| Abstract | The ALOS PALSAR (Phased Array type L-band Synthetic Aperture Radar) sensor can provide full polarimetric data (HH, HV and VV) for scientific purposes. Dutra et al.(2008) showed that, from the three possible channels, HH-HV channels presented better classification results when the following five classes are used: primary forest, secondary forest, bare soil, agriculture and degraded forest. This study is extending the former work by increasing the number of classes, including now pasture and dirty pasture, and testing if contextual classification can improve the overall accuracy. The results showed that the contextual classification does improve the per point classification results, however not as good as region classification when SEGSAR segmentation is used. Region based classification, particularly the one developed to take in account as much as possible the radar statistical behavior, performed better for VV-HV channels with 98.6% of overall accuracy using gamma filter on image and 92.7% without gamma filter on image. Comparing this study with Dutra et al.(2008), it was possible to observe that the better channels are different, with only two classes more, which shows that the best channels set is totally dependent on a particular set of classes being considered. So, the best dual polarization depends on the desired land use application, but the HV channels seems to be always chosen. The presence of HV channel in the dual polarization products provide the better combinations for general mapping of the rain forest problem. | |||
