BEIJING, Nov. 16 (Xinhuanet) -- China will remeasure the length of the Great Wall built in Ming Dynasty (1368-1644), with the help of aeronautic remote sensing technology, said Zhang Ji, deputy secretary-general of China Great Wall Institute here Wednesday.

Zhang said a program on comprehensively surveying the Great Wall with remote sensing technology was made and approved as feasible by experts.

The program will provide an accurate length of the Great Wall, which was built by Chinese first emperor Qinshihuang, and rebuilt and renovated in Ming Dynasty.

The current measure of the Great Wall, which is 7300 kilometers, is likely not a very accurate one due to the relatively backward measuring equipment and methods in the past, said Zhang.

He said the program will not only offer the actual length of the world wonder, but can also provide pictures of its overall layout, which is significant to the preservation of this cultural relic.
