Focus on movement data has increased as a consequence of the larger availability of such
data due to current GPS, GSM, RFID, and sensors techniques. In parallel, interest in …

Since the late 1970s, relational database technology has been adopted by most
organizations to store their essential data. However, nowadays, the needs of these …

With the large-scale adoption of GPS equipped mobile sensing devices, positional data
generated by moving objects (eg, vehicles, people, animals) are being easily collected …

Advanced technologies in location acquisition allow us to track the movement of moving
objects (people, planes, vehicles, animals, ships,...) in geographical space. These …

Several works have been proposed in the last few years for raw trajectory data analysis, and
some attempts have been made to define trajectories from a more semantic point of view …

Trajectory data allow the study of the behavior of moving objects, from humans to animals.
Wireless communication, mobile devices, and technologies such as Global Positioning …

The analysis of movements frequently requires more than just spatio-temporal data. Thus,
despite recent progresses in trajectory handling, there is still a gap between movement data …

Field-road segmentation that automatically divides a trajectory into a sequence of field/road
segments is an important component in segmentation process for the trajectories of …

Mobility of people and goods is essential in the global economy. The ability to track the
routes and patterns associated with this mobility offers unprecedented opportunities for …

In this paper we present a formal framework for modelling a trajectory data warehouse
(TDW), namely a data warehouse aimed at storing aggregate information on trajectories of …
