测绘常用坐标系转换框架设计分析

针对现阶段各类坐标系间的高精度转换在定位导航等方面的重要理论意义和实用价值,根据现有的坐标转换模型设计了坐标转换框架,在坐标转换框架中确定一个中间坐标系,各个坐标系统之间的转换都通过中间坐标系来完成,从而建立框架下所有坐标系间的公共关系。新加入的坐标转换关系继承了坐标转换框架下原有的坐标转换关系,简化了新坐标系与框架下已有坐标系间的转化工作,坐标转换精度为20 cm,验证了使用坐标转换框架的可行性。

Design and Analysis of Coordinate Conversion in Surveying and Mapping

In view of the present all kinds of coordinate system of high precision conversion in positioning and navigation, important theoretical significance and practical value, according to existing coordinate conversion model designed coordinate transformation framework, in the coordinate transformation framework were identified in an intermediate coordinate system, the conversion between different coordinate systems are through the intermediate coordinate system to complete, so as to establish the framework of all coordinates between public relations.New additions to the coordinate transformation between inherited the coordinate transformation framework under the original coordinate transformation relation, which simplifies the new coordinate system and the framework of the existing coordinate transformation and coordinate transformation precision is 20cm to verify the feasibility of using coordinate transformation framework.
