【Abstract】 This paper analyzes three methods for extraction using remote sensing:experience model method,vegetation index method and mixxed\|image analysis method, and advances the model based on vegetation fraction extraction using middle differentiate frank sat image combining high differentiate frank sat image. It is proved that this model is simple and practical. 更多还原
