摘要
目前,荆江水道地形测量的船台平面定位基本利用网络CORS模式进行,但其测量成果属于CGCS2000坐标系,只有将其转换到BJ-54坐标系中,才能保证资料的连续性和可利用性。因而,不同坐标系统间转换参数的正确求解的方式与方法是CORS技术应用的关键。本文结合长江中游荆江河段水道地形测量,讨论分区坐标转换的方式方法,为类似工程测量提供参考。
At present, the boats plane positioning uses CORS mode in the Yangtze River waterway topographic survey project, but its measurement results belong to the CGCS2000 coordinate system, which only convert to BJ-54 coordinate system. For the ribbon topography survey, correct solution of different coordinate system conversion parameters is the key of COILS technology application. In this paper, combined with the Yangtze River channel topographic survey engineering practice, the conversion method of partition coordinate in this ribbon topography engineering was analyzed and discussed, and preferable results were achieved.
