一种扩展地理网络互操作模型

OpenNet:an OGC-SFS expanded geographic network interoperability model

针对不同地理网络GIS应用间信息集成和功能共享难于实现的问题,该文提出地理网络互操作模型OpenNet。该模型通过定义一系列与平台无关的地理网络对象和方法,扩展和完善了开放地理信息协会简单要素规范,并解决地理网络GIS互操作问题。OpenNet包括对象模型和操作模型两部分,前者定义网络对象并规范对象方法,后者定义网络类和网络对象两个层次的修改操作。该文以ARCGIS和MapGIS两种主流GIS平台上的地理网络互操作为例,验证了OpenNet模型的可行性,证明它能够实现数据和功能的互操作,并支持与平台无关的通用地理网络应用系统的开发。

In order to meet the needs of information integration and functionalities sharing in different geographic network GIS applications, this paper presented the geographic network interoperability model OpenNet. It extended and improved OGC simple features specification and solved geographic network GIS interoperability by defining a series of geographic network objects and methods. The OpenNet consisted of two parts, namely object model and operation model. Object model defined network objects and object methods, and operation model defined the modification operations of network classes and network ob- jects. This paper verified the feasibility of OpenNet model through the case study of geographic network in- teroperability between two mainstream GIS platforms ArcGIS and MapGIS, and supported the develop- ment of common geographic network applications independent on different platforms.
