The image on the left shows a visualised forest plot in the hilly and densely vegetated Sungain Wein test site on Indonesia’s Borneo island. The two histograms demonstrate the Pol-InSAR derived heights (red) and ground-measured heights (blue) for L- (middle) and P-band (right). Validation plots like this one indicate a near-accurate estimation of biomass using Pol-InSAR techniques.
