Methodology of Detecting ARD area by Remote Sensing
Journal of Forest Planning
Under Article 3.3 in the Kyoto Protocol, it is necessary to monitor aforestation, reforestation and deforestation (ARD) activities between 1990 and the peried of 200g2012 to account net carbon storage by forest. In this study, we developed detecting ARD method by subtraction operation using two LANDSffI' Thematic Mapper images in Higashi-Shirakawa vMage, Gifu prefecture. [[he processing flow ei geometric correction, topographic correction, adjusting level of digital number and change detection
... d change detection was established, The consideration of selecting most efiective bands for change detection and screening ovcr detection was performed, The results were evaluated accurauy by truth data which was manipulated digital ortho-photo images and IKONOS satellite images. This method can distinguish land-cover type changes and decide a thresheld value automatically and ebjectively, the point is exactly an advantage, therefore this method can become usefu1 method when ARD is menitered for the whole country in the future.
