摘要:
基于PDA的森林资源数据采集是数字林业的重要内容,其核心工作就是开发高效智能化数据采集软件.该文通过分析森林资源数据野外采集特征和应用需求,以软件模式设计与分析理论为基础,提出一套有较强通用性和可扩展性的森林资源数据采集PDA软件设计方案.通过对数据输入流程的各部分进行分析,将共享部分进行封装成为通用的功能,对需要扩展和发生变化的部分参数化,通过参数设置达到智能化设置输入范围、配置用户界面及数据逻辑关系的目标.该方案能够满足当前森林资源一类、二类、三类野外数据调查的需要,并能适应将来调查因子扩展和变化的需要,极大地提高了林业野外信息调查采集工作的效率.
Abstract:
Forest resource survey with PDA is one of the important tasks of digital forestry,and its key job is to develop an efficient intelligent data input software.Based on requirement analyasis of forest resource inventory software,by applying software design patterns technique,a data input software of forest resources on PDA was designed with high extensibility and powerful flexibility.By checking all stages of data processing,encapsulating and ing the general logic and function as base class and parameterizing the varied parts of different tasks, a smart parameter design can define the range of inventory factors,user interface and data logic relations.The software can meet the requirement of forest resource suvey,management and design task only by parameters configuration now and future,and improve the efficency of forest field information input.
