摘　　要：随着遥感技术、计算机技术、光电传感技术及航天技术的迅速发展,地理空间数据的采集手段越来越多。针对这些地理数据质量存在的一系列的问题,利用层次分析法确定各个因素的权重,使用缺陷扣分法计算,对数字线划地图数据在数据完整性、逻辑一致性、位置精度、属性精度进行计算分数,采用模糊综合评价方法分别从上述4个方面检查数据质量,使其更好地为人们日常生活服务。With the rapid development of remote sensing,computer,photoelectric sensing and aerospace technology,there are more and more geospatial data collection means.In response to a series of problems in the quality of geographic data,an analytic hierarchy process was applied to determine the weight of each factor,and the defect deduction method was explored to calculate the scores for the data integrity,logical consistency,location accuracy,and attribute accuracy of the Digital Line Graph data.Finally,the fuzzy comprehensive evaluation method was introduced to check the data quality from 4 aspects to improve its application.
