微电脑掌上森林调查系统研究

Research on Micro-Computer Handheld Forest Inventory System

以微电脑为硬件基础,采用嵌入式开发技术,将遥感、移动GIS,GPS及GPRS通信高度集成,开发了专门用于森林调查的微电脑掌上森林调查系统。文中详细分析了该产品的开发思路、关键技术、功能特点(包括图形图像显示、导航定位功能、野外测点、配准功能实地面积测量、资源调查图上距离面积量算等)及应用现状。

With micro-computer as hardware and embedded technology and after three years’ hard work, the micro-computer forest inventory system specially designed for forest inventory has been developed successfully by means of the integration of remote sensing, mobile geographic information system, GPS and the communication of GPRS. In this paper, the developing brainstorming, key problems, functions and features (such as showing vector map and image, navigating and positioning, surveying control point in the field, registering image, area surveying, resource inventory, distance and area surveying on map, etc.) and current application of this system are analyzed in detail.
