This specification is limited to generic definitions of terms and methods for describing and measuring the quality of digital map databases defined according to the format of this International Standard. It provides the foundation for defining quality levels according to user's and/or producer needs. Applying this standardized quality description scheme can help to ensure that different digital map databases can be evaluated and compared with respect to their quality characteristics. Dedicated application data content and quality requirements can be based on this specification.
Data Content and Data Quality depend mainly on application requirements, i.e. different applications need individually composed datasets with a particular content and quality. However, even within one application area such as car navigation, the required map information might differ depending on the functionality of a certain system or the services supported by an application.
