GIS Application Framework Based on SOA

Faculty of Information Engineering, China University of Geosciences, Wuhan 430074, China

摘要

摘要: 由于现有的框架及开发模式较难灵活地完成地理信息服务和应用系统多层次的融合，也难以快速地构建Web下地理信息系统(geographic information system，GIS)平台的应用系统.提出了一种新的基于面向服务架构思想(service-oriented architecture，SOA)的GIS应用框架，通过将工作流引入到空间信息处理中，并结合面向服务的业务端构造模式来简化用户GIS应用系统开发模式.并在此基础上实现了由系统框架、工作流引擎和表单3部分组成的面向SOA的GIS应用框架.实际应用表明，基于面向服务架构的GIS工作流能灵活的为不同的应用提供不同粒度和不同功能组合的地理信息服务，而基于SOA的表单能快速地构建业务系统，它们为GIS软件的集成和应用开发提供了一种新的思维.

Abstract: Since it's difficult to combine geographic information system (GIS) service and application system in multi-level flexibly and to build GIS Web application system quickly with the traditional framework and development method, we propose a new GIS application framework based service-oriented architecture (SOA) by introducing workflow into spatial information process, as well as simplifying user's development work through a service-oriented business model. On this basis, we have implemented a GIS application framework composed of the following three parts: system framework, workflow engine and forms. It has been proved in practice that SOA can offer various GIS services with different granularities and different function packages based on GIS workflow, as well as build business system quickly with form based on SOA. This model offers a new method to GIS development.
