RELATED ANALYSIS BETWEEN LAND COVER AND TEMPERATURE GRADIENT IN WEATHER OBSERVATION POINTS

−Analysis utilizing building height information that was estimated from ASTER GDEM−

Abstract

The purpose of this study is to get the height information using the ASTER GDEM, and grasp the relationship between climate change and land cover including the height information. Also, verify the usability of ASTER GDEM in urban environmental field.
By including the height on land cover information, enables classification in the height direction, for example, are “forest and grassland,” “low-rise cities and high-rise city”. In climate change, shows the highest figure, about 0.06 (°C/year) at the urban classes. Also, confirmed tendency to “Hidamari effect” at the forest class.
