| Abstract: | 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. |
