针对传统数字地形图精度检测工作繁琐且效率低下的问题,从精度检测快速化、流程化的需求出发,提出了一种快速实现地形图数学精度检测与评定的技术方法。该方法以流程化的方式检测数学精度,各检测模块由功能组件(算法)构成,最终评定结果由Access数据库统一存储。分析应用实例可知,该方法提高了检查效率,非常合适数字地形图的数学精度检测与评定。

The traditional topographic map accuracy detection is cumbersome and inefficient. In this paper, we proposed a method of rapid detection and evaluation of topographic map accuracy, based on the demand of rapid detection and process f low. This method processed the accuracy detection in a process-oriented manner. Each detection module consisted of functional components(algorithm), and the final evaluation results were stored by Access database. From the analysis of the example, the conclusion shows that this method can improve the detection efficiency, and is very suitable for the detection and evaluation of the accuracy of digital topographic map.
