     View Summary

    本論文では,ベトナムのラオカイ地域とカントー地域を対象に衛星画像を使用して,土地利用/土地被覆(LULC)分類のためのオブジェクトベースファジー分類手法を実証した.ラオカイ地域の場合,中解像度の衛星画像によるスペクトル指数画像を用いて分類を行った.カントー地域の場合は,高解像度の衛星画像を導入し,同様の手法を試みた.結果は,ラオカイとカントー地域において,90%以上の精度を誇る土地利用図を作成することができ,当手法の有効性を明らかにした.

     View Summary

    この研究は,地滑り危険度モデルのパフォーマンスを向上させるために,機械学習手法を利用した.ベトナム北西部の紅河流域の上流域を調査対象地とし,GISデータベースを確立した.データベースを使用して,提案された機械学習モデルを構築および検証した.その結果,分類精度がトレーニングデータで93.81%であり,検証データで83.4%であることから提案されたモデルの精度は高いことを示した.したがって,本手法は,地滑りモデリングに使用される効率的なツールであることが証明できた.この研究は,地すべり危険度予測の向上を示した.
