The OGC calls for participation in an interoperability experiment to define data quality requirements for virtual 3D city models encoded in CityGML.
CityGML has been widely adopted and is used throughout the world as a data model and exchange format for virtual 3D city and landscape models. An increasing range of applications has raised the demand for high quality 3D data.
The CityGML Data Quality Interoperability Experiment (CityGML QIE) aims to provide implementation recommendations for CityGML data based on data specification and a conception of the validation workflow. Another goal of the Interoperability Experiment is to provide a suite of essential quality-checking tools to carry out quality assurance on CityGML data. This will be accomplished by evaluating the quality of existing CityGML data as well as the quality of CityGML sample data sets that have been specifically developed for this experiment with available quality checking tools. Data requirements and recommended implementation guidance will be defined from the insights obtained by these experiments and may serve as input to extend and refine the CityGML standard and provide better implementation guidance for CityGML.
The CityGML QIE will be carried out as a joint activity between OGC, SIG3D and EuroSDR. Organizations and individuals are invited to participate in the activity by providing CityGML test data and/or test tools, defining requirements, or carrying out tests using a variety of different test tools. Participants need not be OGC members.
The experiment’s initiators plan to start with a kick-off meeting September 9-10, 2014 at the Kadaster office in Amsterdam. Please contact CityGMLQIE@lists.opengeospatial.org for further information and to register as a participant.
