Mapping Forest Thinning, Systemic and Selective Logging Operations Using Various Imaging Modes of X-Band SAR Images.
IGARSS(2021)
Abstract
In this study, we evaluate the performance of several imaging modes of X-band satellite SAR data in mapping various forest logging operations. We use stripmap and spotlight data acquired by DLR's TanDEM-X mission and ICEYE SAR satellites. Also, the potential of InSAR coherence data is evaluated. Experiments are performed over the study site located in the central part of Finland. Reference data are represented by forest management plans and harvester logging tracking reports. Our results indicate that not only clear-cutting, but also forest thinning operations can be detected using advanced imaging modes of satellite SAR data even at X-band, primarily using high resolution imaging modes and interferometric SAR capability.
