摘要
介绍了泰顺县GPS基础控制网布设与施测、坐标系统选择与利用、基线解算与平差等过程,结合泰顺县山区地形特征,深刻分析了坐标系统选择的问题,将WGS-84的大地坐标系统与现行实用的坐标系统,如1954年北京坐标系统、1980年西安坐标系统以及引测的温州坐标系统紧密的联系起来,从而实现坐标系统之间实时精确的转换,为"数字泰顺"实际应用奠定了坚实的基础。
A systematic introduction is provided of the deployment of fundamental control network of GPS in Taishun County,its surveying methodology,its selection and application of coordinate systems,its calculation of reference lines and other processes such as adjustment.The problem of the selection of coordinate systems is analyzed in depth in view of the special characteristics of Taishun＇s mountainous terrain.WGS-84 terrestial coordinate system and the one currently in use,such as Beijing 1954 Coordinate System,Xian 1980 Coordinate System and primitive Wenzhou Coordinate System,are closely consolidated.This makes it possible for coordinate systems to accurately transform in real time into each other,laying a solid foundation for the practical applications of ＂digital Taishun＂.
