Earthquake-Induced Building Damage Detection with Post-Event Sub-Meter VHR TerraSAR-X Staring Spotlight Imagery
Compared with optical sensors, Synthetic Aperture Radar (SAR) can provide important damage information due to its ability to map areas affected by earthquakes independently from weather conditions and solar illumination. In 2013, a new TerraSAR-X mode named staring spotlight (ST), whose azimuth resolution was improved to 0.24 m, was introduced for various applications. This data source made it ...
متن کاملForest Variable Estimation Using Radargrammetric Processing of TerraSAR-X Images in Boreal Forests
The last decade has seen launches of radar satellite missions operating in X-band with the sensors acquiring images with spatial resolutions on the order of 1 m. This study uses digital surface models (DSMs) extracted from stereo synthetic aperture radar images and a reference airborne laser scanning digital terrain model to calculate the above-ground biomass and tree height. The resulting valu...
متن کاملDetection of damage to building side-walls in the 2011 Tohoku, Japan earthquake using high-resolution TerraSAR-X images [8892-37]
Building damage such as to side-walls or mid-story collapse is often overlooked in vertical optical images. Hence, in order to observe such building damage modes, high-resolution SAR images are introduced considering the side-looking nature of SAR. In the 2011 Tohoku, Japan, earthquake, a large number of buildings were collapsed or severely damaged due to repeated tsunamis. One of the important...
متن کاملMultitemporal Observations of Sugarcane by TerraSAR-X Images
The objective of this study is to investigate the potential of TerraSAR-X (X-band) in monitoring sugarcane growth on Reunion Island (located in the Indian Ocean). Multi-temporal TerraSAR data acquired at various incidence angles (17°, 31°, 37°, 47°, 58°) and polarizations (HH, HV, VV) were analyzed in order to study the behaviour of SAR (synthetic aperture radar) signal as a function of sugarca...
متن کاملMapping Urban Area Extents with Terrasar-x Single- Polarization Images
I – Introduction From the more structured urban areas in Europe and USA to the more chaotic Chinese, Asia’s and South America’s ones, from megalopolis to small and sparse settlements, the role of human settlements is becoming more and more important in land management, regional policy definition, and global modeling of environmental phenomena. The need for increased and more and more specific d...
