基于Oracle Spatial的配电网GIS数据存储方法

Data storage method of power distribution GIS based on Oracle Spatial

针对配电网地理信息系统(GIS)数据存储技术方面目前存在的数据不一致、存取速度慢等问题,提出了一种基于OracleSpatial的数据存储方法。对比目前主要的数据存储方式,介绍了对象关系型数据库在空间数据存储方面的优越性,分析了利用OracleSpatial组件存储GIS空间数据的原理,并且提供了一个该方法的应用实例。该实例的程序使用Java语言编写,而且采用了面向GIS应用的开源代码。程序的运行结果表明实例所采用的数据存储方法能够在配电网GIS中实现空间数据和属性数据的一体化存储。

Aiming at the data inconsistency and low access rate in data storage of PDGIS （Power Distribution Geographic Information System）,a data storage method based on Oracle Spatial is proposed. Compared with current major methods of data storage,the advantage in spatial data storage of the ORDB （Object Relational DataBase） is presented. The principle of GIS spatial data storage with Oracle Spatial is analyzed with an application example. Its program is written in Java, importing some open source codes designed for GIS applications. The result shows that the data storage method adopted in the example realizes the integrative storage of attribute data and spatial data of PDGIS.
