A MATCHING METHOD TO REDUCE THE INFLUENCE OF SAR GEOMETRIC DEFORMATION
SAR image image matching SURF SNCC geometrical deformations
2018/5/14
There are large geometrical deformations in SAR image, including foreshortening, layover, shade，which leads to SAR Image matching with low accuracy. Especially in complex terrain area, the control poi...
PRECURSORY SLOPE DEFORMATION AROUND LANDSLIDE AREA DETECTED BY INSAR THROUGHOUT JAPAN
InSAR landslide precursory slope deformation field survey
2016/7/5
Interferometric Synthetic Aperture Radar (InSAR) technique is able to detect a slope deformation around landslide (e.g., Singhroy et al., 2004; Une et al., 2008; Riedel and Walther, 2008; Sato et al.,...
ANALYSING POST-SEISMIC DEFORMATION OF IZMIT EARTHQUAKE WITH INSAR,GNSS AND COULOMB STRESS MODELLING
InSAR GNSS Coulomb stress changes North Anatolian Fault (NAF) Izmit earthquake deformation co-seismic
2016/7/4
On August 17th 1999, a Mw 7.4 earthquake struck the city of Izmit in the north-west of Turkey. This event was one of the most devastating earthquakes of the twentieth century. The epicentre of the Izm...
Deformation measurements at historical buildings with terrestrial laserscanners
Deformation Monitoring Terrestrial Laserscanning Cultural Heritage Documentation
2015/8/24
With the classical deformation measurement the objects are modeled by a number of measurement points which are distributed according to the deformation symmetrically as a grid or attached at selected ...
Deformation analysis of a bored tunnel by means of terrestrial laserscanning
Terrestrial laser scanning point cloud modeling tunnel deformation detection
2015/8/24
A procedure is developed, implemented and tested to detect deformations in a bored tunnel. Deformations can occur after construction of the tunnel is nished, i.e. between two measurement epochs, but a...
MEASUREMENT OF GROUND DEFORMATION INDUCED BY LIQUEFACTION AND FAULTING IN THE 1999 KOCAELI EARTHQUAKE AREA
Earthquakes Soil Photogrammetry Measurement Vector
2015/7/29
Turkey is one of the most seismically active countries in the world and most of her damaging earthquakes are of inland-type. These
earthquakes mostly result in permanent ground deformation as a cons...
Three Dimensional Deformation of Mining Area Detection by InSAR and Probability Integral Model
D-InSAR deformation monitoring probability integral method genetic algorithm land subsidence
2015/7/27
A new solution algorithm that combined D-InSAR and probability integral method was proposed to generate the three dimensional deformation in mining area. The details are as follows: according to the g...
AIRBORNE REPEAT PASS INTERFEROMETRY FOR DEFORMATION MEASUREMENTS
SAR Airborne Interferometry RPI Deformation Dike
2015/1/6
In ground engineering the need for deformation measurements is urgent. SAR interferometry can be used to measure small (sub-wavelength) deformations. An experiment to investigate this for dike deforma...
A satellite geodetic survey of largescale deformation of volcanic centres in the central Andes
A satellite geodetic survey large scale deformation volcanic centres in the central Andes
2014/4/9
Surface deformation in volcanic areas usually indicates movement of magma or hydrothermal fluids at depth. Stratovolcanoes tend to exhibit a complex relationship between deformation and eruptive behav...
