摘要
通过对广东省内地形和经度跨度不同的5个区域进行长度投影变形情况分析,给出了广东省地市建立平面独立坐标系的建议,同时可为自然资源主管部门在地市平面独立坐标建立审批时提供参考意见。
Based on the analysis of the length projection deformation of five regions with different topography and longitude span in Guangdong Province,this paper gives some suggestions on establishing independent coordinate system in guangdong province.At the same time,this paper can provide reference for natural resources authorities in approving the independent coordinate system scheme for prefecture-level cities.
