| Abstract: | This paper discusses the influence which topograghy,atmosphere and geographicplace have upon three branches(direction,diffusion and neighboring slope reflectance )ofsolar radiation on pixeles of satellite image,and the change of satellite remotely sensed da-ta is caused by it.The quantitative relation among ground radiation,topography,atmo-sphere and remotely sensed data are also studied, and base on it,the principles and meth-ods about ground radiation correction of satellite remote sensing digital image are dis-cussed.The satellite remote sensing data corrected by ground radiation can satisfy needsof study about remote sensing application base and groud radiation state. |
