摘要
主要研究了4D产品(DEM、DOM、DRG、DLG)空间数据库结构设计,将4D产品通过空间数据库引擎ArcSDE存储在大型商业关系数据库管理系统Oracle8i中。在Oracle中可以建立不同的关系表来存储一些4D产品。由于采用关系数据库管理空间数据符合OpenGIS规范,这将增加空间数据的互操作性,并能使GIS融入IT技术的主流。
At present, the construction of ＂Digital Earth＂ has become global hotspot. One of the characteristics of ＂Digital Earth＂ is open platform, component technology and dynamic interoperability, to which file system is not adapted at large. Under the circumstance only relation-full spatial database is suitable to these needs. This paper focuses on how to store up 4D products such as DOM, DEM, DRG and DLG in Oracle 8i, one of large business RDBMS, by spatial database engine.
