基于开源GIS的森林资源管理信息系统设计与实现——以江苏省云台山为例

Design and implementation of forest resources management information system based on open source GIS

在借鉴国内外森林资源管理信息系统(FRMIS)开发技术及开源GIS平台架构的基础上,针对当前商业GIS组件开发成本较高、开放性较差、开发灵活性较低等问题,以江苏省云台山GIS系统架构及开发为例,借助MS.NET Framework V3.5及开源GIS组件MapWinGIS两大开发平台,通过AXMap控件及功能接口实现系统GIS基本功能并定制空间数据编辑模块,通过数据交互中间件技术无缝链接系统逻辑层构建Post gre SQL/Post GIS数据库,结合MS GDI+图形库封装GIS制图功能控件等,开发出低成本、高开放、扩展性强、灵活度高的新型森林资源管理信息系统。

Based on the open source GIS platform architecture,we learned from the latest forest resource management information system（FRMIS） developing technology at home and abroad.To solve the shortcomings among current commercial GIS component such as high developing cost,poor opening-up and low developing flexibility etc.,we developed a GIS system framework of Yuntai Mountain on the two major development platform i.e.MS.NET Framework V3.5 and Map Win GIS open source GIS components.By integrating AXMap controls and functional interfaces,we implemented the basic GIS functions and customized the spatial data editing module.On the other hand,by using data exchange middleware technologies,we built the postgre SQL/Post GIS spatial database following the seamless linkage programming on the logic layers.Furthermore,we packaged the GIS mapping function control on the MS GDI＋graphics library to extend the spatial capability of the traditional graphic interface.Our study explored a low-cost,high opening-up and flexibility model of forest resources management information system development.It would provide certain significances to the development of forestry information modernization and make contributions to the relevant software industry development in the near future.
