【摘要】 系统以面向对象的建模方法和三层体系结构(ThreeTiers)进行设计,采用组件开发技术,实现软件模块的重用和软件的共享,利用MapX和MaXtreme组件分别开发了客户端/服务器和浏览器/服务器两种模式的林业专题GIS,且利用网络达到无缝集成。本研究选取陕西省宁陕县火地塘林场和宁东林业局1992年的二类调查数据及林相图、地形图等相关图件作为系统运行的验证,结果证明该方法是可行的。更多还原

【Abstract】 The system is designed with object oriented modeling and three tiers, devolved with component based development technology. Moreover, forestry thematic GIS is developed based on MapX and MapXtreme with Client/server and Browse/server models, and seamless integration with network is realized. The system meets the need of forestry units and the public.This paper researches and sets up the forest resource information management system with the data of Ningshan County and Ningdong Bureau of Forestry. The result of study is feasible.更多还原
