摘要
首先分析了GIS(GeographicInformationSystem)互操作,指出GIS互操作应包括GIS数据互操作和GIS处理功能互操作两个方面。GIS数据互操作采用GML(GeographyMarkupLanguage,地理标记语言)编码可以较好地实现;而通过对组件GIS思想的扩展和对组件注册模型的分析,GIS处理功能互操作以地理信息服务的形式出现。最后提出了采用Java技术构建的GIS互操作模型的系统结构。
Firstly analyses GIS Geographic Information System interoperability. GIS interoperability have two facet-GIS data interoperability and GIS founction interoperability. Using GML (Geography Markup Language) is a good approach to achieve GIS data interoperability; through extending the thinking of component GIS and analysing the model of component registration, GIS founction interoperability can be solved better. Finally,an architecture of GIS interoperability is proposed.
