Satellite radar interferometry for mine subsidence monitoring
Australia is one of the world’s leading mineral resource extraction and exporting nations. Underground mining can cause ground surface displacement, which may in turn have serious impacts on the environment or man-built facilities. This paper describes the results of a study into the feasibility of surface subsidence (caused by underground coal mining) monitoring using differential interferomet...
متن کاملGround Subsidence Monitored by L-band Satellite Radar Interferometry
Ground subsidence can be caused by both natural and human-induced activities. In this paper, a radar remote sensing technique named Differential Interferometric SAR (D-InSAR) is introduced as means of monitoring the ground deformation caused by mining activities. D-InSAR and current geodetic technologies, such as GPS, are complementary in monitoring ground subsidence due to underground mining a...
متن کاملImaging Land Subsidence Induced by Groundwater Extraction in Beijing (China) Using Satellite Radar Interferometry
Beijing is one of the most water-stressed cities in the world. Due to over-exploitation of groundwater, the Beijing region has been suffering from land subsidence since 1935. In this study, the Small Baseline InSAR technique has been employed to process Envisat ASAR images acquired between 2003 and 2010 and TerraSAR-X stripmap images collected from 2010 to 2011 to investigate land subsidence in...
متن کاملThe Application of Satellite Radar Interferometry to the Study of Land Subsidence over Developed Aquifer Systems
This dissertation investigates the application of interferometric synthetic aperture radar (InSAR) to the measurement and interpretation of surface displacements over developed aquifer systems. Land subsidence over developed groundwater systems has been observed in a wide variety of hydrogeologic settings worldwide. The phenomenon can be explained with elastic and inelastic deformation of water...
متن کاملMonitoring Land Surface Subsidence Using Radar Interferometry: The Challenges
SUMMARY Subsidence of the land surface is defined as the vertical surface movement due to the removal of subsurface support. This paper presents the differential interferometric synthetic aperture radar (DInSAR) results derived from the data of various SAR satellites, such as ERS-1/2, Radarsat-1 and JERS-1, for subsidence monitoring. One of the limitations of selecting the suitable interferomet...
