多源水利遥感数据的一体化管理机制研究

摘要

随着水利遥感数据及产品在水利业务中的普遍应用，存储和管理问题日益成为限制数据应用的瓶颈。针对水利遥感数据及产品的存储管理问题进行研究，以空间数据库引擎技术为基础，提出面向数据库的多源水利遥感数据一体化管理机制。开发并实现基于 C/S 模式的多源水利遥感数据管理系统，利用空间数据库引擎屏蔽数据的复杂性和异构性，通过统一的接口实现水利遥感数据的数据库存取。经过系统测试，证明该系统具有良好的数据存取性能，能够为上层的水利应用提供可靠的数据保障%　　As water remote sensing data and its products used universally in water conservancy business, data storage and management problems become the bottleneck for data applications increasingly. This article focuses on water conservancy remote sensing data and product’s storage and management problems. Based on the Spatial Database Engine technology, it raises multi-source remote sensing data integrated management mechanism for water conservancy which is database-oriented. It designs and develops a multi-resources remote sensing data management system for water conservancy which is based on C/S mode. Using spatial database engine, it can shield the complexity and heterogeneousness of different data. And it provides a uniform interface for database data access. By tested, it shows that the system has favorable data access performance. It can offer a reliable data guarantee for the upper water conservancy applications.
