Abstract : It has been generally accepted that the remotely sensed MSS data are the most efficient way immediately to obtain the information of a ground surface. It is also an important fact that they have different count levels in spite of quite same objects because of the angular effects caused by the rough surface in the optical sense. There is no good correction method except by the ground truth data at present. A new reflection model (ref.5) for the corn fields, especially paddy fields, has been proposed on the recognition that there is a need to develope some approaches in order to obtain the ground truth data without expensive and time consuming ground truth observation. The model developed has an advantage that the situation very close to the real paddy fields can be simulated by manipulating some parameters and the data on the ground truth can be gathered under various conditions.
