摘要

Because of the population increment in the world, there is a growing need for micro-level planning and particularly the demand for crop insurance which increases the need for field level yield statistics. Therefore, from economic point of view, accurate and fast crop yield estimation is very important in national and regional scale. There are two methods for crop yield estimation viz., (1) Conventional methods and (2) Methods based on remote sensing data. Conventional methods are often complicated, costly, time consuming and they cannot be run in large scales. Therefore, it is necessary to use cheaper/faster methods for crop yield estimation. Remote sensing data have the potential and the capacity to provide spatial information at global scale; of features and phenomena on earth on an almost real-time basis. They have the potential not only in identifying crop classes but also of estimating crop yield. In this paper first, conventional methods and their disadvantages are reviewed. Then crop yield estimation methods based on remote sensing data were compared to each other and their advantages and disadvantages were discussed.
