摘要
本文对当前国土资源系统实际测绘工作中所遇到的多套空间坐标数据相互转换的突出问题进行了深入的研究,并就其实现方法和过程进行了较为详细地描述,针对实现过程中采用的关键技术加以说明,并通过具体实例分析了该方法的可靠性和实用性,为即将开展的"二调"成果的利用工作提供测绘保障服务。
When we survey land resource working,we perhaps meet lots of coordinates data conversion problems. The paper studies deeply on coordinates data conversion in many kinds of reference frame, describes its methods and processes in detail. And then, the paper explains the key technique in the processes and analysis the dependability and practicability of method by example. The research will serve the using of the result of second national land survey.
