The City Geography Markup Language ( CityGML ) is a GML application scheme for storing and exchanging virtual 3D city models. CityGML has been an OGC standard since August 13, 2008 .
Urban and landscape objects are modeled, in particular the terrain, buildings, water and traffic areas, vegetation, street furniture and land use. Each object can appear in different levels of detail . In addition to the geometry and appearance, the semantics (meaning, subject matter) and topology (relationships, neighborhoods) of the objects are also described. CityGML is based on standards from, for example, the Open Geospatial Consortium (OGC) and the ISO standard series 191xx.
CityGML has been developed since 2002 by the Special Interest Group 3D (SIG 3D) in the geodata initiative North Rhine-Westphalia (GDI NRW) and now within the framework of the geodata infrastructure Germany (GDI-DE). The members of the group come from business, administration and research from all over Germany, Austria, Switzerland and Great Britain.
Since 2013 the OGC CityGML Standards Working Group (SWG) and the Special Interest Group 3D (SIG 3D) have been working on the implementation of CityGML 3.0, which should be completed by the end of 2018.
