Abstract :
Usually a vegetated area pixel is composed of the basic components, soil, leaf with different proportions, while soil and leaf have different water content. There are lots of canopy models to describe the mechanism with which these component spectra compose the canopy spectrum. For practicability, a simplified model is suggested to calculate the surface vegetation coverage, and water contents of leaf and soil from pixel reflectance, such as multi-spectral remote sensing data. Experiment results show that the accuracy of this method can satisfy the application´s request.
