摘要
介绍了RTK技术坐标转换的两种方法,通过对不同地区的测区进行坐标转换,分析了不同坐标转换参数下的应用。RTK技术测得的是WGS-84坐标,而我们实际中需要的大多是北京54、西安80坐标系。以此问题为基础,阐述了坐标转换的分类和应用步骤。
This article introduce some methods of RTK coordinate conversion,according to the example of GPS RTK measuring,RTK coordinate transformation of technology is introduced in this paper two methods based on coordinate transformation in different parts of the survey area,different application of coordinate transformation parameters are analyzed.WGS-84 coordinates measured in RTK technique,and what we actually need is mostly Beijing 54,Xi′an 80 coordinate system.Based on this problem,classification and application of coordinate transformation steps are described.
