| Abstract | Radarsat-2 polarimetric data were acquired over Tapajos National Forest and surroundings in September 2008. A field campaign was planned for acquisition of ground truth points with the help of a GPS. The objective of this work was to assess the potential of polarimetric C band data on land use/land cover mapping. Complex polarimetric data were first corrected from slant to ground range, followed by the conversion of the data in the correspondent coherence and covariance matrix. These matrices were used for the Freeman-Durden decomposition, which intends to decompose the image targets according to the main scattering mechanisms in the study area. Finally, the new data representing the scattering mechanisms corner reflection, volumetric and superficial were classified by a k-means-Wishart classification. Results indicated the dominant scattering mechanisms for the study area and confirmed the importance of volumetric and superficial scattering for the discrimination between vegetated and non-vegetated areas. Classification accuracy reached around 80% for forest and pasture/bare soil classes. The conclusion presence of dense forest in most of the study area did not allow the observation of all the mechanisms of scattering in SAR data, but confirmed the volumetric and surface scattering as responsible for discrimination between plants and areas of pasture/exposed soil. Future work will evaluate different classification schemes, along with different approaches for interpreting polarimetric SAR data. | |||
