海道测量数据库建设的关键技术研究

摘要

简要介绍了海道测量数据资源现状和应用服务需求及海道测量数据库建设的必要性和目标要求,总体说明了海道测量数据库的建设内容、技术架构和服务能力,深入探讨了海道测量数据库建设过程中涉及的数据库建模、数据分级存储、通用数据采集引擎、地形数据保真处理和海量离散数据网格化等多项关键技术及解决思路.最后提出了下一步工作思路和研究方向.%The data resources status and information service requirement of hydrography are introduced briefly,the necessity and goal of the construction of hydrographic survey database are also educed. The development items, technology framework and service capability of hydrographic survey database are described totally. The several key techniques are researched deeply, including geospatial database modeling, data classifying storage, common data gathering engine, terrain data precision preserving, huge discrete points gridding,and so on. Lastly, the development route and research goal are reviewed in the future.
