海洋空间信息基准技术进展与发展方向

摘要

简要分析了海洋空间信息基准的基本发展历程和当前的技术状态,梳理和评述了近年来关于验潮站垂直基准确定方法的改进与完善、验潮站控制下的垂直基准的实现形式、长期验潮站在维持垂直基准方面的作用、海洋潮汐模型构建、特征潮面模型构建与转换等有关海洋垂直基准及与其相关的海洋潮汐研究的主要进展,预测了海洋空间信息基准在海上高精度位置服务、垂直基准面及转换模型精化、空间基准应用等重点发展方向.%This paper briefly analyzes the basic development and technical situation of oceanic spatial information datum,reviews the main processes of oceanic vertical datum and correlative oceanic tidal study,such as improvement and perfect methods of determining tidal station vertical datum,realizing form of vertical datum controlled by tidal station,effect on maintaining vertical datum by long-term tidal station,oceanic tidal model establishing,and also construction and transformation of tidal datum,and then forecasts the key development directions of oceanic spatial information datum on high-accuracy marine position service,vertical datum and the transferring model refinement and spatial datum application.
