Italy uses Sentinel-1 satellite data to monitor sinking ground surfaces

Ground deformation map of Pistoia in Tuscany. Using data acquired between 2014 and 2019 from the Copernicus Sentinel-1 mission, the map shows subsidence in red and uplift in blue. Image: ESA/TRE ALTAMIRA.

The lowering or sinking of the ground’s surface, referred to as land subsidence, can cause serious damage to infrastructure and private property, and in turn, have an adverse impact on communities, individuals, and the economy.

This webinar aims to show how to use SAR interferometry (InSAR) to identify and map land subsidence using the ESA SNAP Sentinel-1 Toolbox. It demonstrate how to access the RUS Service and how to download, process, analyze and visualize the free data acquired by the Copernicus satellites.

Data application of the month: Land deformation mapping using DInSAR

Land subsidence in California due to the withdrawal of groundwater. Image: USGS.

Various phenomena and processes such as earthquakes, geological phenomena, ice motion, changes of groundwater flow by aquifer overexploitation and hydrocarbon extraction have as a consequence the deformation of the Earth's surface, which modifies its physical parameters.

CATHALAC: Satellite-aided analysis of land subsidence

UN-SPIDER’s Regional Support Office CATHALAC prepared a preliminary analysis of the effects of land subsidence in Mixco, Guatemala using space-based information. The analysis was prepared in the context of SERVIR and with the collaboration of Guatemala’s Ministry of the Environment (MARN), the National Protected Areas Council (CONAP), and UN-SPIDER.
