Abstract:
Geodata represents the state of a real world phenomenon at some point in time. Multiple, differently interpreted reference times can be associated to the same datum yielding an n-time-dimensional (nD) problem. This reference time, however, is often ignored, reduced or managed "manually" on application level. We propose a new approach for nD temporal geodata management encapsulating and hiding this complexity. The Geography Markup Language (GML) and a transactional Web Feature Service (WFS-T) are used for standard compliant data exchange. Its feasibility is proven by a reference implementation and applications. Thus, the main achievement of this paper is the presentation of a new nD temporal data management approach using time point representation and its application to GML-based forestry applications.
