Integrated Radar Interferometry for Ground Subsidence Monitoring
This paper reports the progress of the ongoing ESA CAT-1 project (ID 1078). Radar interferometry (InSAR) has been used together with GIS (Geographic Information System) technique to monitor ground subsidence due to underground mining in a test site around the Appin township, southwest of Sydney, Australia. Various digital elevation models (DEMs) are assessed using elevation profiles from ground...
متن کاملAutomated classification of Persistent Scatterers Interferometry time series
We present a new method for the automatic classification of Persistent Scatters Interferometry (PSI) time series based on a conditional sequence of statistical tests. Time series are classified into distinctive predefined target trends, such as uncorrelated, linear, quadratic, bilinear and discontinuous, that describe different styles of ground deformation. Our automatic analysis overcomes limi...
متن کاملRadar Interferometry for Ground Subsidence Monitoring Using Alos Palsar Data
This paper describes the results using data from ALOS and ENVISAT satellites for the purpose of subsidence monitoring over underground coal mine sites in the state of New South Wales, Australia, using the differential interferometric synthetic aperture radar (DInSAR) technique. The quality of the mine subsidence monitoring results is mainly constrained by the noise due to the spatial and tempor...
متن کاملUltrashort-baseline Persistent Scatterer Radar Interferometry for Subsidence Detection
This paper presents an improved approach of multi-temporal interferometric synthetic aperture radar (InSAR) for detecting land subsidence phenomena by using time series of high resolution SAR images. Our algorithm extends the capability of the temporarily coherent point (TCP) InSAR technique proposed previously to detect subsidence even in the case of a small number of SAR images available for ...
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...
