Estimation of Soil Moisture in an Alpine Catchment with RADARSAT2 Images

Figure 4

Scatter plots of backscattering coefficients extracted from the RADARSAT2 images versus dielectric constant measurements over pasture areas and with dielectric constant values between 4.5 and 5.5 in the case of (a) HH polarization configuration and (b) HV polarization configuration. The samples are grouped into 4 clusters according to the topographic features extracted from the DEM.
