Polarimetric Parameters for Growing Stock Volume Estimation Using ALOS PALSAR L-Band Data over Siberian Forests
In order to assess the potentiality of ALOS L-band fully polarimetric radar data for forestry applications, we investigated a four-component decomposition method to characterize the polarization response of Siberian forest. The decomposition powers of surface scattering, double-bounce and volume scattering, derived with and without rotation of coherency matrix, were compared with Growing Stock ...
متن کاملStandwise Change Detection for Growing Stock Using Repeat-pass Alos Palsar / Palsar-2 Data
This study demonstrates the possibility of detecting the changes of growing stocks in mountainous forest stands derived from ALOS PALSAR and PALSAR-2 images. The ALOS PALSAR were obtained over the Kwangneung Experiment Forest (KEF, Korea) during the period of nineteen and a half months from the April 26, 2009 to December 12, 2010, whereas the PALSAR-2 data were acquired on the April 7, 2015. Th...
متن کاملMapping Canopy Height and Growing Stock Volume Using Airborne Lidar, ALOS PALSAR and Landsat ETM+
We have investigated for forest plantations in Chile the stand-level retrieval of canopy height (CH) and growing stock volume (GSV) using Airborne Laser Scanner (ALS), ALOS PALSAR and Landsat. In a two-stage up-scaling approach, ensemble regression tree models (randomForest) were used to relate a suite of ALS canopy structure indices to stand-level in situ measurements of CH and GSV for 319 sta...
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 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...
