Detecting Symmetries in Building Footprints by String Matching


This paper presents an algorithmic approach to the problem of finding symmetries in building footprints. The problem is motivated by map generalization tasks, for example, symmetry-preserving building simplification and symmetry-aware grouping and aggregation. Moreover, symmetries in building footprints may be used for landmark selection and building… (More)
