Anforderungen und Prüfungen für die Validierung von CityGML-Modellen#

The requirements are the basic building blocks for a validation plan to validate CityGML models. For naming conventions and definitions, see fundamentals.

A requirement can be validated by one or more checks. A check validates one or more requirements on a model. Each check can have preconditions. If these preconditions are not met, the check is not executed. A distinction is made between:

• Schema Requirements
• Geometry Requirements
• Semantic Requirements
