広域バイオマス推定のための森林立地環境時系列データセットの作成および環境区分ソフトウェアの開発

抄録

        We developed technologies to collect site environment parameters (ex. surface temperature, period of flooding, and terrain condition) and to create a site environment map that shows the diversity of site environment conditions of Amazon River basin. The filtering method “kalmfit” and a discrete time-series modeling method were applied to the 8-days composite of MODIS dataset for removing the influences of clouds and other noises on the data set. Data sets consists of NDVI, NDII, day/night brightness temperature and spectral clusters dataset in 2001 to 2009 every 8day intervals. A methodology for classification of a site environment conditions were developed. The terrain data derived from digital terrain model were also introduced and a site environmental map with 500m resolutions was created. [This abstract is not included in the PDF]
