A planning of large-scale PV system installed in a desert has been studied. This study has defined the conditions of estimation for suitable land in order to set up large-scale photovoltaic with remote sensing. Basis requirements for the land selection of PV systems are considered that the land surface should be flat and rigid and should not move like sand dune, mountain and river basin are also excluded. Authors show the identified examples of a flat ground, a sand dune and mountain by the combination of types of processed images, i.e. the image which is presumed as conglomerate desert, the image which is presumed as desert steppe, and the image which is extracted as an edge line by using various filters. So far, we could indicate that a detail classification algorithm for right land is developed. It is concluded that this proposed method can provide sufficient information for the planning of PV system installations.
