矿山测量专业毕业论文（Graduation thesis of mine surveying specialty） The graduation design (Thesis) Title: digital measure and practice experience: professional chart method of mine surveying this design theme: digital mapping is implemented, combined with the actual acquisition method mainly from the mapping control network design and layout, measured using total station of scattered points and scattered data points by three study; also a very detailed description of the total station in digital mapping application, and the scheme of large scale mapping; the final measure conforms to the requirements of large scale digital topographic map Honghe County Planning Bureau using total station, digital mapping in the mapping precision, mapping cycle is short, that is, characteristics the rapid establishment of city large scale basic geographic information database, has been a number of city planning and construction management leadership favored and reference. The basic idea of digital mapping is the terrain and geographical elements (or analog) conversion to digital quantity, and then use the computer to process it, get the electronic map with rich contents, need to have graphics output devices (such as display, plotter) output topographic map or thematic map graphics. The process of converting analog quantities into numbers is often referred to as data acquisition. It is through the collection of relevant information and timely drawing data recorded on the terminal, and then the collected data to the computer through the data interface in the interior, and a computer for data processing, and then through the interactive screen edit form drawing data file, the plotter controlled by computer automatic drawing for topographic map by the end of disk, CD-ROM and hard disk storage medium storing electronic map. Although digital mapping products still provide graphical topographic maps, they preserve terrain models and geographic information in digital situations. Key words: digital map
