基于数据引擎思想的GIS数据集成与共享

The integrating and sharing of GIS sata based on the technology of data engine

通过对数据库系统数据共享的实现原理进行分析,探讨了采用数据引擎思想实现GIS数据的集成与共享的原理与方法。并在VC++环境下,以标准地球空间数据交换格式(VCT)作为基础,实现了常用GIS数据的集成与共享。

Through analyzing the principle of data share in the database system,this paper discusses the principle and method of realizingintegration and share of GIS data by using data engine method.It states how to achieve the high integration and share of GIS data on the basic of VCT in VC++.
