Querying moving objects is a crucial ingredient in many applications involving moving objects. Being able to query the location of an object is important to achieve services like E-911, m-commerce, fleet management, etc. However, moving objects have inherent uncertainty in their location information. Obtaining the exact location of an object at every time instant is infeasible. In this paper we aim towards designing an algebraic query language that can query and reason about trajectory properties of moving objects both with precise and uncertain trajectories.
