The symposium was organized locally by the University of Glamorgan (UK) and held in Cardiff (UK) in November 2007. It was the latest in a series of annual events that started in Kyoto 2001 and now alternate locations each year between East Asia and Europe. As in previous years, the aim of the symposium was to provide an up-to-date review of advances and recent developments in theoretical and technical issues relating to Web and wireless GIS technologies. The symposium organizers received 45 full papers in response to the call for papers. These papers went through a thorough review process, with each paper being assessed by at least three reviewers. The quality of papers was high, and 21 were selected for presentation and inclusion in these proceedings. It was particularly pleasing to note that 19 different countries are represented by the authors of selected papers. The keynote address was delivered by Jonathan Raper of City University, London, in which he talked about his research work in the areas of location-based services and mobile information needs. We wish to thank all the authors that submitted papers to this symposium. Our special thanks go to all those who attended, and particularly those who presented.

An algorithm is presented that performs operations of displacement, size exaggeration, deletion and size reduction of multiple map objects in order to resolve graphic conflict resulting from map scale reduction. It adopts a trial position approach in which each of n discrete polygonal objects is assigned k candidate trial positions that represent the original, displaced, size exaggerated, deleted and size reduced states of the object. This gives rise to a possible kn distinct map configurations; the expectation is that some of these configurations will contain reduced levels of graphic conflict. Finding the configuration with least conflict by means of an exhaustive search is, however, not practical for realistic values of n and k. We show that evaluation of a subset of the configurations, using simulated annealing, can result in effective resolution of graphic conflict.

Map generalization with a triangulated data structure / Christopher B. Jones in Cartography and geographic information systems, vol 22 n° 4 (December 1995)

An experimental map generalization system has been developed which addresses this issue by representing spatial objects within a simplicial data structure (SDS) based on constrained Delaunay triangulation of the source data. Geometric generalization operators that have been implemented include object exaggeration, collapse, amalgamation, boundary reduction and displacement. The generalization operators exploit a set of primitive SDS functions to determine topological and proximal relationships, measure map objects, apply transformations, and detect and resolve spatial conflicts. Proximal search functions are used for efficient analysis of the structure and dimensions of the intervening spaces between map objects. Because geometric generalization takes place within a fully triangulated representation of the map surface, the presence of overlap conflicts, resulting from individual operators, can be detected due to the introduction of singularities in the triangulation, the structure of which is used to generate displacement vectors to resolve the conflict. Examples of the application of the implemented operators are described and illustrated using large scale topographic map data.
