摘要
分析了现有GIS数据的管理方法,指出在现有条件下利用对象关系数据库管理空间数据的优越性。在详细分析了OracleSpatial进行空间数据管理机制的基础上,针对性地提出直接在对象关系数据库中存储矢量地理时空数据的方法。以土地利用变更的时空数据组织为例,在OracleSpatial中实现了空间数据、时间数据和属性数据的一体化管理。
The choice of management methods of vector data will affect not only the efficiency and the safety of data transfer,but also the applied prospect of the software.The thesis analyzes management methods of GIS data in common use,points out advantages of spatial data management with Object-Relational database.After introducing the principle of Object-Relational database and its application method,this paper gives a method of accessing spatiotemporal vector data in an Object-Relational database.Oracle9i is chosen for the research in this paper.The research proves that it is feasibility and validity to access the spatiotemporal vector data in Object-Relational database,and provides path of spatiotemporal data storage in Web environment.
