 空间数据质量是地理信息系统分析结果是否准确和合理的重要因素,也是地理信息系统研究领域的重要课题。在分析了影响空间数据质量因素的基础上,运用模糊数学理论对GIS中的空间数据质量评价方法进行了探讨,提出了一种科学有效的评价思路,为空间数据质量评价提供了依据。 更多还原

【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. 更多还原
