This International Standard specifies the conceptual and logical data model and the exchange format for
geographic data bases for Intelligent Transportation Systems (ITS) applications. It includes a specification of
potential contents of such data bases (Features, Attributes and Relationships), a specification of how these
contents shall be represented, and of how relevant information about the database itself can be specified
(meta data).
The focus of this International Standard is on ITS applications and emphasizes road and road related
information. ITS applications, however, also require information in addition to road and road related
information.
EXAMPLE 1 ITS applications need information about addressing systems in order to specify locations and/or
destinations. Consequently, information about the administrative and postal subdivisions of an area is essential.
EXAMPLE 2 Map display is an important component of ITS applications. For proper map display, the inclusion of
contextual information such as land and water cover is essential.
EXAMPLE 3 Point-of-Interest (POI) or service information is a key feature of traveller information. It adds value to enduser
ITS applications.
The Conceptual Data Model has a broader focus than ITS applications. It is application independent. This
allows for future harmonization of this International Standard with other geographic database standards.
Diese Internationale Norm legt das konzeptionelle und logische Datenmodel sowie das Austauschformat für die geografischen Dateien bei intelligenten Transportsystemen fest. Es sind Spezifikationen für die potentiellen Inhalte solcher Dateien (Eigenschaften, Attribute, Verbindungen), Spezifikationen für die Beschreibung der Inhalte und die relevanten Informationen, wie die Dateien selbst spezifiziert werden können, enthalten.
