Web地图服务的集成共享研究

Research on Integration and Share of Web Map Services

Web服务技术为GIS空间数据的互操作提供了全新的、有效的解决途径,越来越多的GIS软件支持OGCWeb服务规范。如何在单个应用程序中集成多个服务器上的Web地图服务是本文要解决的核心问题。首先阐述了本文的研究意义,然后对OGCWeb地图服务及开发所采用的主要技术分别作了介绍;提出了Web地图服务集成共享平台的体系结构和相应的功能设计,并利用Servlets、JSP、JavaScript等技术对其进行了初步实现。

More and more GIS software support OGC Web Services specifications for interoperability and information eTPhange. How to integrate and share web map services from internet or intranet is the hot point in GIS application and the research. This paper focuses on design and development of the integrating and sharing platform of Web Map Services. The paper first discusses why to establish the platform, then introduce basics of OGC Web Map Services and main techniques of implementing the integrating and sharing platform. The Implementation of the platform is realized by means of Servlets, JSP, JavaScript.
