基于国家防汛抗旱指挥系统二期工程的地理空间数据库设计研究

Geospatial Database Design for National Flood Control and Drought Resistance

随着国民经济和社会的高速发展,对水利工作提出了更高的要求,同时也提升了防洪抗旱的工作标准。地理空间数据库是防汛抗旱综合数据库的组成部分之一,为各业务应用提供地理空间数据服务。本论文主要给出了地理空间数据库的总体设计及数据模型设计,同时提供了更新维护设计。目的是形成数据库建设的自动化、流程化、标准化和规范化。

With the rapid development of the national economy and society, there are higher requirements for the development of water conservancy work. At the same time, the working standards for flood control and drought resistance have also been promoted. Geospatial database is one of the components of Flood Control and Drought Resistance integrated database, which provides geospatial data services for various business applications. This paper mainly provides the general design and data model design of geospatial database. The update maintenance design is also provided. The purpose is to form standarded database construction in an automation, process, standardization and normalization way.
