摘　　要：DLG是测绘数据的核心产品,地理空间框架数据的核心组成部分,其成果精度决定了工程的质量,以往成果精度检测主要以手动检测为主,效率低、精度差。本文基于Visual Lisp语言开发了DLG位置精度自动检测程序,通过制作检测点和原始坐标点之间点对,自动生成检测记录报告,这种方法基本避免了检测过程中的人为误差,极大地提高了工作效率,改进了现有的数据生产方法。DLG is the core product of mapping data and core component of geospatial framework data. Its accuracy determines the quality of the project. Manual accuracy detection method is mainly used before, it is inefficient and with poor accuracy. In this paper, a new DLG position accuracy detection program has been developed based on Visual Lisp language by making point pairs of the detection point and the original point so as to output the inspection records report automatically. This new method greatly improves the working efficiency.
