小海子水库地形测量平面控制网的建立

Establishment of Topographic Survey plane Control Network in Xiaohaizi Reservoir

本文总结了小海子水库地形测量平面控制网的建立,给出了在大面积、长距离、大比例尺测图范围内,采用不同的平面控制网确保测图精度。经对所测三角网各种短边精度的统计分析,探讨影响短边测角精度的有效途径,使测角精度达到最或然值。

This paper summarized es ablishment of topographic survey plane control network in Xiaohaizi reservoir It gives the data based on which one can use various plane control networks within a large area a long distance and a survey with big scale under affirming survey precision, According to statistical analysis of various short side precision of measured triangwlar network this paper studies on the effective way of affecting short side measuring angle precision so as to make measuring angle precision reach the most prcbalility
