数字化测绘技术在工程中的应用 摘要：数字化测图实质上是一种全解析计算机辅助测图的方法，它使得地形测量成果不再仅仅是绘制在纸上的地形图，而是以计算机存储介质为载体的，可供计算机传输、处理、多用户共享的数字地形信息。数字地形信息以其存储于传输方便、精度与比例尺无关、不存在变形与损耗，能方便、及时局部修测与更新，便于保持地形图现势性的巨大优势，极大地扩张了地形测量资料的应用范围，使其能在各部门发挥出更大的作用。本文主要研究全站仪和RTK数字化测图的方法和步骤,从使用条件、测量距离、测量误差和人员四个方面对两种方法进行比较，明确两种方法各自使用环境、条件和其优缺点。然后根据两种方法的使用环境、条件和优缺点得出它们各自在数字化测图方面的应用范围，并通过实例阐述RTK和全站仪联合测图在数字化测图中的优势。 关键词：数字化测图； 工程； 地形图 Application of digital mapping technique in engineering Abstract:Digital mapping is essentially a complete analysis computer aided mapping method, it makes the topographic survey results are no longer just drawn on paper topographic map, but in the computer storage media as the carrier, for computer transmission, processing, multiuser shared digital terrain information. Digital terrain information in its storage in the transmission convenient, precision and scale independent, there is no deformation and loss, convenient, timely local surveying and updating topographic map, to keep the potential huge advantage, greatly expanding the application range of topographic data, so that it can in the various departments to play a greater role.This paper mainly studies the total station and RTK digital measuring methods and steps of drawing, from the conditions of use, four aspects of measuring distance, measuring error and the personnel of the two methods, the two methods use environment, conditions and its advantages and disadvantages. Then according to the two methods use environment, advantages and disadvantages and come to their respective scope of application in the digital map, and through the examples of RTK and total station in digital mapping mapping with the advantage of.
