摘要 数学精度是测绘项目质检中一个重要的质检元素。测绘成果通常在CAD软件下进行采集和编辑成图。传统的精度检查以人工计算为主,因此设计一套在CAD环境下进行数学精度检查的程序提高准确度和效率很有必要。程序设计主要分为展点、采坐标和精度计算。程序的实现能够极大地提高测绘项目的质检效率。 Mathematical accuracy is an important quality inspection element in surveying and mapping project quality inspection.Survey-ing and mapping results are usually collected and edited into maps using CAD software.Traditional accuracy checks are mainly based on manual calculations,so it is necessary to design a program for mathematical accuracy checks in a CAD environment to improve accuracy and efficiency.Program design mainly consists of point definition,coordinate acquisition and accuracy calculation.It can greatly improve the qual-ity inspection effciency of surveying and mapping projects.
