Generalization and Visualization of Multiple Levels of Details (LoDs) of Buildings Modeled in CityGML

Abstract
In this paper, a framework for generalization and visualization of city models stored in CityServer3D is proposed. Initially, reconstruction of city models is carried out using Google SketchUp. Reconstructed building models are exported to XML-based CityGML. CityServer3D which is a client-server system to manage 2D and 3D city models is used to store, process and visualize 3D city models. Data about 3D buildings of Putrajaya city of Malaysia are acquired, modeled in CityGML and stored in CityServer3D to be used for generalization and visualization purposes.
