Forest Structure Change from SAR Tompraphy

Forest Structure Change from SAR Tompraphy
Top: Polarimetric Pauli RGB composite image at L band of the Traunstein test site. Bottom: Vertical structure indices derived from 3 D radar reflectivity measurements performed in 2008 (left) and 2012 (right) over the Traunstein test site. The increase of the complexity of the forest following the thinning of many mature stands, as illustrated by the insets, is reflected by a higher vertical structure index derived from the tomographic SAR data.
