Forest phase analyzer, forest phase analysis method and program

摘要

PROBLEM TO BE SOLVED: To make forest physiognomy visible on the basis of only airborne laser-measured data.SOLUTION: A feature quantity extractor 20 figures out, on the basis of airborne laser-measured data 30 acquired by scanning an object area including forests, one or more kinds of feature quantities including reflection pulse indicators at measuring points, determined correspondingly to the number of reflection pulses relative to laser irradiation pulses. A color image generator 22 is means of generating color images of the object area. The color image generator 22 prescribes the pixel values of the color images on the basis of feature quantities in the area corresponding to the pixels.
