| Outline of Final Research Achievements |
Remote sensing is the most effective tool for peat mapping because of the difficulty in accessing peatlands. However, the upper layers of tropical peatlands are mostly hidden under forests, and it is extremely difficult to identify and map the boundaries of peatlands accurately. A highly precise detecting technique to make accurate maps of peatlands is required to evaluate the impact of destruction caused by forest fires due to the burnt surface soil and forest on peatlands, and by the drastic changes in land-use due to the recent development to transform peatlands into oil palm plantations. In this study the method was developed to classify forest into three types, i.e., oil palm trees of 8-9 year-old, tropical forest trees dominant, and 2-7 year-old oil pal trees, from the leaf surface spectral reflectance characteristics. The vertical movement of peatland surface in the range between -4 - 3.8 cm were detected from 2015 - 2016 SAR images using interferometoric technique.
