摘要
GPS技术是我们测绘工作的一次技术革命，不仅改变了我们的作业模式，还大大的提高了我们的工作效率和工作精度。但是GPS是建立在WGS-84坐标系统下的，而我们通常使用的是北京54坐标系或西安80坐标系，这就要求我们在工作时进行必须的坐标转换，求解转换参数。本文对坐标系之间的转换从理论研究到实际的工作实践作相应的论述。
GPS mapping technology is our job in a technological revolution, not only changed our mode of operation, but also greatly enhance our work efficiency and accuracy. However, GPS is built on the WGS-84 coordinate system, and we used 54 in Beijing or Xi＇an 80 coordinate system coordinate system, which requires us to be at work when the coordinate transformation, solve the transformation parameters. In this paper, the conversion between the coordinate system from the theoretical research to the actual work practices accordingly discussed the matter.
