This paper proposes an affordance-based approach for classifying local landmarks used in route descriptions. With 6 identified affordances the role which a landmark can take in route descriptions is specified. Affordances are extracted from in-situ experiments with 27 test persons describing route choices along 5 test routes in inner city and peripheral urban environments as well as along a ski tour in a snowy mountain environment. The aim of classifying landmarks with affordances is twofold: (1) a domain independent affordance-based taxonomy allows for classifying landmarks in different domains and (2) focusing on affordances allows for defining domain-independent classification principles as a foundation for the composition of way-finding instructions. The classification scheme is considered as a major contribution on the pathway to semantically enhanced navigation systems, using primarily landmark instead of metric direction concepts.
