基于SOA的WebGIS框架探索

Study on architecture of WebGIS based on SOA

面向服务架构(SOA)是一种适用于变化环境的软件开发体系架构,能够在一定程度上消除当前W ebGIS数据和操作难于共享的瓶颈。文中从概念框架、层次结构、实现框架、服务开发方式等几个方面对基于SOA的W ebGIS框架进行了设计;并以此框架为立足点,利用基于XML的W eb Service技术设计实现了重庆市渝北区土地利用规划管理信息系统,初步验证了框架的可行性和有效性。

SOA（Service-Oriented Architecture） is an architecture of software design suitable for changing environment, in which the difficulty in the sharing of data and operations can be removed to a certain extent. Conceptual framework, hierarchical relations, implementing framework and service implementing modes of WebGIS architecture based on SOA were designed. As a case study, a land use planning management information system for Yubei district, Chongqing city was implemented through XML-based Web service technology. The feasibility and validity of the architecture has been verified preliminarily.
