摘要
为满足对水土流失相关数据高效存储与管理的需求以及支撑水土流失评价业务,需要建立高效的水土流失评价空间数据库。首先介绍了建立水土流失评价空间数据库的关键技术(Arc GIS空间数据库引擎(Arc SDE)和Oracle),接着从数据内容、系统架构、建设原则、数据存储等方面详细阐述了该空间数据库的设计与实现,最后介绍了数据的检查及入库工作。实践表明,建立的数据库实现了对水土流失评价相关数据的高效存储与管理,可满足实用需求。
In order to meet the need of efficient storage and management for related data of soil and water loss and support the business of evaluation, a highly efficient spatial database for soil and water loss evaluation needs to be constructed. This article firstly introduces the key technology (ArcGIS Spatial Database Engine (ArcSDE) and Oracle) of constructing spatial database for soil and water loss evaluation, then elaborates the design and implementation of this spatial database from the aspects of data content, system architecture, construction principle, data storage and so on, and finally explains the work of data check and data input. It turns out that this spatial database built in this paper implements the highly efficient storage and management for related data of soil and water loss evaluation and can meet the practical need.
