| Abstract: | The spatial data quality is one of the important factor for detecting the accuracy and reasonableness of geographic information system analysis.On the basis of analyzing the factor for influencing the spatial data quality,it discussed the method of spatial data quality assessment in GIS by fuzzy mathematics theory,and put forward a appraisal mentality which has provided the basis for spatial data quality estimate. |
