使用FME实现数字地形图数学精度的自动统计

Automatic Statistics of Mathematical Accuracy of Digital Topographic Maps by Using FME

介绍了运用空间关系原理,使用FME软件编写数字地形图数学精度自动统计模板,实现自动输出标准格式的位置精度统计结果,极大地提高了精度统计效率,解决了目前数学精度统计方式中检测效率低下、输出结果还需二次整理等问题。

This paper introduces the use of spatial relation principle,uses FME software to compile the mathematical accuracy automatic statistics template of digital topographic maps,achieves automatic output standard format of position accuracy statistics results,greatly improves the accuracy of statistical efficiency.The problems such as low inpection efficiency and secondary sorting of output results are solved in the current mathematical accuracy statistics method.
