摘要
结合地图数字化为ＧＩＳ采集空间数据的工作实际，对直角、直线数字化的数据处理的平差模型以及相应的精度评定方法进行了研究。作者认为，通过平差和评定精度，可以提高数字化的精度。
By combining with map digitization for GIS spatial data capture and LSA (Least Square Adjustment), the authors established the collation models and accuracy eveluation criteria for line rectangle features. The analysis results were also presented in the paper. The technical procedure adopted can also be used to realize efficient quality control of captured data in GIS spatial database.
