CityGML stands for City Geography Markup Language, which is an XML-based format developed by Open Geospatial Consortium (OGC) representing urban features like buildings, vegetation, transportation, and infrastructure in 3D models. It provides a standard model for describing 3D objects with respect to their geometry, topology, semantics, and appearances.
Level of Details (LOD) in CityGML:
- LOD0: Basic Level, which represents the terrain.
- LOD1: Extruded block models
- LOD2: Coarse prismatic model with multiple semantic classes (roof, wall)
- LOD3: Architecturally detailed model with windows and doors.
- LOD4: Detail models with interior details like walls, floors, and furniture.
CityGML can be applied in Infrastructure and facility management, smart city application, urban planning and simulation, and many more.
