摘　　要：介绍了测绘产品质量监督检验工作中对数字地形图产品数学精度检测的一种算法。该算法通过遍历展绘的检测点坐标,依次定位显示检测点视图窗口,然后采用人机交互操作方式实现地形图数学精度的快速检测统计与评分。文章结合地形图产品质量检验项目,以LISP语言为例,对算法的基本设计思路进行了说明与实现。最后通过工程实例对程序的实用性和有效性进行了测试,达到了预期结果。Introduce an algorithm for mathematical precision detection of Digital Topographic Map products in the survey-ing and mapping product quality supervision and inspection .Mathematical precision of topographic map shall be efficiently de-tected ,statistic analyzed and scored ,which is by traversing the detecting points ’ coordinate ,displaying the view window of their position in turn,and then operating by human-computer interaction mode till completed .Based on topographic map quality in-spection items,taking LISP as an illustration,the basic idea of the algorithm was illustrated and implemented .Finally through an example of test about the practicability and validity of application ,which achieved the desired effect .
