| Abstract: | The paper discusses quantitatively effects of terrain relief and geographic location of pixels on direct solar radiation and change of remotely sensed value caused by such effects. Then,formulas for computation of direct solor radiation on pixels and correction of direct radiation component of remotely sensed data are established. |
