3D city models are nowadays used in very different applications. Due to this, the commercial exchange and, thus, the demand for high quality data becomes more and more important. We describe a quality model that defines common parameters used for spatial quality measurement, especially when dealing with 3D city models. Therefore, we explore different representations of city models: the reality, the user's idea and the digital data set. A welldefined mathematical formalism which addresses the different quality parameters is presented. This formalism also helps to create algorithms for measurement and improvement of spatial data quality. The aim is to be able to define uniformed criteria which can be easily transformed into software. The implemented prototype serves as base for the evaluation in which we provide examples based on actual data sets using typical quality requirements.
