| Abstract | ||
| In this historical survey, we have reviewed researches of shadow phenomenon in satellite images since the beginning of the need for treatment and interpretation in remote sensing. Because remote sensing enters into many applications and is shared with many sciences, studies on the phenomenon of shadows have been conducted with in different ways. In this review, we attempted to link the evolution of remote sensing techniques with growing resolution of space images as research progresses in the treatment of shadows, because the evolution of space sensor abilities sure increases the options for the interpreter and processor of the satellite image in remote sensing and other purposes. There were also problems that appeared only with the emergence of high-resolution satellite images (0.6 meters) such as the problem of the semi-shadow region. Some researches included some weaknesses and limitations that could not be comprehensive for all satellite images, for all regions of the earth, or for all target shadows. | ||
