| Research Abstract |
In this study, I classified the tropical land cover distribution with PALSAR data of the ALOS and I worked at the field for the ground truth in order to inspect the accuracy. As a result, from PALSAR data, I was not able to perform the classification equal to optical satellite imagery although some land cover classification was possibility. This is why the land cover is detected clear whether forest or other distinction from visible and near-infrared light when the optical imagery was analyzed. In the other hand, forest is detected by analyzed with PALSAR using the result of volume dispersion. But the PALSAR analysis has much disturbance of scattering, for example the directionality of the furrow in the field.
