近年来,在我国测量行业的高速发展中,人们对测量的认知有所加强,在建筑规划及施工测量中选用合适的测量方法逐步被人们重视,它不仅关系到建筑物定位的准确与否,还关系到测量过程中所消耗的资源与精力。合理的选用坐标系将会避免许多缺陷,本文将简析坐标系的方法,分析在地面测量过程中坐标系选用的原则,讨论坐标系中的边长问题,以及减小边长变形而选择平面直角坐标系的方法,就设计施工等阶段坐标系的转换等问题进行探析,为我国测量行业提出相关意见,希望能对相关工作人员有重要的研究意义和参考价值。
In recent years, in the rapid development of measurement industry in our country, people have strengthened their cognition of measurement. Appropriate measurement methods have been paid more and more attention in building planning and construction measurement. It is not only related to the accuracy of building positioning , But also related to the resources and energy consumed in the measurement process. Reasonable selection of coordinate system will avoid many defects. In this paper, we will analyze the method of coordinate system, analyze the principle of selection of coordinate system in the process of ground measurement, discuss the problem of side length in coordinate system, and select the plane Cartesian coordinate system approach to design and construction stage coordinate system conversion and other issues to explore for the measurement industry in China put forward relevant opinions in the hope that the relevant staff have important research significance and reference value.
