How to accurately determine the mechanical parameters of rockfill is one of the key issues of concrete-face rockfill dams. Parameter back-analysis using internal or external monitoring data has been proven to be an efficient way to solve this problem. However, traditional internal or external monitoring methods have limitations in efficiency and long-term monitoring. In this paper, the displace...

InSAR (space-borne Synthetic Aperture Radar Interferometry) data has revealed to be useful for surveying landslides and permafrost creeping features (e.g. rock glaciers) as it permits a time-lapse quantification of topography changes at mm to cm resolution over alpine areas where dense vegetation is no longer present. The capability of InSAR for detecting both the location of moving zones and t...

In this paper, an original approach for analyzing Interferometric Synthetic Aperture Radar (InSAR) time series is presented and applied to the monitoring of creep along a major active fault. InSAR data are computed from satellite acquisitions and allow ground deformations occurring between different dates to be measured with high precision over large areas. However, measurement precision remain...

Monitoring the subsidence at different periods in high underground water level coal mine areas can provide a data basis for land reclamation. For purpose of monitoring I working face located Guotun Coal Mine, 22 Sentinel-1 images were processed by using differential interferometric synthetic aperture radar (D-InSAR). After dividing periods, characteristics and accuracy explored. The results sho...

Atmospheric water vapour effects represent a major limitation of repeat-pass Interferometric SAR (InSAR) techniques including InSAR time series approaches (e.g. permanent scatterers (PS) and small baseline subset (SBAS)). In this paper, it is demonstrated that atmospheric water vapour effects greater than 4 cm can be observed even in desert regions (e.g. Southern California) and the use of MERI...

Zonguldak Hardcoal Basin is the largest bituminous coal region in Turkey where extensive underground mining activity exists. Because of this activity subsidence effects have been experienced in different locations of the city. In this study, surface deformations caused by the subsidence have been observed by D-InSAR technique using C-Band RADARSAT data. InSAR data process of 16 RADARSAT images ...

Interferometric synthetic aperture radar (InSAR) time series methods estimate the spatiotemporal evolution of surface deformation by incorporating information from multiple SAR interferograms. While various models have been developed to describe the interferometric phase and correlation statistics in individual interferograms, efforts to model the generalized covariance matrix that is directly ...

Using Sentinel-1A data in 2021, the displacement of Tomur Glacier radar line sight is obtained by repeated orbit differential interferometry. By introducing ice flow factor and combining glacier slope, vertical deformation extracted as surface elevation change. The results study found that overall average annual change decreased -14.03m, with an decrease -0.26 . reliability model was verified, ...

BACKGROUND REDD+ implementation requires establishment of a system for measuring, reporting and verification (MRV) of forest carbon changes. A challenge for MRV is the lack of satellite based methods that can track not only deforestation, but also degradation and forest growth, as well as a lack of historical data that can serve as a basis for a reference emission level. Working in a miombo woo...

During the last two decades synthetic aperture radar (SAR) and interferometric synthetic aperture radar (InSAR) have become important tools for airborne and satellite remote sensing. SAR delivers a high resolution image of the radar backscatter and by means of InSAR a second image from almost the same orbit is combined with the first one to provide the relative phase difference and stability/co...
