In order to promote the development of spatial information science and improve the research of GIS theory ,analysis of the current situation of spatial data uncertainty is processed.Throughout the domestic and foreign research results of the relevant literature,it can be known that spatial data random uncertainty is mainly elaborated and concluded from its basic theory and kinds;spatial data fuzziness is mainly studied from three aspects, such as the fuzzy nature and the resource, the representation and the processing method of spatial data.It is pointed that the problem and research direction of spatial data uncertainty that are the further improvement of the basic theory of stochastic uncertainty, attribute uncertainty research ,fuzziness of positional and attribute uncertainty.%为促进空间信息科学的发展和理论的完善,推动GIS理论的深入研究,需要对当前空间数据不确定性的研究状况进行分析和归纳.纵观国内外有关文献的研究成果可知:空间数据随机不确定性主要侧重于基本理论和种类方面的研究;空间数据模糊性主要从空间数据模糊性来源和性质、表示和处理方法等3个方面进行研究.空间数据不确定性急需解决的问题和研究方向,主要包括随机不确定性的基础理论的进一步完善、属性数据不确定性的研究、位置数据和属性数据的模糊性研究等方面.
