Deskripsi

<p>Subsidence can now be routinely mapped on a national scale thanks to ESA's Sentinel-1 sensors and advanced scalable SqueeSAR<sup>®</sup> processing. In order to be integrated into existing monitoring programmes, the SqueeSAR<sup>®</sup> datasets can be calibrated with GNSS measurements. The dense spatial coverage of SqueeSAR<sup>®</sup> deformation maps captures local deformation phenomena, and with appropriate calibration, can advance the understanding of regional deformation trends. The regular and reliable SAR image acquisitions by Sentinel-1, as well as significant improvements in the scalability of SqueeSAR<sup>®</sup> processing allow regular updates of deformation maps on a national scale. Filtering the large amount of data for relevant information is achieved by using an algorithm to detect changes in displacement trends.</p>
