ALOS-PALSAR image simulation in various polarization bases [PDF]

, 2002
The ALOS-PALSAR is the first L-band space-borne SAR in the world equipped with a fully polarimetric data taking function. For the data utilization purpose, the authors have examined the polarimetric performance (scattering matrix and resultant images ...

Soil erosion responses to climate change in a tropical monsoon‐dominated river basin ‐ A geospatial perspective

River, Volume 5, Issue 2, Page 222-249, May 2026.
Abstract Soil erosion is a major global environmental and socio‐economic challenge, with impacts particularly severe in tropical, monsoon‐dominated mountainous regions, where heavy rainfall, steep terrain, and unsustainable land‐use practices accelerate land degradation.

ALOS Palsar Data in Boreal Forest Monitoring and Biomass Mapping

, 2008
Polarimetric Palsar data were ortho-rectified for analysis of polarimetric signatures of forested stands. A strong positive correlation of 0.93 was found between Palsar HV amplitude and forest stem volume in stands with a stem volume of 150 m3/ha or ...

Nine‐Year L‐Band InSAR Time Series of Tectonic and Non‐Tectonic Surface Deformation in Northern California

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract This study evaluates the performance of ALOS‐2 ScanSAR time series for resolving tectonic, volcanic, hydrologic, and geomorphic deformation across Northern California. Beginning in 2021, ALOS‐2 acquired ScanSAR data with a 14‐day repeat interval over the region, providing the closest available analog to the recently launched NISAR mission. The

An Explainable and Optimized Machine Learning Framework for Multisensor Remote Sensing‐Based Land Use and Land Cover Classification

Transactions in GIS, Volume 30, Issue 3, May 2026.
ABSTRACT Land use and land cover (LULC) mapping supports environmental monitoring and spatial planning, but classification performance often suffers in feature spaces that combine multiple data sources with redundant predictors. This study compares five feature selection methods (mRMR, ReliefF, Boruta, RFE, HSIC‐Lasso) with three tree‐based classifiers
