Abstract

The quintessence of the Qualitative Trajectory Calculus – Double-Cross (QTCC) is to describe the interaction between two moving objects adequately. Its naturalness has been studied before, both theoretically and by means of illustrative examples. Using QTCC, this paper extends the fundamental approach to interactions of configurations of multiple moving objects. In order to be able to optimally store and analyse trajectories of moving objects within QTCC, a transformation from traditional quantitative information to QTCC information is needed. This process is explained and illustrated by means of an example. It is shown that once this transformation process is done, the storage and analysis of real world moving objects from the point of view of QTCC, enables querying of moving objects.
