摘要
根据林业野外有害生物调查中,对照片、坐标和方位角等信息的实际需要,设计实现了一个基于PDA的林业有害生物调查系统。系统以遥感图像和林相图作为野外调查的底图,利用内置GPS模块进行导航,采集调查点坐标,利用摄像头采集病虫害照片,利用内置电子罗盘获取照片采集时的方位角信息,记录病虫害信息,采集的结果直接保存为空间数据格式。此系统显著提高了野外调查的工作效率,为林业有害生物调查提供了一种先进的技术手段。
According to the practical requirement for photo, coordinates and azimuth angle in forest pest investigation, a forest pest investigating system is designed and implemented. Within the system, remote sensing images and forest maps are used as base maps, the embedded GPS is used for navigation and location data collection, the embedded camera is used to take photos in field, the electronic compass is used to capture azimuth angles, and an interface is used to input descriptive attribute data. The result of investigation which be directly saved as Spatial data format. This system can greatly improve the work efficiency and provide an advanced methodology for forest pest investigation.
