摘要
小地区测量控制网的建立方法通常采用导线测量，当测区没有高等级已知控制点而又要求采用国家统一坐标系统时，必须进行平面坐标和高程引测，如果已知控制点远离测区，使用导线测量方法进行引测既花费时间又增加误差，从而降低了作业效率和测量精度。结合马家堡校区测量控制网的建立，提出了一种用GPS技术进行平面坐标和高程引测，用全站仪导线建立小地区测量控制网的组合方法，实际测量结果证明了该方法的有效性与实用性。
The common method of establishing small region survey control net adopts traverse. However, when the area has no known high - class control point and requires the adoption of the national coordinate and height system, it is necessary to lead in the known coordinate and height. Using traverse to lead in known coordinate and height is not only time consuming but also increasing error if the known control point is far from the area, thus the work efficiency and measurement precision would be reduced. A combination method of leading in known coordinate and height using GPS and establishing the small region survey control net using TPS traverse is put forward in this paper. The feasibility and validity of the method is verified with actual measurement results.
