Detection and Monitoring of Land Subsidence By the PSInSAR Method

Abstract

The InSAR technique is a powerful tool for monitoring land subsidence, which has the potential to provide millimeter-accurate displacement determinations. By using the free Sentinel-1 images, which have a very large spatial coverage and a high frequency of repeated passes over the same area, the InSAR technique can offer good spatial and temporal displacement analysis with high accuracy. Considering the existence of a significant number of free research software, and the need to engage a smaller number of professional staff, this technique is significantly more financially favorable than other methods.
