Problems and countermeasures of 3S technologies application in precision agriculture

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.
