3D Building Modeling and Indoor Fire Event Representation in CityGML
3-dimensional (3D) city model is increasingly popular in urban planning and disaster management. City Geographic Markup Language (CityGML) is an open data model and XML-based format for the representation and exchange of virtual 3D city model. This paper analyzed the modeling mechanism of 3D CityGML building model in LOD4 (Level of Detail) and proposed a method representing a fire event in CityGML. Our method included three operations：1) editing of building’s hierarchy and attributes information; 2) representing of semantic information of buildings surfaces, roof height and interior furniture; 3) representing of fire event by a vivid icon. With our method, 3D building model and indoor fire event can be both represented in CityGML, which is important to analyses urban emergency events.
