Application of DInSAR and GIS for Underground Mine Subsidence Monitoring
DInSAR GIS Mine subsidence ERS Envisat Tangshan
2015/11/20
This research used both ERS and Envisat images to investigate the feasibility of differential radar interferometry (DInSAR) for mine subsidence monitoring in Tang Shan, Hebei Province, China. DInSAR r...
PRODUCTS DERIVED FROM AN ADVANCED DINSAR-GIS APPLICATION FOR RISK MANAGEMENT
SAR InSAR DInSAR
2015/8/31
This paper presents an advanced DInSAR-GIS technique developed by the Cartographic Institute of Catalonia (ICC) for the
generation of precise terrain deformation maps using data acquired by satellite...
Enhancing DInSAR capabilities for landslide monitoring by applying GIS-based multicriteria filtering analysis
Landslide monitoring DInSAR GIS multicriteria analysis
2015/5/7
Landslide detection and monitoring remain difficult with conventional differential radar interferometry (DInSAR) because most pixels of radar interferograms around landslides are affected by differe...
A digital elevation model (DEM) is a 3D visualization of a terrain surface. It can be used in various analytical studies such as topographic feature extraction, hydrology, geomorphology and landslides...

2014/12/4
The research objectives of the Aquistore CO2 storage project are to design, adapt, and test non-seismic monitoring methods for measurement, and verification of CO2 storage, and to integrate data to de...
Analysis of deformation patterns through advanced DINSAR techniques in Istanbul megacity
Differential SAR Interferometry Small BAseline Subset TerraSAR-X Deformation Monitoring
2014/9/29
As result of the Turkey’s economic growth and heavy migration processes from rural areas, Istanbul has experienced a high urbanization rate, with severe impacts on the environment in terms of natural ...
本文以开采沉陷基本理论为依据，建立了DInSAR和GPS联合加密观测工作面推进距离模型，得出了工作面推进过程中的两次加密时间，即地表变形点下沉速度的剧增点和剧减点监测时刻，从而提高了DInSAR技术监测地表动态变形的有效性。最后以澳大利亚West Cliff煤矿长壁工作面32开采期间获取的DInSAR和GPS数据进行了实例分析。
