摘要

通过对地理信息系统(GIS)中空间异构数据源的访问和集成，对比了目前比较通用的几种集成技术和方法，讨论了空间异构数据集成的关键理论和技术，着重介绍了基于XML和中间件技术的集成方法。认为XML的最大优点在于它的数据存储格式不受显示格式的制约。随着RDF和VDB的发展，以XML作为集成层的数据描述工具和转换工具，建立具有多数据源集成能力的中间件，能适合空间异构数据源集成的需要。

Abstract

The article compares several universal integration techniques and methods via to access and integrate Spatial Heterogeneous Data on GIS. And in the paper

the authors discuss the key theory and technique of Spatial Heterogeneous Data Integration. Last

we give emphasis introducing the Integration method based on XML and Middleware technique. And we consider that the most major of XML is the independence of it's data storage format with display form. Along with the development of RDF and VDB

with data describing tool and transition tool based on XML by way of integration layer

middleware possessing capability of data sources integration is suit to the need of spatial heterogeneous data source integration.
