Managing Versions and History Within Semantic 3D City Models for the Next Generation of CityGML

Abstract: Semantic 3D city models describe city entities by objects with thematic and spatial attributes and their interrelationships. Today, more and more cities worldwide are representing their 3D city models according to the CityGML standard issued by the Open Geospatial Consortium (OGC). Various application areas of 3D city models such as urban planning or architecture require that authorities or stakeholders manage parallel alternative versions of city models and their evolution over time, which is currently not su… Show more

“…In addition, more thorough tests are required to evaluate application outputs against all different types of geometrical deviations. Finally, the methods and algorithms proposed in this research can be extended and applied to enable a version control system for collaborative work in modelling and storing digital 3D city models in the future (Chaturvedi et al, 2015).…”

“…This way, older datasets can both be updated and still retain their respective core structure, including own rules of syntax and internal object references. This plays a key role in enabling a version control system for collaborative work in modelling and storing digital 3D city models (Chaturvedi et al, 2015). Moreover, the number of transactions required for a WFS-enabled database is also reduced significantly.…”

“…Nevertheless, the CityGML standard currently does not provide us with a way to store this kind of information, because only the current state values are included (Morel and Gesquière 2014). An alternative is to extend CityGML to allow for versions of the entire model, or of some specific city elements, to represent different planning alternatives (Chaturvedi et al 2015). There is also a modeling approach and an implementation for supporting the management of versions and history within CityGML (Chaturvedi et al 2015).…”

Another related problem is to keep the changes under control as the models evolve.…”

“…Furthermore, a unified model removes the need to duplicate the data (base model and visualisation model). With datasets covering larger and larger areas, exceeding the city scale, as well as existing in multiple temporal versions (Chaturvedi et al, 2015a), storage may well become an issue in the future.…”
