摘要
通过几内亚某铝土矿公路项目实例,简要介绍了项目特点,国外常采用的UTM投影及其特点,重点分析了投影变形问题、独立坐标系的建立方法,介绍了项目控制网的测设处理方法。
Through a Guinea bauxite highway project,this article briefly introduced the characteristics of the project,different points of the UTM projection and the Gauss projection,focus on the analysis of the distortion of projection problem,establishing method of independent coordinate system,introduced the project control network. Different projects have different characteristics,we should analyze the practical situation of each project,adopt the different processing method.
