BEIJING : China will soon embark on a multi-million dollar project to survey
and measure its iconic Great Wall.
Surveillance of the Beijing segment alone will cost US$1.25 million, and
teams will start the physically challenging task this month.
It is the only man-made structure that can be seen from space.
At some stretches, the Great Wall of China is even wide enough for four
horses to gallop.
And some believe the bricks used for the Wall are enough to build four grand
Former Chinese leader Chairman Mao even had a saying - "You're not a
courageous man until you've been to the Great Wall."

been a magnet for foreigners and locals alike.

Ms Li says: "We have climbed many sections of the Great Wall. I hope there
will be restoration work so that it will be even better."
Her hopes could be fulfilled soon, with the launch of a multi-million dollar
project to survey and measure all stretches of the Great Wall.
The project will not only confirm the actual length of the world wonder, but
also provide pictorial data of its overall layout, which is significant to the
preservation of the cultural relic.
Up to 10 teams from Beijing who have been training through winter are setting
It is a challenging and arduous task.
Mr Wang Yuwei, Chief of Beijing Cultural Heritage Protection Department,
says: "We will have to walk some days and rest in between. We are also limited
by the weather. There are no proper paths and some paths are covered with wild
grasses. So this year, we can only trek in the months of April and May, and
again from November to December."
On segments deemed too dangerous for humans to trek, Global Positioning
Satellite (GPS) will be used.
GPS is more precise than surveillance by humans, but it is a costly
technology that will be employed selectively.
A temporary order stipulates that areas within 500 metres of the Great Wall
are to be protected.
Mr Wang says: "The Beijing section of the Great Wall is more than 600
kilometres long but some parts have not been surveyed, for instance, these "mini
castles". We will not only have to trek along the Great Wall but also travel to
