Interferometry Synthetic Aperture Radar (InSAR) Application for Flood Area Detection Observed by Sentinel 1A

2018 Progress in Electromagnetics Research Symposium (PIERS-Toyama), 2018
Almost every year, flood and landslide occur at Pangkalan Lima Puluh Kota district, West Sumatra, Indonesia. These not only destroyed the agricultural but also isolated the area. The area is essential for supporting transportation connection in the center of Sumatra.

Velocities field of mountain glacier obtained by synthetic aperture radar interferometry. comparison of insar and surveyed velocities

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
The Mer de Glace and Argentiegravere glaciers are located in the Mont Blanc region, French Alps. They are temperate glaciers and their velocity flow is about one hundred meters a year (~270 mm a day). This paper presents a use of synthetic-aperture radar (SAR) interferogram obtained from the two European Remote-Sensing satellites (ERS1-2) to measure ...

Application of Interferometry Synthetic Aperture Radar (InSAR) in the study of the subsidence of Mexico City and its relationship with the abatement of the static level of groundwater.

2023
Mexico City has suffered for many years from the phenomenon of land subsidence because the city is located within the limits of the old Lake Texcoco. The lithological materials that constitute the lake area are deposits, mainly clayey, of low consolidation, that compose the upper aquitard of the city, from which volumes of water have been extracted ...

Subsidence of Kolkata (Calcutta) City, India during the 1990s as observed from space by Differential Synthetic Aperture Radar Interferometry (D-InSAR) technique

Remote Sensing of Environment, 2006
Abstract In Kolkata City, India potential land subsidence, due to over-drafting of groundwater under confined condition, has been reported by a number of previous workers and by the local media. The presence of a thick surface clay layer with an average thickness of more than 40 m over the aquifer sand layer raises questions on the possibility and ...
