Zusammenfassung
The characteristics of land covers in the central part of Kyoto City are analysed by using the Ikonos data with 4m resolution. Albedo is presumed from panchromatic data. It is confirmed that albedo of the elementary school yard is high, and that of the tiled roof on the wooden house is low. It is confirmed from NVI image data that the green ratios in the imperial palace, the castle, parks, slopes, temples, and shrines are high. The parameters of ground surface heat budget are set by using Ikonos data, and the thermal environment in the central part of Kyoto City in summer is analysed using the local scale numerical simulation model. Based on an analytical result of the Ikonos data, it is calculated to improve albedo of the tiled roof on the wooden house, and the impacts on the thermal environment are analysed.
