【摘要】 随着信息化水平的提高,基于位置的信息服务应用到社会的不同行业,用于政府宏观管理、辅助决策的各种专题地理信息系统对基础地理信息的需求也越来越多,越来越广。如何利用WebGIS技术实现高效的信息处理和管理决策,已成为广大地理信息行业共同关注的课题。通过研究基础地理信息分发服务技术,面向社会提供地理信息查询和地理信息数据及产品信息发布,这无疑是一种高效的技术手段,将极大地提高地理信息数据的利用率。论文首先分析了国内外基础地理信息分发服务现状,研究了基础地理信息数据类型和模式,针对传统分发服务模式的不足,提出了改进,接着阐述了WebGIS的理论与相关技术,并根据福建基础信息中心现有的基础地理数据以及对外提供数据成果的要求,结合基础地理信息数据的基础性、公益性、共享性等特点,确定了基础地理信息分发服务系统的功能模块、体系结构、开发平台,并以ArcIMS为地图服务器,使用Java、JSP、JavaScript等工具,建立了基于B/S架构并应用于Internet和Intranet不同网络体系的分发服务系统。目前该系统通过了验收,并正式投入使用。实际应用表明,该系统解决了基础地理信息分发服务过程中查询、订购以及提供等手续的信息化、自动化,满足用户方便快捷获取数据的要求,提高了成果分发服务的效率和信息化水平。本文既是一种设计方法的研究和试验,同时其研究结果可为有关部门提供参考。更多还原

【Abstract】 Along with the enhancement of infomationization level, Location-based information services apply to different professions of the society, more and more fundamental geographic information is needed by every special geographical information system which is used for goverment macroscopical management and assistant decision. So it’s very necessary to research how to make full use of WebGIS technology and how to process and manage the information. If we can provide the society with such services as inquiry, data and products issuance and data distribution of geography information on the basis of the study of the distributed service technology, we will improve the use of geography information.This paper first analyzes the status quo of the domestic and international distributed service in fundamental geographic information, studies the types and pattern of the fundamental geographic information products, in view of the traditional distribution service pattern’s insufficiency, proposes the improvement, then describes the contents and key technology of the distributed service. According to the existing basic geography data in Fujian and the requirements of its data provision and considering the characteristics of basic geography data, it determines the functional module, system structure, development platform of the distributed service system. With the ArcIMS as map server, using the tools such as Java, JSP and JavaScript, it designs and develops the distributed system based on B/S used in the internet and intranet. The practical application indicates that this system can make more convenient and automatic the procedures such as inquiry, ordering and providing data in fundamental geography information distributed service. It can satisfy the demands of all users to get the data much convenient and quickly and can also improves our distributed service efficiency.This paper is a study and experiment of a design method and its result can be served as a reference for the relative departments.更多还原
