两种坐标系之间的转化探讨

摘要

The second national land survey result data needs to use Xi'an geodetic coordinate system 1980, while the original coordi- nate system of surveying results is Beijing geodetic coordinate system 1954. In order to realize full, simple and convenient conversion of results between two types of coordinate system, and easy conversion parameter solving, this paper summarizes the conversion model and derives new parameter, facilitates the programming of coordinate conversion, and improves the accuracy of conversion.%全国第二次土地调查成果资料要求采用1980西安坐标系,各地原有成果坐标系多为1954年北京坐标系,为使两个坐标系下成果相互转换简便充分,转换参数求解方便,将转换模型推理归纳得出新的参数,为坐标转换程序编写提供便利,同时提高转化精度。
