In this paper, the definition of entropy and its characteristics as well as its developments are summed up firstly, and then the relationship of entropy and uncertainty are discussed. Aiming at the problem of spatial data uncertainty, this paper sums up the proposed output of spatial data uncertainty based on entropy, and presents that hybrid entropy can be used as the uniform measure of spatial data uncertainty.
