CityGML Quality Interoperability Experiment
1 Introduction
1.1 Preface
The aim of the CityGML Quality Interoperability Experiment was to define data quality requirements for a general CityGML data specification, to provide recommended
implementation guidance for 3D data, and to provide a suite of essential quality checking tools to carry out quality assurance on CityGML data. The data requirements and
recommended implementation guidance were obtained by experimentation and may serve as input to extend and refine the CityGML standard. These requirements and guidance
should meet the OGC Membership and community thirst for better implementation guidance for OGC standards, in this case CityGML.
The QIE was carried out as a joint activity between OGC, SIG3D and EuroSDR.
1.2 Scope
This OGC Engineering Report specifies the results and findings of the CityGML Quality Interoperability Experiment. Guidelines were developed for the following concepts:
Definition of data quality; Data quality requirements and their specification;
Quality checking process of CityGML data; and Description of validation results.
The desired outcomes of this Interoperability Experiment are to improve the interoperability of CityGML data by removing some ambiguities from the current
standard and formally defining data quality requirements for a general CityGML data specification. Further, the results of this work provides to the community organizations
invested in capturing, procuring, or utilizing CityGML data recommended implementation guidance for 3D data and a suite of essential quality checking tools to
carry out quality assurance on CityGML data.
