Images of a selected geographic region are obtained using remote sensing apparatus and are processed to determine characteristic spectral reflectance patterns associated with different ground covers and soil types in the region. The image processing means compares the spectral reflectance patterns to...http://www.google.es/patents/US5323317?utm_source=gb-gplus-sharePatente US5323317 - Method and apparatus for determining runoff using remote geographic sensing
