We propose using satellite remote sensing technology with a modified damage detection model based on the regression discriminant function for severe building damage ratios as a method to quickly estimate damaged areas due to tsunamis anywhere in the world. The model was developed using a data set from JERS-1/SAR images of the aftermath of the 1995 Kobe earthquake and its detailed ground-truth d...

We have been studying coand postseismic displacements from large earthquakes since mid-2006, using ALOS PALSAR images acquired before and after these events. Due to its wavelength, coherence is high even in heavily vegetated areas or steep ranges. We can estimate slip distribution of these earthquakes based on the observed interferograms using a nonlinear inversion scheme. So far, we could not ...

On October 29, 2008, magnitude 6.4 earthquake occurred in a area of western Pakistan. One of the Japanese earth observation satellite, Advanced Land Observing Satellite (ALOS), observed this area by all onboard sensors, AVNIR-2, PRISM, and PALSAR. By optical imagery, AVNIR-2 and PRISM imagery, huge landslide (rock slide) and landslide dam were confirmed by visual interpretation. And also this l...

Land surface deformation due to underground mining is always a concern to the local communities and environment. The underground coal mines at the study site in Northern China are located quite closely to each other. In order to ensure safe mining as well as to prevent illegal mining activities, differential radar interferometry (DInSAR) was introduced for monitoring mine subsidence. The spaceb...

Land surface deformation can be caused by underground mining activities. The maximum subsidence normally occurs directly above the location of the excavation of the coal seam. In the case where the longwall mining technique is applied, the magnitude and shape of the subsidence bowl are constrained by the longwall structure (pillar). This paper describes the use of satellite radar interferometry...

This paper discusses stem volume retrieval based on inversion of SAR data, and proposes a new robust inversion approach. The method used employs model fitting with an inverted semi-empirical boreal forest SAR model, and takes advantage of the multitemporal aspect in order to improve the stability and accuracy of stem volume estimation. The approach is demonstrated using multitemporal dual-pol S...

This paper describes the research plan to use ALOS / PALSAR data for Antarctic ice sheet analysis. The final goal of our study is to extract the precise ice sheet elevation and estimate accurate position of grounding line using ALOS / PALSAR data. The authors have been studying the grounding line and ice sheet topography from InSAR data, which mainly used ERS-1/2 tandem data. We plan to adopt t...

This brief presents a novel nonlinear adaptive line-of-sight (ALOS) guidance law for path following, compensating drift forces due to wind, waves, and ocean currents. The ALOS is proven have uniform semiglobal exponential stability (USGES) properties during straight-line following at constant speed. performs similar the classical integral (ILOS) ILOS laws when sideslip angle nearly constant. la...

The ALOS Kyoto & Carbon Initiative is an international endeavour initialized by NASDA, with the main objective to support information needs raised by the UNFCCC Kyoto Protocol and by the international global carbon cycle science community, by provision of systematic, consistent, repetitive and regional scale data of the global forest cover. Of central importance for the Initiative is a Dedicate...
