Remote sensing is an important method for rapidly obtaining farmland information. Once meteorological disaster occurs, using the remote sensing technology to extract disaster area of crops and monitor disaster level has great significance for evaluating disasters and making a timely remedy. This paper elaborated the importance of monitoring agro-meteorological disasters using remote sensing in current special historical period, overviewed remote sensing methods both at home and abroad, analyzed existing problems, made clear major problems to be solved in monitoring agro-meteorological disasters using remote sensing, and discussed the development prospect of the remote sensing technology.
