| 摘 要： | 矿区GPS控制网数据处理过程中,不可避免地会遇到长度投影变形的处理,在高海拔地区这个问题更加突出。通过矿区控制网实例,计算分析了长度投影变形,选择抵偿投影面建立矿区独立坐标系,限制了矿区长度投影变形,并通过解决方案的分析讨论,提出了高海拔地区处理矿区控制网长度投影变形的基本方法。

| Abstract: | In the date process of GPS control network in mining area,it shall be inevitable to treat the deformation of length projection,and this problem is more outstanding in high altitude region.In this paper,based on an actual GPS control network in mining area,the deformation of length projection is computed and analyzed,in which a compensation projection plane is selected to establish an independent coordinate system for mining area in order to restrict the deformation of length projection.After analyzing and d... |
