Application status of middle and high resolution remote sensing images in agriculture

In order to better understand the present application and research status of middle and high resolution remote sensing images in agriculture, an overview and a prospect of which are provided in this paper. The application are mainly described in eight aspects: vegetation type recognizing and classification, crops area estimation and monitoring, crops nutrient and water condition monitoring, crops leaf area and biomass and chlorophyll content monitoring, pest and disease monitoring and prediction, agriculture natural disaster monitoring, agriculture land resource dynamic variation and monitoring, crops yield prediction. The author also points out that the prospect of the middle and high resolution remote sensing images in agriculture are in six aspects as follows: to make the agricultural work more precise, to integrate various technologies and methods, to unify database of agriculture remote sensing images, to make up the imperfection of current remote sensing technology, to improve the standard vegetable spectral database and to enhance the vegetable interpretation system. The paper provides a reference for the remote sensing application and research in agriculture.
