Stability monitoring based on Copernicus Sentinel-1 data
Stability monitoring is based on the evaluation and interpretation of the results of the displacement detection analysis. The automatic displacement detection analysis serves to monitor linear displacements of surface constructions using Synthetic Aperture Radar (SAR) images from Sentinel-1 mission. These displacements can be triggered by various processes (ground subsidence, underground mining, engineering works etc.). Long temporal series of satellite SAR images are analysed by custom implementation of Persistent Scatterers (PS) Interferometric SAR (InSAR) technique based on existing open source software (OST, SNAP). The whole Stability Monitor solution uses many open source components (Kubernetes, Docker, PostgreSQL/PostGIS, QGIS, GDAL etc.) and was developed within the ESA PropTech Kick-Start activity in 2021.
