| description | A steadily growing number of application fields for large 3D city models have emerged in recent years. Like in many other domains,
data quality is recognized as a key factor for successful business. Quality management is mandatory in the production chain
nowadays. Automated domain-specific tools are widely used for validation of business-critical data but still common standards
defining correct geometric modeling are not precise enough to define a sound base for data validation of 3D city models. Although
the workflow for 3D city models is well-established from data acquisition to processing, analysis and visualization, quality
management is not yet a standard during this workflow. Processing data sets with unclear specification leads to erroneous results and
application defects. We show that this problem persists even if data are standard compliant. Validation results of real-world city
models are presented to demonstrate the potential of the approach. A tool to repair the errors detected during the validation process
is under development; first results are presented and discussed. The goal is to heal defects of the models automatically and export a
corrected CityGML model. |
