Paper Abstract

Because of natural contribution and man-made disturb, segments of Ming Great Wall in NingXia province and Shaanxi province were mostly destroyed, even more some of them were disappeared from the surface of earth and buried by sand. It is not an easy thing to detect the Great Wall by field survey since it is quite long, and fieldwork needs a lot of human and financial resources. It is not an easy thing to detect the Great Wall by field survey since it is quite long and fieldwork needs a lot of human and financial resources to detect the Great Wall by field survey since it is quite long, and fieldwork needs a lot of human and financial resources. In this paper, remote sensing technology was used such as SAR and optical remote sensing, pixel image fusion between SAR image and optical image was achieved, and then skeleton method was tested to automatically generate the Ming Great Wall based on the fusion image and the test got satisfied results. Finally, the spatial location information of the Ming Great Wall was produced successfully.
