[DM2-8] Introduction to CityGML

3D Models, especially 3D city models are becoming more and more important. CityGML is the most important standard within the GI domain to describe City models semantically and geometrically. Relevant issues: - Motivation, Usage of CityGML - Relation to GML - Coherence of semantics and geometry - Principles of modeling - Level of detail concept - CityGML vs KML - Examples
