Wuhan Surface Subsidence Analysis in 2015–2016 Based on Sentinel-1A Data by SBAS-InSAR
The Terrain Observation with Progressive Scans (TOPS) acquisition mode of Sentinel-1A provides a wide coverage per acquisition and features a repeat cycle of 12 days, making this acquisition mode attractive for surface subsidence monitoring.

Monitoring of Surface Subsidence of the Mining Area Based on SBAS [PDF]
This paper has collected 7 scenes of L band PALSAR sensor radar data of a mine in FengCheng city, jiangxi province, using the Small-baseline Subset (SBAS) method to invert the surface subsidence of the mine. Baselines of interference less than 800m has been chosen to constitute short baseline differential interference atlas, using pixels whose average ...

SURFACE SUBSIDENCE MONITORING IN GANZHOU AREA BASED ON SBAS-INSAR
Abstract. In this paper, we first obtained the temporal-spatial changes of surface subsidence in Ganzhou area based on SBAS-InSAR technology using 24 scenes Sentine-1A images covering the Ganzhou area from 2018 to 2020. Then we studied the surface subsidence characteristics in the study area.

Control of surface subsidence based on building deformation monitoring data [PDF]
This paper presents an approach to the estimation of ground surface distortion based on the data from the online deformation monitoring systems mounted on the foundations of the group of buildings located in the area of ground instability. The local monitoring systems provide control of building foundation settlements using the hydrostatic level ...

Applicability of two grey models in earth-surface subsidence prediction of mining area
Existing dynamic single-point subsidence prediction methods of mining area earth-surface are mainly based on traditional leveling measurement data, which have single monitoring mode, high cost and easily destroyed observation points, and cannot guarantee
