An above-ground biomass map of African savannahs and woodlands at 25 m resolution derived from ALOS PALSAR

open access: yes, 2018
Savannahs and woodlands are among the most important biomes in Africa: they cover half of sub-Saharan Africa, provide vital ecosystem services to the rural communities, and play a major part in the carbon budget.

Monitoring of long-term land subsidence from 2003 to 2017 in coastal area of Semarang, Indonesia by SBAS DInSAR analyses using Envisat-ASAR, ALOS-PALSAR, and Sentinel-1A SAR data

open access: yesAdvances in Space Research, 2019
Land subsidence is a critical issue that large cities located in coastal areas, such as Semarang, Indonesia, must address. The monitoring of land subsidence is vital for predicting and mitigating the disasters that such subsidence may cause.

Multi-Sensor InSAR Analysis of Progressive Land Subsidence over the Coastal City of Urayasu, Japan

open access: yesRemote Sensing, 2018
In earthquake-prone areas, identifying patterns of ground deformation is important before they become latent risk factors. As one of the severely damaged areas due to the 2011 Tohoku earthquake in Japan, Urayasu City in Chiba Prefecture has been ...

Predicting soil organic carbon content in Spain by combining Landsat TM and ALOS PALSAR images

open access: yesInternational Journal of Applied Earth Observation and Geoinformation, 2020
Soil organic carbon (SOC) is the largest carbon pool and a key property of ecosystems. Compared with traditional field surveys, remote sensing (RS) represents a more efficient approach to mapping SOC, especially in larger-scale areas.

CROP SPECIES RECOGNITION AND DISCRIMINATION PADDY-RICE-GROWINGFIELDS FROM REAPED-FIELDS BY THE RADAR VEGETATION INDEX (RVI) OF ALOS-2/PALSAR2 [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
The Japanese ALOS-2 satellite was launched on May 24th, 2014. It has the L-band SAR, PALSAR-2. Kim,Y. and van Zyl, J.J. proposed a kind of Radar Vegetation Index (RVI) as RVI = 8 * σ0hv / (σ0hh + σ0vv + 2* σ0hv) by L-band full-polarimetric radar data ...

Estimation of Aboveground Biomass for Different Forest Types Using Data from Sentinel-1, Sentinel-2, ALOS PALSAR-2, and GEDI

open access: yesForests
Forest aboveground biomass (AGB) is integral to the global carbon cycle and climate change study. Local and regional AGB mapping is crucial for understanding global carbon stock dynamics.

Mapping Regional Inundation with Spaceborne L-Band SAR

open access: yesRemote Sensing, 2015
Shortly after the launch of ALOS PALSAR L-band SAR by the Japan Space Exploration Agency (JAXA), a program to develop an Earth Science Data Record (ESDR) for inundated wetlands was funded by NASA. Using established methodologies, extensive multi-temporal

Optimizing the Global Digital Elevation Models (GDEMs) and accuracy of derived DEMs from GPS points for Iraq's mountainous areas

open access: yesGeodesy and Geodynamics, 2020
Optimizing the combined horizontal and vertical accuracy of the well-known Global Digital Elevation Models (GDEMs) of various resolutions for each country and region especially in Iraq's mountainous areas is still questionable.

Forest biomass estimation using optical and microwave imagery (Case study: Garazbon Series, Kheirud Forest) [PDF]

open access: yesمجله جنگل ایران, 2020
Estimation of forest aboveground biomass is important in regional carbon policies and sustainable forest management. Since forests are the largest carbon store, it is important to evaluate the forest biomass to estimate carbon storage and its impacts on ...
