| Abstract: | Professor LI De-Ren is a well-known international scientist specializing in the fields of photogFammetry and remote sensing, an academician of the Chinese Academy of Sciences and Chinese Academy of Engineenng, and a director of the scientific 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 $hanghaiLand ＆ Resourcesjoumal on the altemoon of 26 July 2013. Dunng 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 summanzed the results already achieved, and explained recent technological progress in satellite 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 will be improved by the use of short wavelength double-antenna radar together with the polanzation approach and differential interferometric synthetic aperture radar （InSAR） and permanent scatterer interference technology. Professor Li also discussed the increased use of fiber optic sensors for deformation monitoring dunng major projects, and the application of precision measuring processes. Furthermore, he suggested that technologies such as geodesic leveling, satellite remote sensing observations, and optical fiber sensor technology, if further developed so that they can be used cQUabQra0vely, would benefit both research and management of land and resources. |
