Description: Das Projekt "Gendem: Map generalization for thematic and on-demand mapping in GIS" wird/wurde gefördert durch: Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung. Es wird/wurde ausgeführt durch: Universität Zürich, Geographisches Institut.In light of the present trend in cartography and GIS towards on-demand dynamic map creation, the research will concentrate on the development and study of generalization methods that are suitable for the rapid creation of maps and visualiza-tions. In response to two major streams in GIS-related mapping less than the creation of thematic maps and visualizations from GIS databases and the generation of on-the-fly maps in a distributed (Internet) computing context we intend to pursue the research in two subprojects. Integration of Generalization Methods for Thematic Mapping in GIS: The proposed research will extend our previous work on raster-based and vector-based measures for cartographic conflict detection and the generalization of categorical maps. It will further address the integration of categorical data with other feature classes (e.g., transportation, hydrology, point features) in the generalization process in order to obtain multitheme generalized maps. Progressive Vector Data Transmission and Dynamic Map Creation: This subproject will address web-based mapping, focusing on two major aspects. First, techniques will be developed for progressive transmission of linear and polygonal vector data, including experimental evaluation of the technical and cartographic quality of different schemes. Second, a comprehensive methodology for dynamic map creation will be developed and implemented.
