Error Analyzing and Quality Control to Map Scanning Digitization Data

分析了基于扫描数字化GIS数据生产过程中的误差来源,针对各种误差提出了质量控制方法和一些质量控制指标,并结合实例作了精度分析。可以为地图扫描数字化减小误差、进行质量控制提供一定的借鉴。

This paper analyzed the error resource of map scanning digitization based on the process of GIS data produce. The error control method is suggested and the quality control index is advanced in this paper. Meanwhile, the error of the testing data is analyzed. It can be used for reference of decreasing error and quality control in the course of map scanning digitization.
