Mapping the CityGML Energy ADE to CityGML 3.0 Using a Model-Driven Approach

ISPRS International Journal of Geo-Information
With the increasing adoption of semantic 3D city models, the relevance of applications in the field of Urban Building Energy Modelling (UBEM) has rapidly grown, as the building sector accounts for a large part of the total energy consumption. UBEM allows

MODELING AN APPLICATION DOMAIN EXTENSION OF CITYGML IN UML [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
This paper presents key aspects of the development of a Dutch 3D standard IMGeo as a CityGML ADE. The new ADE is modeled using UML class diagrams. However the OGC CityGML specification does not provide clear rules on modeling an ADE in UML.

Modeling Cities and Landscapes in 3D with CityGML

, 2018
CityGML is the most important international standard used to model cities and landscapes in 3D with extensive semantics. Compared to BIM standards such as IFC, CityGML models are usually less detailed but they cover a much greater spatial extent. They are also available in any of five standardized levels of detail.

AUTOMATIC CONVERSION OF CITYGML TO IFC [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Abstract. The trend of increased usage of both BIM and 3D GIS and the similarity between the two has led to an increase in the overlap between them. A key application of such overlap is providing geospatial context data for BIM models through importing 3D GIS-data to BIM software to help in different design-related issues.
