Abstract

The Ming Great Wall in Ningxia and Shaanxi area was so considerably destroyed by natural and man

activities that a part of the wall disappeared from the Earth's surface and was buried by sand. Therefore, it is

very important to detect the spatial location and trend of the Ming Great Wall by remote sensing technology,

especially by combining the SAR method which can penetrate the Earth's surface and the optical remote sensing

method. The authors used pixel image fusion between SAR image and optical image which were HIS transform fusion

and PC transform fusion respectively. After comparing the fusion result between HIS and PC, the skeleton method

was used to extract the Ming Great Wall automatically based on the PC fusion image and thus acquired satisfactory

results. The spatial location of the Ming Great Wall was eventually detected.
