Abstract Semantic 3D city modeling and building information (BIM) are methods for modeling, creating, analyzing three-dimensional representations of physical objects the environment. Digital built environment has been approached from at least four different domains: computer graphics gaming, planning construction, urban simulation, geomatics. This chapter introduces similarities differences mod...

A multitude of new applications is quickly emerging in the field of Building Information Models (BIM). BIM models describe buildings with respect to their spatial and especially semantic and thematic characteristics. Since BIM models are manually created during the planning and construction phase, they are only available for newly planned or recently constructed buildings. In order to apply the...

Abstract. The combination between dense point clouds and 3D vector objects permits new cartographic representation of urban information. This paper proposes an extension for the CityJSON encoding to support clouds. Following 3.0 CityGML specifications, attributes features are added core module v1.0.1 CityJSON. Two solutions proposed: inline complex geometries external link a remote file. extend...
