Dealing with moving objects necessitates having available complete geographical traces for determining exact or possible locations that objects have had, have or will have. This i...
This article introduces new similarity measures between trajectories, in order to detect uncommon behaviors. These measures are used to find the most common trajectories in a seq...
In this paper we are interested in storing and perform OLAP queries about various aggregate trajectory properties. We consider a data stream environment where a set of mobile objec...
In this paper, we present an OLAP framework for trajectories of moving objects. We introduce a new operator GROUP TRAJECTORIES for group-by operations on trajectories and present ...
