海洋测绘垂直基准的建立与转换

摘要

This paper presents some points about vertical datum which catches more and more attention in hydrographic survey and charting, include the present situation of vertical datum, the relationship among the vertical datum planes and so on. In order to realize seamless joining of coastal topographic map and bathymetric chart,the transformation technique between the datum planes of coastal topographic survey and bathymetric survey is also researched.%在我国海洋测绘采用的多个基准面的复杂进程中,垂直基准的建立与实现已开始初露端倪并越来越引起大家的重视.就海洋测量垂直基准的现状、垂直基准面间的关系、海岸带地形测量与水深测量基准面转换技术等方面进行探讨,以期实现海岸带地形图和水深图的无缝拼接.
