Entropy and its state of arts on research of spatial data uncertainty

Abstract

总结了熵的产生、发展、特性及其应用,讨论了熵与不确定性的关系;针对空间数据不确定性问题,总结了基于熵的空间数据不确定性研究成果,提出了应用混合熵作为统一测度来度量空间数据不确定性的设想。 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.
