Abstract

Potential for synergetic use of Sentinel- 1 and Sentinel-2 for mapping biomass of Mediterranean shrublands is investigated. As preliminary research, backscatter and its ratio from Sentinel-1 (C-band dual polarization SAR), and NDVI from Sentinel-2 (13 bands multi-spectral data) are assessed by using the NDVIR biomass model. Then the fusion biomass model is proposed based on shrub volume formations. The fusion model is verified by filed survey data which measured shrub height and diameter applyied into the allometric model. The proposed fusion model shows around 14 % improvement of accuracy compared to the single sensor model (r-square: from 0.72 to 0.86, RMSE: from 0.158 to 0.109).
