基于 ArcGIS Server 9.0和 J2EE 构建多层结构的森林资源 WebGIS

阐述了基于ArcGIS Server 9.0和J2EE技术的多层结构森林资源WebGIS的开发思想和各功能层的实现技术,在开发过程中以"瘦客户"模式作为本系统的结构模式,并采用MVC设计模式对系统功能进行分割。同时,以大兴安岭塔河林业局森林资源数据为例,介绍了森林资源空间数据的发布、森林资源WebGIS系统的组成以及其界面的定制、主要功能等。结果表明:ArcGIS Server 9.0、J2EE技术与MVC设计模式的综合使用,使整个森林资源WebGIS系统的开发效率、数据安全性、跨平台可用性、系统功能可扩充性和使用灵活性等方面较传统的双层体系结构系统得到了较大的优化和提升。

A Multi-Tiers WebGIS of Forest Resources Based on AreGIS Server 9.0 and J2EE Technology

The developing thoughts and realization technique of multi-tiers forest resource WebGIS were introduced based on ArcGIS Server 9.0 and J2EE technique. A "Thin Client" mode was selected as the systematic framework mode during the developing procedure. And MVC design pattern was applied to separate system functions aiming to improve system development efficiency and functional expandability. Taken the forest resource data of Tahe Forestry Bureau of Daxing'an Mountains as an example, release of spatial data of forest resources via internet, constitution of forest resource WebGIS, customization of display interface, and main functions were introduced in brief. Result shows that the integrated application of ArcGIS Server 9.0, J2EE technique, and MVC could better optimize and improve the development efficiency, data security, platform usability, extension and usage agility of system functions compared with the traditional system with double-level structures.
