Especially in Chinas eastern coastal developed areas, the digital mapping almost accounted for most of the topographic mapping market. With the development of surveying and mapping science and technology, the all-digital topographic mapping in the modern computer - aided mapping technology support has developed into a high-tech mapping techniques. Total Station as the most widely used surveying and mapping equipment, which is electronic technology and optical technology combined with the development of optical measuring instruments, range finder, electronic theodolite advantages.Total Station is the practical large-scale digital mapping tool. The design theme: the implementation of digital mapping, combined with the actual mainly from the primary control, the layout of the root control network, the measured and the use of total station detail point collection methods and data processing Scattered point do explore; the very detailed exposition of the total station in the use of digital mapping, as well as large-scale mapping program; using total station to measure the large-scale digital topographic m
