各坐标系向2000国家大地坐标系转换软件研究

Software Development For The Conversion Of Each Coordinate System To CGCS2000

2018年7月1日起,自然资源部要求全面使用2000国家大地坐标系。而由于历史原因,铁路系统采用的基础测绘成果仍有部分是基于西安80坐标系或北京54坐标系。如何快速将现有测绘成果转换到CGCS2000坐标系是当前亟待解决的问题。基于此,本文介绍了一套支持多数据类型、多转换模型和多转换方案的坐标转换软件,在过渡时期提供坐标转换支撑。

Since July 1,2018,the Ministry of Natural Resources requires the full use of the CGCS2000.Due to historical reasons,the basic mapping results adopted by the railway system are still based on the Xi'an 80 coordinate system or Beijing 54 coordinate system.How to quickly convert existing mapping results to CGCS2000 is an urgent problem to be solved.Based on this, this paper introduces a coordinate transformation software that supports multiple data types, multiple transformation models and multiple conversion schemes, providing coordinate transformation support during the transition period.
