Land subsidence rate analysis of Jakarta Metropolitan Region based on D-InSAR processing of Sentinel data C-Band frequency Land subsidence in Jakarta has been reported by many studies using various geodetic techniques. High exploitation of groundwater is the main factor of increasing land subsidence ra...
The article discusses an algorithm for processing complex SLC images of marine targets obtained at the output of Sentinel -1. The detection of maritime targets is based on AIS data and SLC targets chips export with ESA SNAP. The processing is done in MATLAB with ship detection and evaluation ...
InSAR time series analysis has become a major tool for nationwide land deformation monitoring. Sentinel-1 SAR data have enabled us to measure and monitor ground deformation globally with high accuracy and resolution through InSAR time series analysis, due to its constant and frequent global coverage ...
However, the entire mission was primarily designed for differential radar interferometry (DInSAR; Figure 1c) to measure surface deformations between two or more acquisitions, which imposes limits upon its capabilities to derive DEMs [39,40]. Accordingly, studies on the derivation of absolute ...
(LOS). Even considering the first velocity maps obtained using Sentinel-1 data only (Fig.1), standard deviation values of the average displacement rates (estimateda posteriorifrom the data) were all below 2.1 mm/year. With more than 900,000 points for each geometry of acquisition (and a...
Earthquakes and heavy rainfalls are the two leading causes of landslides around the world. Since they often occur across large areas, landslide detection requires rapid and reliable automatic detection approaches. Currently, deep learning (DL) approaches
In this work a PSI technique has been used for the longitudinal displacement monitoring of a railway bridge. Twenty-nine ascending C-band Sentinel-1A images have been analysed. A total of 1828 PS points have been selected and used for the PSI time series analysis. The estimated longitudinal ...

In comparison, northward, the displacement field is more diffuse for ~50 km along the PSN fault section, showing that the rupture may not reached the surface there with the same amplitude. We observe a total faulting length of ~140 km, which is consistent with previous studies9. The E...
