基于ArcSDE和SQL Server2000洪水灾害信息数据库的设计研究

Design of Integrated Database of Flood Information Based on ArcSDE and SQL Server2000

空间数据库是目前地理信息系统应用的重要支撑部分.洪水灾害数据存在数据量大、种类多、保密强等特点,所以洪水灾害信息数据库的设计也不完全等同于其他空间数据库的设计.结合实际工作,对洪水灾害信息数据库建设中ArcSDE和SQL Server2000的配置,以及用户安全管理、数据入库参数(分块大小、金字塔技术、压缩方式)等技术方法进行了探讨.

Spatial database plays an important role in the application of GIS. Because flood information data is large and varied, and some of it is sensitive. The design of integrated database of flood information is different from other spatial database. The configuration of ArcSDE and SQL Server2000, user security management and parameters of inputting data （such as tile size, pyramid, compression） in constructing integrated database of flood information are discussed.
