摘要: 描述了空间数据互操作、互操作GIS的概念,提出了一种互操作GIS模型———开放式虚拟模型。基于公共虚拟接口的思想,讨论了模型的虚拟性和开放性,用以解决空间数据和GIS软件功能的互操作。基于OVM模型,利用GIS软件Arc/Info 8和GeoStar 4进行了分析处理层的互操作实验,验证了模型的正确性和可操作性。

Abstract: This paper brief by introduces the interoperability and summarizes several main models of GIS interoperability. Then the interoperable GIS model——Open Virtual Model ( OVM) is given. OVM tries to resolve some problems in accessing distributed heterogeneous component databases transparently and operating the collaboration of GIS software function. An idea of common virtual interface is put forward. Based on the idea, the open and virtual OVM are analysed.
