全球定位系统(GPS)的林区作业方案研究

Research on GPS Method for the Work in Forest Areas

全球定位系统(GPS)在林业中已经得到了广泛的应用,但如何确定切实可行的作业方案还有待研究。在福建永安市进行的GPS测量试验,分别针对林区地物进行了不同方式的测量,对其测量精度进行了比较和评价。提出了一种差分测量中测量区缺少基站点的解决方法,对不同的林业作业采用的GPS测量方案进行了探讨。

Global Positioning System has been widely used in forestry,but how to make a work plan suitable for the certain circumstances is still a problem to deal with.This paper introduced the experiment we carried out by using different GPS measuring modes in Yong An,Fujian.Comparing and evaluating the accuracies of different measuring modes,we present a solution for the lack of base station in the working area when measuring by differential GPS mode.Also in this paper,we made discussions on the GPS measuring modes for different forestry applications.
