The continuous development of wireless networks and mobile devices has motivated an
intense research in mobile data services. Some of these services provide the user with …

Spatial Databases is the first unified, in-depth treatment of special techniques for dealing
with spatial data, particularly in the field of geographic information systems (GIS). This book …

The domain of spatiotemporal applications is a treasure trove of new types of data and
queries. However, work in this area is guided by related research from the spatial and …

Moving Objects Databases is the first uniform treatment of moving objects databases, the
technology that supports GPS and RFID. It focuses on the modeling and design of data from …

Spatiotemporal applications, such as fleet management and air traffic control, involving
continuously moving objects are increasingly at the focus of research efforts. The …

Among the various types of spatio-temporal queries, the most common ones involve window
queries in time. In particular, timestamp (or timeslice) queries retrieve all the objects that …

In moving object environments, it is infeasible for the database tracking the movement of
objects to store the exact locations of objects at all times. Typically, the location of an object …

We consider spatio-temporal databases supporting spatial objects with continuously
changing position and extent, termed moving objects databases. We formally define a data …

In this paper, we attempt to approximate and index a d-dimensional (d≥ 1) spatio-temporal
trajectory with a low order continuous polynomial. There are many possible ways to choose …

A proper understanding of the general nature, potential and obligations of electronic
services may be achieved by examining existing commercial services in detail. The …
