HIGH RESOLUTION SAR IMAGING EMPLOYING GEOMETRIC FEATURES FOR EXTRACTING SEISMIC DAMAGE OF BUILDINGS
SAR Imaging Geometry Feature Building Seismic Damage Extraction
2018/5/11
Synthetic Aperture Radar (SAR) image is relatively easy to acquire but difficult for interpretation. This paper probes how to identify seismic damage of building using geometric features of SAR. The S...

Landmark Extraction Geometric Features Crevice Horizon Segmentation Voronoi Diagram
2018/5/16
Landmark plays an important role in spatial cognition and spatial knowledge organization. Significance measuring model is the main method of landmark extraction. It is difficult to take account of the...
GLOBAL REGISTRATION OF KINECT POINT CLOUDS USING AUGMENTED EXTENDED INFORMATION FILTER AND MULTIPLE FEATURES
Global registration Kinect Augmented extended Information filter Point cloud fitting Indoor mapping
2016/10/14
Because the Infra-Red (IR) Kinect sensor only provides accurate depths up to 5 m for a limited field of view (60°), the problem of registration error accumulation becomes inevitable in indoor ma...
GEOLOGICAL FEATURES MAPPING USING PALSAR-2 DATA IN KELANTAN RIVER BASIN, PENINSULAR MALAYSIA
PALSAR-2 Geological features mapping Kelantan River basin Peninsular Malaysia
2016/10/14
In this study, the recently launched Phased Array type L-band Synthetic Aperture Radar-2 (PALSAR-2) onboard the Advanced Land Observing Satellite-2 (ALOS-2), remote sensing data were used to map geolo...
Assessment of deep electrical conductivity features of Northern Victoria Land (Antarctica) under other geophysical constraints
Magnetovariations electrical conductivity lithosphere
2015/9/28
The lithospheric and crustal structure of the Victoria Land continental block (Antarctica) has been studied by geological and geophysical surveys. Among them magnetovariational investigations (MV) hav...
Identification of tsunami deposits and liquefaction features in the Gargano area (Italy):paleoseismological implication
tsunami liquefaction Gargano 1627 earthquake
2015/9/16
The Gargano region (Southeastern Italy) was hit by a M = 6.8 earthquake and inundated by a subsequent tsunami in 1627. To better define the hazard in the region, we searched for evidence of this and p...
Power spectrum features of the near-Earth atmospheric electric field in Kamchatka
atmospheric quasi-static electric field atmospheric precipitation atmospheric waves
2015/9/14
Power spectrum of the diurnal variations of the quasi-electrostatic field Ez in the near-Earth atmosphere have been presented for the first time. The Ez power spectrum variations in the period of fine...
Time intermittency and spectral features of the geomagnetic field
nonlinear processes in geophysics geomagneticfield Earth's core fluid dynamics turbulence
2015/9/11
In the field of geomagnetism a number of studies have been devoted to the investigation of turbulence and intermittency in the outer core fluid motions. Here, in order to obtain information on such ph...
Mud volcanoes and methane seeps in Romania: main features and gas flux
methane mud volcanoes Romania
2015/9/2
Romania is one of the European countries with the most vigorous natural seepage of methane, uprising from
pressurised natural gas and petroleum reservoirs through deep faults. The largest seepage zon...
Analysis of a Permo-Triassic polarity transition in different absolute reconstructions of Pangaea,considering a model with features of the present Earth magnetic field
Permo-Triassic Pangaea absolute reconstruction Earth magnetic field polarity transition
2015/9/2
The main objective of this paper is to show that the distribution of transitional palaeomagnetic data recorded at 250 Ma are in agreement with simulated data that depend on the sampling site, using a ...
