基于Oracle Spatial实现多源空间数据集成

探讨了空间基础数据的集成问题。在分析了目前地理信息集成的3种方式后,提出使用大型关系DBMS作为各种格式空间数据的容器,空间数据引擎作为空间数据出入该容器的通道。并以Oracle9iSpatial为例,分析了OracleSpatial的空间对象模型,使用OracleSpatialJava类库设计并实现了一种以XML为信息交换标准的空间数据转换系统,将空间数据接口统一集成到OracleSpatial中。

Multi-resources Space Data Integration Based On Oracle Spatial

This paper probes into the integration of the space data,after analyzing three ways of the current geographical information integration,puts forward a proposition of using the large-scale relation DBMS as the containers of different space data and using the space data engine as the path through that the space data come in and go out this container,and takes Oracle Spatial as an example,analyzes the space object model of Oracle Spatial,and uses the Oracle Spatial Java Library to realize a space data converting system that regards XML as the information exchanging standard and integrates all the space data interfaces into Oracle Spatial.
