Using Polarimetric Interferometric Alos/palsar Data to Estimate Stem Volume in the Amazon Region
In the Brazilian Amazon, where the forest sector plays a particularly important role in the economy [1], a better understanding of stem volume distribution is necessary to support those who manage forests for wood production during strategic planning, resource allocation and operational decisions. In addition, international agreements are underway for developing global observation systems to as...
متن کاملPolarimetric Calibration of ALOS/PALSAR
This report presents the polarimetric calibration results of ALOS/PALSAR and discusses a stability of polarimetric calibration parameters during the calibration phase of ALOS and an influence of Faraday rotation on them. PALSAR is the first spaceborne polarimetric L-band synthetic aperture radar and its polarimetric data is expected to be utilized in various remote sensing applications. However...
متن کاملEstimating Forest Aboveground Biomass by Combining ALOS PALSAR and WorldView-2 Data: A Case Study at Purple Mountain National Park, Nanjing, China
Enhanced methods are required for mapping the forest aboveground biomass (AGB) over a large area in Chinese forests. This study attempted to develop an improved approach to retrieving biomass by combining PALSAR (Phased Array type L-band Synthetic Aperture Radar) and WorldView-2 data. A total of 33 variables with potential correlations with forest biomass were extracted from the above data. How...
متن کاملPolarimetric calibration and validation for ALOS/PALSAR
The objectives of my proposal are to calibrate and validate the polarimetric data acquired by ALOS (Advanced land observing satellite)/PALSAR (Phased array type L-band synthetic aperture radar). In this report, we show the polarimetric calibration parameter of PALSAR derived by Quegan method and Amazon data. Moreover, we confirm the accuracy of Faraday rotation angle derived from PALSAR data as...
متن کاملModeling and Mapping Agroforestry Aboveground Biomass in the Brazilian Amazon Using Airborne Lidar Data
Agroforestry has large potential for carbon (C) sequestration while providing many economical, social, and ecological benefits via its diversified products. Airborne lidar is considered as the most accurate technology for mapping aboveground biomass (AGB) over landscape levels. However, little research in the past has been done to study AGB of agroforestry systems using airborne lidar data. Foc...
