GPS技术在农业遥感中的应用

Application of GPS Technology in Agricultural Remote Sensing

全球定位系统(简称GPS)是以卫星为基础的无线电卫星导航定位系统,它具有全天候、全球性、实时性等精密三维导航与定位功能。因此,将GPS这一先进的测量技术广泛应用在农业遥感工作中,能够快速、准确、高效地提供各类地物的精确坐标,从而为农业遥感工作中图像校正、解译标志建立、规划路线导航、地面样方的布设与验证等工作提供必要的技术支持,成为农业遥感监测的有力工具。

Global Positioning System（GPS）is a satellite based radio navigation and positioning satellite system,which has all-weather,global,real-time three-dimensional,such as precision navigation and positioning capabilities.Therefore,GPS measurements of the advanced remote sensing technology widely used in agricultural work could provide various types of surface features of the exact coordinates fast,accurate and efficient,so as to work in agricultural remote sensing image correction,interpretation signs,with the planned route navigation,the layout of the ground plots and verification and other work to provide the necessary technical support to become agricultural remote sensing a powerful tool for monitoring the test.
