基于Service Portal的地理信息共享模式探索及实现
|
摘要
近年来,随着网络技术、计算机技术的发展以及面向服务架构的地理信息系统的深入研究和应用,基于网络并通过Web-Service的形式提供地理信息服务已经成为地理信息共享的主要方式,同时伴随着全国范围内“数字城市”、“数字省区”建设工作的展开,在网络上会有越来越丰富的地理信息服务资源,如何实现这些分布的资源的有效集成和应用是我们面临的重要课题。
基于Portal的概念,本文提出了研究基于Service Portal的地理信息共享的模式,并通过构建地理信息服务门户,作为一定区域内地理信息服务资源统一集成和访问的一站式入口,进而更加有效地促进地理信息的共享。基于此,本文主要研究了以下几个方面的内容:
地理信息网络服务和共享是当前GIS领域研究的热门课题,论文首先系统地研究和总结了当前地理信息服务和地理信息共享的相关理论,同时论文还研究了门户相关理论及其在地理信息领域的相关应用。
然后,论文在以上相关理论研究基础之上,探索并概括出了基于Service Portal的地理信息共享模式的概念及其特点,并据此提出了通过构建地理信息服务门户,实现分布式地理信息服务的集成与共享的观点,同时论文也对该地理信息服务门户的整体结构进行了研究。
接着,论文研究了构建地理信息服务门户中的若干关键技术;系统地探讨了服务门户的构建模式;设计了适应地理信息服务门户特点的元数据描述体系;探讨了服务门户构建过程中的地理信息服务统一描述-发现-集成的模式及其解析与集成关键技术。
最后,基于以上的研究,论文对该服务门户进行了总体架构设计,在总体设计基础之上又对服务门户的主要组成部分进行了详细的设计,根据总体设计和详细设计,论文最终编程实现了该服务门户的原型系统,具体验证并实现了本文所提出的基于Service Portal的地理信息共享模式。
These years,with the development of network technology and computer technology,and also with the in-depth research and application on geographic information system,which has the service-riented architecture,the providing of geographic information service,which is based on the net and adopts the form of Web-Services,has become the main method of geographic information-sharing,at the same time,going with the outspread of the construction of digital city and digital province in the scope of countrywide,there will be richer and richer geographic information service resources,how these resources can be significantly integrated and applied has become an important subject we faced.
Based on the concept of portal,this paper has brought forward the idea of promoting the process of geographic information-sharing more efficaciously,that is,doing research on the geographic information-sharing model based on Service Portal,and building the geographic information service portal as the one-stop entrance of the unified integration and accessing the geographic information service resources in certain area.Based on this,the main research work of this paper can be described as followings:
Geographic information web services and sharing is the popular research subject in current GIS field, firstly,this paper has been done some research and summerization systematically on related theories about geographic information service and geographic information-sharing,and at the same time,this paper has also done some research on the theories of portal and its applications in geographic information field.
Then,based on the theoretical research work above,this paper has explored and summarized the concept and features of the geographic information-sharing model based on Service Portal,and accordingly,this paper put forward the viewpoint of achieving the integration and sharing of distributed geographic information services through building the geographic information service portal,and this paper has also done some research on the overall structure of this portal.
Afer that,this paper has done research on several key technologies,during the process of building the geographic information portal;and has also systematically explored the build model of service portal;and designed the metadata description system,which adapts the features of geographic information service portal;and finally discussed the model of unified description-discovery-integration of geographic information services and the key technology of parsing and integrating these services.
Finally,based on these research above,this paper has done the overal architecture design,and then,based on this,this paper has also finished the detailed design for the main parts of this service portal,according to the overal and detailed design,this paper has eventually developped the prototype system by programming,and also concretely verified and implemented the geographic information-sharing model proposed by this paper.
