/The authors have been doing the project of trial produce of landscape-ecological map of Shiretoko Peninsula, where is Natural Heritage Area of Japan, Hokkaido Island.

/Basic legend of landscape-ecological maps consists of the combination of vegetation classification and landform classification.

/In this presentation, the authors introduce three dimensional vegetation structure map using LIDAR survey data for legend of landscape-ecological map.

/This research project have been promoting by the budget of the Ministry of Environment.

Introduction

Background(characteristics of LIDAR survey data)

/Last pulse LIDAR data in winter season is useful for detection of micro landform under forest area

/Vegetation classification has been down using three dimensional vegetation structure detected by the difference between LIDAR data in two seasons

summer winter

• The authors produce three dimensional vegetation map using LIDAR data on south-east foots of Mt. Rausu on Shiretoko Peninsula.

• LIDAR vegetation map is correspond to Actual Vegetation Map and ground survey data.

• Result of overlay between automatic landform classification and vegetation classification shows vegetation on Mt. Rausu depend on elevation.

• The authors will produce legend of landscape-ecological map combined with three dimensional vegetation structure and micro landform classification for the evaluation of biodiversity in Natural Heritage Area.
