Module: 3D GIS, City Models and Digital Twins

Lecture: 3D GIS data standards

Lecture summary

The last lecture of this block describes the 3D city models on data level. It introduces the student
into the CityGML conceptual model and describes its modules and how they can be used in diverse
aspects of city modelling. It goes more deeply into certain representation, e.g. geometric, topologic
or time, because knowledge of these is important for understanding the process of BIM-GIS
integration. Further, the lecture provides information on different CityGML encodings as well as
other 3D formats.

Learning outcomes

At the end of this lecture, the learner is expected to be able to:

Name several ways how the 3D data can be stored, with focus CityGML encodings
Summarize the main parts of CityGML Conceptual model and how they can be used
Understand the aspects of CityGML that are important for conversion to and from BIM
