dc.description.abstract-translatedWe present the concept of the FOCUS LINE, a new geometric distortion method designed to solve the problem of symbol cluttering in maps. FOCUS LINE´s utilise significant differences in the symbol density across the original map and distorts the layout to create the presentation area required. When focussed on dense areas, the distortion guarantees a continuous and smooth integraion of the enlarged area in the map as a whole. Unlike related approaches, the FOCUS LINE distortion considers the properties of the street network as found in city maps. The Focus line polyfocal distortion is characterised by a new shape of distortion reducing unnecessary distortions to the overall layout. The distortion is designed such that the amount is easily adjustable by parameters that have a geometric correspondence. Applying this method to tactile route maps, we discuss the results of an automatic approach and present interactive tools based on the FOCUS LINE distortion. These tools have been included in a prototypical implementation of a map editor for a systematical modification of the map layout.en
