摘要: This paper presents a model of data for mobile objects. The is represented by spatial-temporal classes with mobility aspects, and represents the route trajectories where objects move. problem databases inaccuracy approached. A trajectory uncertainty free considered, spatial operators are defined to capture uncertainty. Another important concept added profile historical movement, that is, an attempt increase precision prevision object positions not yet observed. Some simulations results shown, presenting efficiency some techniques calculating positioning prevision.
