Monitoring land subsidence in Wuhan city based on Sentinel-1

doi:10.13474/j.cnki.11-2246.2021.0273

Abstract

Abstract: Due to the construction of underground space planning projects in major cities, there are different degrees of land subsidence geological disasters. In this paper, sentinel-1A data from June 2020 to March 2021 in the main urban area of Wuhan city is selected as the data source, and the small baseline set technology is used to monitor the surface deformation in this area. The results can provide basic support for the prevention and control of land subsidence and the occurrence and development of disaster chain.

Key words: ground subsidence, Sentinel-1A, small baseline subset, disaster, InSAR
