Kolloquium Geoinformatik Algorithms for focus-and-context maps

A focus-and-context map provides a user with detailed information about an area of interest while displaying context for orientation. In my talk I present algorithmic approaches to the automatic generation of focus-and-context maps from large-scale geospatial data. This includes an optimization-based distortion technique to enlarge a user-selected region in a map as well as algorithms for map generalization and map labeling that target navigation applications.
