includes an interactive visual calibration that adjusts parameters while referring to observed landslides. Based on field data collected, the DEM was calibrated to generate stability zone map and saturation zone map of the study area which address to natural hazards like landslide. The analyses of drainage morphometery, relief and saturation maps reveals zones of stability-instability and saturation within the study area which are in harmony with landslide and rock fall zones. However, the study also indicates that the DEM provides a useful tool for rapid evaluation of natural hazards and mapping of large areas with less time and good results.

To determine the effect of cartographic visualisation of tourist maps on their users, a survey was conducted among geography students. One of the aims of the study was to analyse the effect of a particular type of visualisation of a tourist map on decisions made by its users (e.g. a change in his/her tourist preferences). The analysis of the questionnaire suggests that the type of cartographic content has a profound effect on the choice of potential tourist attractions and planning tourist routes.

“Thomas Baines and the ‘Great Map’”, a CD-ROM published by Campbell Collections, University of Natal in 2001, is the result of a joint project comprising South African and Australian scholars working on Thomas Baines's “Map of the Gold Fields of South Eastern Africa (1872)”. Baines, the well known artist and explorer who died in Durban, South Africa, in 1875, made two trips to modern day Zimbabwe in search of gold bearing sites for the Natal Land and Colonisation Company. One of the large maps which he drew on this trip is the subject of study for this interdisciplinary team coordinated by Lindy Stiebel (Professor of English Studies, University of Durban-Westville). The other team members are Jane Carruthers (History, University of South Africa), Vivian Forbes (Chief Cartographer, University of Western Australia), Norman Etherington (Professor of History, University of Western Australia) and staff of the Campbell Collections, Durban, South Africa. The CD aims to make Baines's manuscript map of 1872, which is owned by the Campbell Collections, more accessible to scholars and the general public alike. The CD reproduces the map in digital form, plus accompanies the map with three essays that situate the map historically, cartographically and discursively. Four of Baines's paintings relevant to the Gold Fields expedition also appear on the CD. All legible place names on the map have been bookmarked for easy click-and- find access and the accompanying essays extensively hyperlinked. This paper discusses and assesses this pioneering project; plus points the way to other potential projects in which a similar ‘marriage’ of technology to the past can be implemented.

Whittles Publishing constantly strives to produce quality, practical books at a reasonable price and our authors are internationally known and respected. Digital Aerial Survey and Manual of Aerial Survey are two recently-published books from our geomatics stable and there are more planned, such as a second and enlarged edition of Maths for Map Makers; and the definitive handbook for digital imaging, The Digital Image. In case members are not familiar wi th our established geomatics books, these include Close Range Photogrammetry and Machine Vision by K.B. Atkinson; Datums and Map Projections for Remote Sensing, GIS and Surveying by Dr. J.C. Iliffe; Digital Imaging by Ron Graham, and Small Format Aerial Photography by Warner, Graham and Read. For a historical slant on cartography there is Everest-the Man and the Mountain by J.R. Smith and the forthcoming Journey into Africa: The Life and Death o f Keith Johnston, Scottish Cartographer and Explorer (1844-79) by James McCarthy. Further details of these are all available on our website, www.whittlespublishing.com which is updated monthly. We look forward very much to establishing links with the MSlA at this exciting time of change and development of the spatial science bodies. Whittles Publishing advertisement may be found at the front of this issue of CAROGRAPHY.

Australia has a new institution representing professionals in the spatial sciences and providing for their professional development the Spatial Sciences lnstitute (SSI). The establishment of the new body was announced in Canberra today and is the outcome of two years of discussion between the five major professional associations that previously covered the industry. The members of the Institution of Surveyors, Australia (ISA), the Institution of Engineering and Mining Surveyors, Australia (IEMSA), the Mapping Sciences Institute, Australia (MSIA), the Australasian Urban and Regional Information Systems Association (AURISA) and the Remote Sensing and Photogrammetry Association of Australasia (RSPAA) voted overwhelmingly to combine those institutions into one body. Interim Chairman o f the new Institute, Mr Graham Baker, said the existing institutions reflected the structure of the industry 20 years ago when the roles of surveyors, cartographers and photogrammetrists were quite distinct. But changing technology had blurred the boundaries between the professions. Young graduates frequently declined to join any of the institutions because none of them adequately addressed the field of activities in which they worked. "We believe that the SSI will be better structured to provide for the cross-disciplinary professional development needs of its members," said Mr Baker.
