The data in this mosaic covers a wide range of sea states and wind speeds which accounts for the variation of the backscattering from the water. The final output mosaic contains five layers which represent total power followed by calibrated σ0 intensities for all combinations of horizontal and vertical polarizations (i.e. HH, HV, VH and VV) respectively. The input sample spacing is approximately 7.5 meters in slant range. The final orthorectified mosiac output is mapped to the UTM 30 S D000 (NAD 83) projection with 10 meter spacing.
