本科毕业论文 数字测图方法与精度分析 ON THE CITY FESTIVAL’S MARKETING STRATEGY 学院（部）： 测绘学院 专业班级： 测绘10-2班 学生姓名： 杨凡 指导教师： 张国卿 年 月 日 摘 要 人类正迈向信息社会，随着科学技术的发展，计算机、GPS定位仪、全站型电子速测仪及数字测图软件的应用，大比例尺地形图的测绘技术有了飞速发展，数字测图广泛用于测绘生产、水利水电工程、土地管理、城市规划、环境保护工程等部门。作为测图技术现代化水平的标志之一，数字测图技术以其高精度、高效益逐渐代替传统测量模式。现在，随着实时动态定位（RTK）技术的推广和应用，数字化技术将进入全新境界。 本文就传统测图方法与数字化测图方法的优缺点进行了对比说明，就目前数字测图中常用的几种方法与GPS RTK技术进行了研究，就其原理和操作进行了说明，在说明的过程中列举了有关的数据，以加深理解。数字测图是一项过程复杂而繁琐的工作，要得到高质量的数字地图，必须对起其测图过程的各个环节进行质量检查和精度控制，所以我们在熟练掌握数字测图方法的同时还要懂得精度分析，本文列举了各种方法实施过程中常遇到的问题以及解决方案。 关键词：全站仪、GPS RTK、精度分析 ABSTRACT Human beings are towards the information society, with the development of science and technology, computer, GPS tracking entirestation type, electronic speed measuring devices and digital mapping software applications, large scale topographic map surveying technique has the rapid development, digital surveying and mapping production is widely used in water conservancy and hydropower projects, the land management, urban planning, environmental protection engineering department. As the symbol of modernization level technology of digital mapping technique, with its high precision, high efficiency gradually replaced traditional measurement model. Now, with real-time dynamic positioning (RTK) technology, digital technology and application will enter a brand-new realm. Based on traditional mapping method and digital mapping method compares the advantages and disadvantages of current digital surveying, several methods and GPS RTK technology was studied, and the principle and operating, in the process of data, to deepen our understanding. Digital mapping is a complicated process and work, want to get high quality digital map, the mapping of up to each link of the process of quality inspection and control precision, so we in digital mapping method of mastering the also know precision analysis, this paper lists various methods implement process middling problems and solutions
