Monitoring of landslides in Nainital, Uttarakhand, India: Validation of PS-InSAR results

2015 Joint Urban Remote Sensing Event (JURSE), 2015
This paper investigates the efficacy of Stanford Method for Persistent Scatterers (StaMPS) to monitor the critical landslides in Nainital township and adjoining areas of state of Uttarakhand, India which has problems due to inadequate drainage management system, seismically active Main Boundary Thrust (MBT) passing from the area, unwanted construction ...

Analyzing the topographic influence for the PS-INSAR processing in the Three Gorges region

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Persistent Scatterer Interferometry (PS-InSAR) is applied to derive displacement information with millimetric precision. Analyzing stable persistent scatterers from a large stack of SAR images,helps to overcome the geometrical and temporal decorrelation, which occur when using differential interferometry.

GEPATAR: A geotechnical based PS-InSAR toolbox for architectural conservation in Belgium

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
Ground displacements that cause structural damage to heritage buildings are precipitating cultural and economic value losses. The GEPATAR project (GEotechnical and Patrimonial Archives Toolbox for ARchitectural conservation in Belgium) aims creating an online interactive geoinformation tool that allows the user to view and to be informed about the ...

A study of PS-InSAR method for small area urban land subsidence

2010 18th International Conference on Geoinformatics, 2010
Persistent Scatterers for SAR Interferometry (PS-InSAR) tecnique allows monitoring the temporal evolution of a deformation phenomenon at millimeter level, via the generation of mean deformation velocity maps and displacement time series from a data set of acquired SAR images.

A PS- InSAR Sequential Processing Method Based on Network Reconstruction

2018 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2018
Permanent scatterers in SAR interferometry (PS-InSAR) is used in the long time monitoring of deformation on the earth's surface. However, the traditional PS-InSAR is a method of batch handing to accomplish detecting and networking the permanent scatterers (PS) and parameter calculation, which greatly reduce the processing efficiency.

Multicriteria analysis for landslide inventory mapping using PS-InSAR

2019 IEEE Recent Advances in Geoscience and Remote Sensing : Technologies, Standards and Applications (TENGARSS), 2019
In this research work, a multicriteria analysis is performed for the preparation of landslide inventory maps in Uttarakhand, India primarily using PS-InSAR approach. A pre-existing landslide inventory map, initially prepared by Geological Survey of India (GSI) is validated through processing of 10 Sentinel-1A and 15 Envisat ASAR images corresponding to

Integrating PS-InSAR and SBAS-InSAR for mining surface settlement monitoring

Journal of Mines, Metals and Fuels, 2022
Based on 38 Sentinel-1A images, this paper imports GCP points generated by PS-InSAR into SBAS-InSAR, instead of manually selected GCP points, extracts surface deformation in the study area, and compares and analyzes with traditional GPS monitoring data.

Data Assimilation of PS-InSAR Movement Measurements Applied to the Bergermeer Gas Field

Proceedings, 2013
This paper reports a study on the use of satellite radar data to constrain the subsurface model parameters of the Bergermeer gas field. Using PSI (Persistent Scatterer InSAR) technology, ascending and descending data were applied in line-of-sight geometry, i.e., without first unravelling the horizontal and vertical components of the signal.
