【Abstract】 ion: Because of notional or semantic fuzziness and imprecise measurements, many data in spatial databases are imprecise. In this case, linear objects are not crisp lines but some narrow zones that include true lines. And we must distinguish the topological relations between these linear objects. In this paper, the descriptive methods of uncertain linear objects in the present are summarized, and the 9-intersection model for describing topological relations between crisp linear objects is applied. Then the topological relations between uncertain linear objects are described and determined by a qualitative analyzing method.更多还原
