摘　　要：空间数据误差的种类包括源误差、操作误差等,通过分析空间数据误差产生的原因,减小空间数据误差,提高空间数据的质量,为计算机辅助决策和管理提供可靠的数据源。空间数据质量在建设数字地球、进行矿产预测和施工前的计算机模拟中发挥着越来越重要的作用,但空间数据的质量及其精度还未能引起足够的重视,由这些空间数据进行重新运算和组合产生的空间数据是不是最终需要的结果,缺乏其可靠性的分析工具。Geospatial data error includes source error and operating error, etc. It can afford a reliable data source for computer supplementary decision and administration by reducing these errors and improving the quality of geospatial data and analyzing the reasons that the data errors emerge. Nowadays, the geospatial data takes more and more important effect in the fields of building the digital earth, prospecting the mineral resources and simulating test of the computer before the construction. However, the importance of the quality and precision of geospatial data had not been attached, and cannot make sure that whether the results what get by the new operations and combinations of the geospatial data are what needed or not, because there are lack of reliable means.
