The Open Geospatial Consortium ( OGC ) has published the final report of the CityGML Quality Interoperability Experiment as an Engineering Report.
In the experiment methods have been developed and evaluated for quality management of 3D city models. The focus was on the development and definition of test criteria for geometry, semantics and conformance requirements for the CityGML building model.
SIG3D was one of the initiators of the CityGML Quality Interoperability Experiment and has introduced the SIG3D Modeling Guide into the project and was responsible for the formalised definition of conformance requirements.
The Engineering Report is available at portal.opengeospatial.org/files/?artifact_id=68821,
