Abstract
Professor LI De-Ren is a wel-known international scientist specializing in the ifelds of photogrammetry and remote sensing, an academician of the Chinese Academy of Sciences and Chinese Academy of Engineering, and a director of the scientiifc committee of the State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing at Wuhan University. Professor Li gave this exclusive interview to the Shanghai Land&Resources journal on the afternoon of 26 July 2013. During the interview, Professor Li detailed the main components of the Dragon research program run by the Chinese Ministry of Science and Technology in cooperation with the European Space Agency. He also summarized the results already achieved, and explained recent technological progress in satel ite remote sensing monitoring and its application to resource management and environmental surveying. In view of ongoing issues related to urban land subsidence, he pointed out that monitoring accuracy wil be improved by the use of short wavelength double-antenna radar together with the polarization approach and differential interferometric synthetic aperture radar (InSAR) and permanent scatterer interference technology. Professor Li also discussed the increased use of ifber optic sensors for deformation monitoring during major projects, and the application of precision measuring processes. Furthermore, he suggested that technologies such as geodesic leveling, satellite remote sensing observations, and optical ifber sensor technology, if further developed so that they can be used col aboratively, would beneift both research and management of land and resources.关键词
