基于套件技术的一站式GIS系统框架结构研究
|
摘要
传统GIS平台在集成应用方面,体量大、费用高、功能大而全,尤其对于非专业用户缺乏性价比,缺乏直接面向用户的专题性解决方案。在开发方面,模块可复用性低、系统扩展性差。针对这些问题,分析服务架构的特点及其模块之间的协作方式,采用套件、总线技术,提出一种基于套件技术的一站式GIS系统框架结构,该框架的套件设计赋予套件层高灵活性,能够在GIS系统中灵活组装以达到设计目的。总线的设计支持功能服务的分散组合,提升系统的可扩展性、伸缩性。总体上实现了一种松散的系统体系结构,支持功能服务的分散组合及可复用,并在实际中得到应用,验证了该框架结构的可行性与科学性。
The application integration of traditional GIS platforms are of large volume, full function and high cost,while its cost-performance ratio is very low especially for those non-professional users as it lacks directly user-oriented solutions of thematic problems. Regarding modular development, modules of traditional GIS platforms are of low reusability and poor system scalability. To solve these problems, this paper analyzes the characteristics of the service architecture and cooperation mode of modules and proposes an architecture of one-stop GIS based on suite technology using the kit and bus technology. The proposed architecture uses the kit and bus technology, and makes the suite layer combine flexibly. The bus design supports the decentralized combination of functions to improve the extensibility and scalability of the system. In general, a loosely coupled system architecture is developed to support the decentralized combination and reusability of system functions. The architecture has been applied to a one-stop management system.Results indicate that the architecture is feasible and flexible.
