摘要
实现不同坐标系坐标的相互转换主要有七参数法、四参数法等。从五洋水电站首级控制网建立的具体实践出发,介绍四参数法在起算数据统一中的应用方法和计算步骤及库区首级控制网的建立方法。
7 parameters and 4 parameters methods are the main coordinate transformation methods between different coordinate systems. This paper introduces the application and calculation process of 4 parameters in the unification of initial numerical data, at same time, points forward the first order control network establishment method of reservoir area.
