【摘要】 通过空间数据库引擎技术(SDE)可以有效地实现空间数据在数据库中的管理。但各种空间数据库引擎在储存数据格式上的不一致,都会影响各引擎相互间数据操作的效率。文中以ESRI公司的ArcSDE和Oracle公司的Oracle Spatial为例,通过分析以上两种空间数据库引擎的数据格式,解决了从ArcSDE向Oracle9i Spatial的空间数据的转换问题。更多还原

【Abstract】 Through using the spatial database engine technology, the management of spatial data in a database may be realized effectively. But due to the different formats in various spatial data engines, the efficiency of data conversion between various spatial database engines may be effected. The paper taking ESRI’s ArcSDE and Oracles’s Oracle Spatial for examples, researches on the data conversion between ArcSDE and Oracle9i Spatial by analysing each spatial database engine.更多还原
