Chengdu is the fastest settlement where the largest is 1.4 cm in red is the deformation rate of the place, the Green strain rate is small, yellow is the strain rate in the middle of nowhere (Dujiangyan city) in Chengdu where the largest settlement the fastest is 1.4 cm years according to the objectives and tasks of the development of surveying and mapping "in 12th Five-Year in Sichuan province based development planning" the Sichuan Provincial Bureau of Surveying and mapping geographic information and work arrangements, by the Sichuan Province third surveying and Mapping Engineering Institute is responsible for key regional deformation monitoring project implementation, the third surveying and Mapping Engineering Institute of engineer sun Xiao Peng is the person in charge of the project. From 2013 to 2015, he has been involved in Chengdu, Mianyang, Leshan and 4 cities in the land subsidence monitoring work. Sun Xiaopeng introduced the key regional ground deformation monitoring work from the beginning of 2013, we mainly in high resolution radar image COSMO-SkyMed as the data source, the Permanent Scatterers interferometry radar (PS-InSAR) monitoring 4 city completed in Chengdu, Mianyang, the monitoring precision can reach millimeter. "We found that in these four cities, the land subsidence rate in Chengdu was the largest." Sun Xiaopeng told reporters.相关的主题文章:
