CityDoctor2 is a quality check software for 3D city models in CityGML format. CityDoctor can read CityGML 1/2 documents and since version 3.12 can also read CityGML 3 with restrictions. All check results can be output in xml or pdf form. Additionally CityDoctor implements the [QualityADE](https://transfer.hft-stuttgart.de/gitlab/citydoctor/qualityade) to save test results directly into CityGML.
