Abstract:
    This invention involves a method for obtaining the scattering / direct ratio of natural light on the ground via the remote sensing digital images and digital topographic maps. The steps are: Firstly, it inputs the remote sensing digital images and the corresponding digital topographic maps to search the shadow and calculate the parameters. Then, it calculates the natural light scattering / direct ratio of the shadow on the ground. Then, it calculates the natural light scattering / direct ratio of all the shadow on the ground. Then, it interpolating-calculates the natural light scattering / direct ratio of the points without shadow on the ground. Finally, it outputs the natural light scattering / direct ratio corresponding to the ground.
