From experience, geometric representations of city objects and their semantic figures encoded in virtual city models are present in various qualities. Sometimes, repairing your virtual city model may be required to make it usable for urban analysis.
We are using automatic algorithms to control and repair the geometrical quality of 3D City Models.
Additionally, our data preprocessing algorithms control the model semantics, import external databases relevant for the urban analysis and enrich the city model. Goal is to maximise the reliability and precision of the urban analysis results.
