地形测量技术设计（Design of topographic surveying technology） This post will be edited by huangzhaoy at the end of 2012 Design of topographic surveying technology Chapter 1 overview The purpose and task of topographic survey To meet ACheng hongxing reservoir planning management and the need of engineering construction, in order to a high starting point, high standard to prepare hongxing reservoir development and construction planning, expand the area of about 10 km2 in the latter topography measurement. The department of surveying and mapping engineering of heilongjiang university of engineering is planning to complete the work of both internal and external industries in June 2006 if undertaking this task. The main tasks of this survey are: 1. The use of advanced GPS (global positioning system (GPS) measurement technology, establish basic e-class GPS control network, hongxing reservoir construction planning, and for the future of the planning and construction to provide reliable measurement control points. Control area about 12km2. 2. On the basis of the e-class GPS network, the scope of the surveyed area and ophiolites in duolie, traverse control network layout level, for the topographic survey and the topographic map update construction lofting measurement and to provide enough to count the data. 3. Using the computer-aided mapping technique of whole field data collection, the map of 1:1000 scale topographic map is about 10km2 to form a complete and accurate data file of topographic map. 4. Provide a map of 1:100 topographic map of the area with a height of 1m and a 1:20 topographic map. Profile measurement area ACheng hongxing reservoir 42 km away from Harbin, in the center part of the surveyed area east longitude 127 ° 08 north latitude 45 ° 34 surveyed area is located in xiao xing guang-cai zhang gain ridge -odd arteries, mountainous, mountain ranges, a thin north reed groove in the north part of the surveyed area, south to hongxing commune homes, west Yao Gutun, east t
