Recently many applications like fire simulation and tsunami monitoring bring more interests in the extents of moving objects. Present research usually focuses on the positions of moving objects. As a result, tracking the continuously changing extents of spatial objects is becoming increasingly necessary. This paper proposes a novel model to represent the irregular shape of moving objects that may have parts and support the querying of the predicated near future extents. The method is capable of representing objects evolving in one-, two- and three-dimensional space. We also provide user-defined precision level to decide the quality of modeling. Our experimental results performed on stimulation dataset show that the model is effective for representing and querying the extents of moving spatial objects.
