Chinese Academy of Engineering, Xian-Lin Liu, today a guest Renmin interview, said that survey and mapping work in the course of building the lunar base as "vanguard" of Chinese scientists to use "Chang'e One" satellite orbiting the moon to detect one year of scientific data to map out At present the international plane and the terrain in the highest resolution, the data most accurate three-dimensional digital terrain map full moon, the moon for the future design of the process has an important use.

Xian-Lin Liu said the first lunar base construction site, to where the plans for the building, surrounded by a very fine landscape requires mapping out in advance, so mapping such as the "vanguard." "Chang'e One" is a beginning of the Moon Review, the second step "Chang'e II," and also set it to police. Xian-Lin Liu said that the full moon, three-dimensional digital terrain map can give scientists a lot of interesting basic data: not only can be used on the moon on a landscape, the lunar surface topography to study the structure of the landscape to conduct research on geological research, as well as the The mechanism of the formation of the moon to provide a basic data research; can also prepare for future moon landing, in which various parts, how landing, landers how to design, landing process, security, and the lunar landing vehicle after walking, all is inseparable from the topographic maps.


Xian-Lin Liu also mentioned that the mapping technology in the course of the moon will be used, "such as the moon landing and began to reverse when the ignition is very soft landing to the moon above, go, how to master this opportunity, we must measure the height, The high degree of laser measurements, is also the mapping work.
