摘要
GPS导航对于森林资源调查、护林防火、造林作业设计等林业野外作业工作效率的提高具有重要作用。在分析GPS通用导航系统山区导航问题的基础上,针对山区导航信息缺乏的问题,设计了以轨迹导航与筛选模型为核心的自助导航模型。以此为基础,设计并实现了基于PDA的导航信息采集与智能导航为一体的山区道路自助导航系统。该系统可为野外工作人员提供灵活、丰富的信息采集与快捷、方便的导航服务。
GPS navigation plays an important role in improving the efficiency of forest resources survey, forest fire prevention and afforestation operation design. Based on analysis of the application problem of the common GPS navigation in mountain areas, a self-navigation model was designed including the track navigation model and track selection model. A self-navigation system on PDA was thus developed,which integrated self-collection of navigation information and self-navigation. This system can provide flexible and convenient navigation for people in mountain areas.
