Creation of a Map of Tohoku Forest District Area Using Satellite Images

AWAYA Yoshio and SHINBAYASHI Shouichi


Abstract
The forest planning district map of the Tohoku Regional Forest Management Office was created using satellite data to show forest cover information for forest management. Nine scenes of Thematic Mapper on Landsat were mosaicked and the intensities of all images were adjusted at the same time, then the mosaicked image was overlaid on the transverse mercator coordinate system of Japan. Forest management office boundaries and 'Midorino Kairou' (forest corridor) boundaries were displayed over the mosaicked image, on which the national forest areas were brightened. The result showed the extents of the national forest, the corridors and vegetation there. The resulting image showed the richness of deciduous forests in the national forest and discontinuous areas of the corridors with vegetation type. Thus the satellite map can show information that is useful for forest management. It is also possible to overlay other kinds of geographical information that are useful for forest management such as elevation on the satellite map.

Key words : corridor, forest management office, national forest, satellite map
