Large-Scale Forest Height Mapping by Combining TanDEM-X and GEDI Data

Abstract: The present study addresses the development, implementation and validation of a forest height mapping scheme based on the combination of TanDEM-X interferometric coherence and GEDI waveform measurements. The very general case where only a single polarisation TanDEM-X interferogram, a set of spatially discrete GEDI waveform measurements and no DTM are available is assumed. The use of GEDI waveforms to invert the TanDEM-X interferometric measurements is described together with a set of performance criteria imple… Show more

“…The SeEm-SINC model incorporates two semi-empirical parameters with the help of a small amount of LiDAR data, which makes the model adaptive to the forest scenario and the baseline configuration [43]. The correlation between InSAR coherence and forest height is preferred in this model than in SINC function model, so it reduces certain systematic bias present in the SINC model in some extent [34].…”

“…In order to help better contextualize the performance of the proposed DL model, we implemented a high level comparison of the baseline scenario with the RVoG model, which is often used in the literature [23], [24], [73], [74]. Given the relationship expressed in (3), the RVoG model parametrizes the vertical reflectivity function F (z) as a two-layer model consisting of a Dirac-like ground component and a vegetation volume component, which is modelled as a continuously extended volume layer of randomly oriented scatterers [21].…”

“…A canopy height estimation accuracy was evaluated over the tropical forest area of the Lopé National Park (Gabon), resulting in a peak performance of 8.62m RMSE (r 2 = 0.40). In [24], the authors presented a similar scheme for mapping forest height from TanDEM-X single-polarization data by combining interferometric coherence maps and GEDI waveform measurements over Tasmania. They validated the technique against airborne LiDAR reference data, achieving a RMSE of 7.3m (r = 0.66).…”
