files and possibly some accompanying image files that are used as textures. Each text file can represent a part of the dataset, such as a specific region, a specific type of object (such as a set of roads), or a predefined LoD. The structure of a CityGML file is a hierarchy that ultimately reaches

43:(LoDs) for the 3D objects, which allows the representation of objects for different applications and purposes, such as simulations, urban data mining, facility management, and thematic inquiries.

The OGC Members adopted version 1.0.0 of CityGML as an official OGC Standard in August 2008. In late 2011, the OGC Members approved version CityGML 2.0.0. CityGML 3.0

In its most common implementation, which is the one generally used to disseminate and exchange data, CityGML datasets consist of a set of

down to individual objects and their attributes. These objects have a geometry that is described using GML.

Another important implementation of CityGML is the one of 3D City DB, which stores CityGML in a database.
