通用型森林资源调查GIS系统设计与实现

Design and implementation of the universal forestry resource survey GIS

本文分析了PDA森林资源调查采集软件的应用现状,针对现有开发模式和系统框架重用度低、通用性差、难于维护扩展的问题,提出了基于"数据字典"的通用型森林资源调查GIS系统软件的开发方案。采用相关开发工具,进行了系统实现;实践证明,该系统具有良好的通用性和可扩展性。

The paper analyzed the application status of the forestry resources survey software on PDA, by considering the lower reusability, poor versatility and difficulty to maintain and extend of the current development model and system framework, it proposed a solution of the universal forestry resources survey GIS based on ＂data dictionary＂ . At last it implemented the universal system by using Microsoft Visual C ＋ ＋ and Embedded Visual C ＋ ＋ IDE development tool. The universal system has been applied to the investigation of forest resources in Fujian Province task, which proved the system＇ s versatility and scalability.
