基于PDA的森林资源样地调查记录系统的设计与实现

Study on the PDA-based forest resources data collection system

本文介绍了一种基于PDA并将GPS、MobileGIS等技术进行综合集成的森林资源连续清查样地调查(一类调查)应用系统的设计和实现,并对其系统结构、工作原理、硬件构成、软件设计等进行了论述。该系统将野外调绘和数据采集融为一体,改变了传统的野外调查方式,实现了数据采集自动化,大大提高了外业和内业的工作效率。

The design of a system for field survey and data collection in the National Forest Inventory (NFI)( the first level forest inventory)is introduced in this paper, which is based on the technologies of PDA,GPS and Mobile GIS. The principle and structure of the system is detailed together with its hardware and software implementation. Compared to the traditional way for field data acquisition, this method can be used in data collection with great efficiency.
