Abstract:
The ground deformation problem caused by excessive exploitation of underground resources is very prominent in our country. Nowadays, InSAR technology has become an important tool for monitoring ground deformation. In this paper, we process regular hexagonal resampling for InSAR ground subsidence data, use the cumulative amount of risk measurement points as the clustering index, and use the DBSCAN algorithm to realize the risk area division.DBSCAN clustering based on regular hexagonal resampling is not restricted, and the parameters of the DBSCAN algorithm are difficult to choose, both with high flexibility. This experiment compares the speed of presentation with the effect of partitioning, and the results show that our method of region division is more intuitive. The results can be displayed within millisecond response, and the presentation speed is 1297.5 times faster than direct on-page plotting. Our method has a high practical application value for InSAR geological subsidence data.
