Discriminating Drivers of Deforestation by using a Velocity Change EstimationApproach with ALOS-2/PALSAR-2 ScanSAR Data

摘要

Forests in Indonesia have been suffering severely from various degradation processes including deforestation from bothlogging activities and forest fires. The L-band SAR aboard JAXA’s ALOS-2 provides outstanding means for the monitoring oftropical forests due its cloud and canopy penetration capability. In this study we demonstrate how the use of velocity changeestimation with cross-polarized HV images can not only help to detect deforestation areas, but also gives information about the speedof different forest changes and thereby allows discriminating the drivers of deforestation.
