GISを活用した台風による森林災害分析の試み

抄録

The purpose of this paper is to analyze the damaged state of forest by a typhoon and its recovery using GIS. Digital ortho-photographs, made by a GIS application were analyzed. The result shows that multiple layer operation between digital ortho-photographs and various thematic maps was effective in explaining the state of typhoon damaged forest. The recovery from typhoon-damage was also examined in relation to 50m buffer zones from forest road. The result shows that the location of forest roads had significant influence on damaged forest recovery.
