Abstract

The idea of Conceptual Neighbourhood Diagram (CND) has proved its relevance in the areas of qualitative reasoning about time and qualitative reasoning about space. In this work, a CND is constructed for the Qualitative Trajectory Calculus (QTC), being a calculus for representing and reasoning about movements of objects. The CND for QTC is based on two central concepts having their importance in the qualitative approach: the theory of dominance and the conceptual distance between qualitative relations. Some examples are given for illustrating the use and the potentials of the CND for QTC from the point of view of GIScience.
