Oracle Spatial空间数据在ArcSDE中的图层注册

Layer Register of Oracle Spatial Data in ArcSDE

将Oracle Spatial空间数据注册成为Arc SDE图层,是在Oracle数据库中完成Oracle Spatial空间数据向Arc GIS格式转换,实现Oracle Spatial空间数据与其它格式空间数据互操作的可行方法.分析了采用Arc SDE API和sdelayer命令进行图层注册的过程,提出一种基于SQL语句的适用于海量空间数据的图层注册方法.与传统的图层注册方法相比,新的图层注册方法的易用性、安全性和运行效率得到了很大提高.

Registering the Oracle Spatial data as a layer of ArcSDE is a feasible way of converting data from Oracle Spatial to ArcGIS. It realizes the interoperation with Oracle Spatial data from the spatial data in other format. This paper analysis the register process using ArcSDE API or using sdelayer command and proposes an effective layer register method using SQL language for mass spatial data. Compared with the traditional layer register method, this new layer register method was improved in aspects of usability, security and efficiency.
