The authors try to produce landscape ecological maps for estimation of biodiversity using airborne laser survey data (LIDAR data). A studied area is north foot of Mt. Dougo, Chugoku Mountains, as a ‘Satoyama’ rural area. Basic legend of landscape ecological map consists of the combination of three dimensional vegetation structure classification using detailed DSM (Digital Surface Model) and micro landform classification using detailed DEM (Digital Elevation Model). As LIDAR data is useful for detection of micro landform under forest area by using last pulse data in autumn season, automatic landform classification was done using autumn season DEM. Vegetation classification was done using three dimensional vegetation structure detected by the difference between DSM data in two seasons. In addition, many kinds of field surveys were carried out for ground truth of such as vegetation survey, measurement of forest structure and geological survey. As the results of overlay analysis of LIDAR vegetation maps and automated landform classification maps, it has become clear that J. mandshurica are dominant in historical iron sand mining (Kanna-Nagashi) site on Mt. Dougo.
