Abstract

3S technologies are the core technologies of precision agriculture. On the basis of deep analysis of the current 3S technologies application in precision agriculture, this thesis points out some problems about this application, mainly including incomplete agricultural remote sensing mode, low level of remote sensing interpretation, low standardization and sharing degree of remote sensing, lack of GIS basic data. It also puts forward some suggestions and countermeasures to solve these problems, including improving and expanding agriculture database, researching the mechanism of agricultural remote sensing image interpretation, enhancing standardization of remote sensing data, improving positioning accuracy of farmland operations, attaching importance to integration of new farm machinery and 3S technologies, and applying seamless integration of multi-source spatial data.

Highlights

  • Precision agriculture is the new trend in agricultural development in the world today

  • With the rapid development of spatial technology and information technology, the 3S technologies are widely used in modern agriculture, promoting the informatization of agricultural production

  • In China, the expensive and numerous images are not managed under unified rules, which leads to different coordinates, scattered storage and difficult application, resulting in extravagant wastage of resources[12]

Summary

Introduction

Precision agriculture is the new trend in agricultural development in the world today. It is a system supported by information technology based on spatial variation and used to implement a set of modern farming operative techniques as well as management in accordance with positioning, timing and quantifying[1]. Different temporal and spatial information about agricultural production is obtained. Precision agriculture brings agriculture into the era of data and information and turns to be the main agricultural production form of rationally using agricultural resources, increasing crop yields, reducing production cost and improving ecological environment. With the rapid development of spatial technology and information technology, the 3S technologies are widely used in modern agriculture, promoting the informatization of agricultural production. The precision agriculture, with the 3S technologies as the core, has drawn much attention
