A Framework For The Generalization Of 30 City Models

Authors : Guercke Richard . Brenner Claus .

Abstract

With a growing availability of detailed 3D city models an increased demand for the generalization of these models is going to arise. In order to build a useful system for the generalization of highly detailed 3D city models. it is necessary to give the user the opportunity to define the relevance of features on a semantic basis. This requires a high leve! of semamic information that is often not present in existing models and extremely flexible generalization strategies that allow different algorithms with different parameters to be used for the sarne rnodel. ln order to meet these requirements. we propose a framework for the generalization of 3D city models that supports the definition of custom feature hierarchies and generalization algorithms and offers predefined default features and generalization modules that can be used where the application allows it.
