基于一体化思想的海图更新数据模型

Data Model of Updating Nautical Chart Based on Integrative Idea

海图更新一直是海图生产与应用领域研究的重点问题。在分析了我国海图数据特点的基础上,给出了异构海图一体化更新的模式与方法,设计了实现该模式所必需的海图更新数据模型;并利用SQL Server数据库构建了相应的海图更新数据结构;最后讨论了利用海图更新数据实现异构海图一体化更新的关键技术。

Nautical chart updating is always the key and hot problem in field of chart production and application. Based on analyzing the characteristic of chart data in China, the integrative updating mode of chart and data model of updating nautical chart were discussed, and then data structure was designed using SQL Server System, the key technique of integrative updating chart was studied through the updating data.
