相对独立坐标系与国家坐标系联系方法研究

Research on the Relation between Relative Independent Coordinate System and National Coordinate System

建立完成相对独立坐标系统之后,一方面需要与国家坐标系相联系,以便独立坐标系成果更好地延续和利用;另一方面有利于独立坐标系成果的继承和更新。建立相对独立坐标系与国家坐标系之间联系的过程实质上是不同坐标基准转换的过程,需要依据实际情况选择适当的转换模型,建立合理的转换关系,通过多种方案的计算和对比,以转换精度来评价转换效果。已知的建立两者之间联系的方法有很多种,本文结合实例对比各方法的优劣与适用条件。

In order to make the independent coordinate system achievement more effectively used and renewed. We need establish a connection between independent coordinate system and national coordinate system after the independent coordinate system have been established. The process of establishing the relation between relative independent coordinate system and national coordinate system is essentially the process of transformation of different coordinate benchmark. There are many ways to establish a connection between the two. In this paper,the advantages and disadvantages of each method and the applicable conditions are compared with examples.
