| 摘 要： | 凭借其开放和可自我描述的格式体系、完善丰富的空间数据表达技术、灵活多变的应用模式生成方法,经过短短几年时间的发展,GML迅速在空间数据的建模、传输与交换、集成与共享和空间互操作等诸多G IS研究与应用方向中发挥着重要作用。本文从国内与GML相关的研究课题、博、硕士学位论文和公开发表的核心期刊中文论文等几个方面,深入分析了GML在中国的研究进展,并就GML规范研究、GML技术研究和GML应用研究三个方面提出了国内GML研究与应用面临的挑战、急需解决的问题。研究结果表明:目前国内形成了众多特色鲜明和高水准的GML研究团队与研究成果,但随着GML研究与应用的逐步开展,国内GML低水平重复性研究工作的弊端也日益暴露出来。因此,丰富与完善GML规范,深化GML技术研究,建立多层次的GML应用技术模式,开展基于GML的空间服务应用,发展GML软件工具,积极参与GML国际规范的修订,将是未来我国研究人员开展GML研究工作的重点。

| Abstract: | Due to its opening and self-described format system,abundant spatial data expression technology,flexible application mode generation method,GML quickly plays an important role in many GIS research and application directions such as spatial data modeling,transmission and exchange,integration and sharing after several years of development.This paper deeply analyses research development of GML in China on aspects of domestic GML related research project,doctoral and master's degree thesis as well as published Chinese papers by core journals.In addition,this paper proposes challenges confronting domestic GML research and application and crucial problems to be resolved in the direction of GML development from three aspects: GML specification research,GML technology research and GML application research.From the analysis of research subject,the focus of GML research has changed from the initial expression of GML data,spatial data modeling of industry,spatial data conversion and integration and visualized research of GML,to GML's internal mechanism which based on the principle of the core technology of GML,the way to realize GML and interoperability between applied technologies.From the analysis of doctoral and master's degree thesis and the Chinese papers published on core journals,we can see that the research of GML was emphasized on application before 2004 but at of GML technology and combination between it and space services after 2004.The research of GML application was mainly concentrated on the support of WebGIS framework,spatial data sharing and interoperability and so on,while that of GML technology focused on GML's storage,index,query,compression and pattern matching and so on.Papers and studies on GML put forward the challenges and urgent problems in domestic GML research and application from three aspects: the GML specification,GML technology and GML application.In GML norms aspect,China should promote the institution of national relevant sharing standards based on GML.In technical research aspect,domestic researchers should strengthen the technique and method's study on GML resolution,GML storage,GML query,GML index and GML compression and transmission.In applied research aspect,it is very necessary for professionals in GML field to establish professional application mode,fractionize the applied layers of spatial data,and improve the shared obstacles in GML application system. |
