The dataset includes cumulative surface subsidence (time1_time2.tif) and deformation rate (Lutan (August 2023 July 2024) deformation rate monitoring results. tif). The data time range is from August 2023 to July 2024, and the data space range is from 99.586 ° E to 99.855 ° E and from 29.923 ° N to 30.144 ° N.
The data is sourced from LT-1 SAR data and obtained from the Land and Resources Satellite Center.
The corresponding surface deformation rate and cumulative settlement are obtained through image registration, interferometric image pair combination, high coherence point selection, differential interferometry, filtering, phase unwrapping, low-frequency and high-frequency deformation calculation, and geographic coding operations.
The average standard deviation of deformation values at most monitoring points is in the millimeter range and follows a normal distribution. Through the internal consistency accuracy verification of the monitoring results, it indicates that the monitoring results are at the sub centimeter level and have high reliability.
