AN APPLICATION DOMAIN EXTENSION FOR STORING VALIDATION RESULTS OF CITYGML STRUCTURES

Abstract. With the increase of applications using 3D models as base for visualization or simulation the requirements for having valid models rises. While there are many programs that validate models there is no standard for storing the results. The simulation programs also may implement their own validation checking to verify if a model can be simulated which may be error prone or not extensive enough for their purpose. This paper provides an extension for the CityGML format to store the validation result. With the available validation information software using the extension can improve their process of working with models containing errors. CityGML model manufacturers may also improve their creation process of the model as well as deliver them validated.
