摘要
空间数据及其质量客观上决定了GIS不确定性的产生和存在。描述了客观属性的空间数据的不确定性,以GIS空间线状实体位置不确定性理论为研究核心,采用不确定性引出GIS不确定性论题,阐述了若干相关概念,指出了空间数据与GIS的相互关系,以及研究进展。
It is spatial data and its quality that decides GIS uncertainty in fact. This paper describes uncertainty of spatial data that express impersonality attributes. Positions uncertainty of GIS spatial linear entities are primary research objects. Uncertainty is introduced first in this paper, then GIS uncertainty is induced, and some relative concepts are described too. Relationship between spatial data and GIS is indicated, as well as the last research progress.
