水土保持监测系统信息平台实现方法(I)——信息平台结构设计与实现

文章以密云水库上游水土保持监测系统工程为背景,说明了监测系统信息平台的设计过程和实现方式。信息平台采用数据库技术,基于Oracle和ArcSDE构建了三层服务结构的数据库体系;采用数据库、参数库与模型库分开管理的方式,实现了海量多元数据的集成存储与管理。数据库中数据类型包括矢量、栅格、影像等空间数据及多媒体、文本、数值等非空间数据。其中重点就数据库逻辑结构、数据物理存储和数据组织管理方案,以及数据库物理结构设计等内容进行了说明,同时也说明了信息平台在实际业务中的应用。

Implementation of Information Platform of Soil Conservation Monitoring Information System(I) ——Design and Implementation of Platform

Based on the project of soil conservation monitoring information system in the upper basin of Miyun reservoir,the information platform has been constructed and implemented to store and manage the different format data. On the support of Oracle and ArcSDE,multi-source,multi-scale and different formats data have been stored and managed in the uniform platform.This paper expounds key steps during the process of design and implementation of the platform.The paper focuses on the logical structure of the information platform and discusses how to physically store spatial data in the database and how to organize different format of spatial data to find the optimal storing way. Finally,the key technology related to the construction of the database and the application to practice is discussed.
