Estimation of CO2 sequestration by the forests of Oita Prefecture, Japan, was implemented.
LANDSAT ETM+(May 25, 2002 and Dec 30, 2006) and ALOS PALSAR (Sep 15, 2009 and
Oct 14, 2009) satellite remote sensing data of the study area were acquired and were
analyzed with IDRISI Andes/Taiga GIS software platform. Hybrid classification was
performed with a maximum likelihood method for producing a detailed land cover map and
calculating the total area of the forests (coniferous, deciduous broadleaf and evergreen …

CO2 sequestration of the forests in Oita Prefecture, Japan, was estimated using satellite
remote sensing data. First, hybrid classification of the optical LANDSAT ETM+ data was
performed using GIS to produce a detailed land cover map. CO2 sequestration for each
forest type was calculated using the sequestration rates per unit area multiplied by the forest
areas obtained from the land cover map This results in 3.57 MtCO2/yr for coniferous, 0.77
MtCO2/yr for deciduous broadleaf, and 2.25 MtCO2/yr for evergreen broadleaf, equivalent to …
