Abstract
Detailed contour map is useful for geoecological study. In Japan, in the present century, airborne LiDAR (light amplitude detection and ranging) came into practical use, using this tool we could have more detail contour map which illustrate micro landform than the previous photogrammetric contour map. Furthermore, vegetation height data in wide area were available based on the airborne LiDAR data measured in the both foliate and defoliate seasons. In this study I selected 4km2 in area at the north-slope of Mt.Futatsumori, at the boundary between Aomori and Akita prefecutures in northeast Japan. And we combined 19-classifed micro landform classification map that was interpreted from LiDAR contour map, vegetation height data and 6-classifed vegetation map derived from airborne hyper spectral sensor data in the study area. Finally, I mapped 16-classified geoecological map using decision tree method. The obtained map is thought to be effective not only in biodiversity evaluation but also in the countermeasures for natural environment protection.
