Lay Summary (English)

Lay summary
As its predecessor project DEGEN the research on DEGEN2 will be situated in the domain of automated map generalization. Map generalization (short: generalization) is a function of fun-da-mental importance in digital cartography and geographic information systems (GIS), needed for a variety of tasks such as the creation and maintenance of geospatial databases at mul-tiple scales, cartographic visualization at variable scales, and controlled data reduction. More precisely, the proposed project will continue to focus on data enrichment for map generalization. Spatial databases are typically designed to serve a variety of purposes and hence are not optimized to support complex cartographic processes such as map generalization. Data enrichment, therefore, is necessary to equip the ‘raw’ spatial data with additional information that is suited to support the complex decision making processes that prevail in automated map generalization, such as the detection of cartographic conflicts, the selection of appropriate generalization algorithms, the automated setting of algorithm parameters, and the ‘orchestration’ of interrelated generalization algorithms. Two PhD students are engaged in two subprojects that are linked by a common conceptual framework (the notion of so-called horizontal and vertical relations in order to describe the essential structures and patterns of a map) and they are using the same software platform as experimental workbench. The extension of DEGEN2 will allow the students to wrap up their research, exploit synergies between the subprojects, and complete their theses.
