Relationship Between PALSAR Backscatter and Surface-Roughness Parameters From Iron Laterites in Carajs, Amazon Region

The objective of this investigation was to evaluate the influence of micro- and macrotopography on PALSAR fine-beam dual backscattering in the characterization of iron laterites in Carajs Province, Amazon Region. The moderate linear correlation between sigma{0} and surface roughness indicated that,...

description The objective of this investigation was to evaluate the influence of micro- and macrotopography on PALSAR fine-beam dual backscattering in the characterization of iron laterites in Carajs Province, Amazon Region. The moderate linear correlation between sigma{0} and surface roughness indicated that, only for L-HH polarization, sigma{0} was modulated by the morphology of the geological surfaces.
