DETAILED CHARACTERISTICS OF SUMMER RADIATIVE TEMPERATURE IN OSAKA CENTRAL AREA : Analysis of radiative temperature in Osaka central area by using thermal image and GIS data Part 1

Abstract

This study aims at quantitative investigation of the radiative temperature distributions in detail for the Osaka central area, by overlaying airborne thermal image with GIS data. Principal findings we have described this report are the following.(1) In the park, the radiative temperature of "Grass" is lower.(2) In the water area, the radiative temperature of the large river is lower.(3) On the wide east-west road, the radiative temperature on the north side of the road is higher than that of south side.(4) The radiative temperature of the intersections is higher than that of other road areas.
