| Abstract: | The researching of uncertainty and quality control of spatial data is considered as an important basic theory in GIS. So several phases of this issue are introduced in detail in this thesis, and actuality of the academic researching in GIS is briefly given. Meantime, facing to the status quo of GIS application,some opinions are put forward on the strategies of data quality control. |
