Development of an evaluation technique for heat island phenomenon and open space effect by using high resolution thermo graph data

1.夏季热图像数据的获取2006年8月3日上午11点开始，利用直升机在30分钟内拍摄了以南海难波站为中心的南北×东西2.5km范围内的可见光图像和热图像，拍摄后在计算机上对各动画拍摄的捕获图像进行拼接合成，制作了一张可见光图像和热图像.图像处理和测量将热图像形成GIS数据，在计算机上合成可见光和热红外图像，并进行处理，使其与地表成分形成对比。结果，在灌木区和乔木植被区，没有明显的地表温差。在灌木林乔木植被混杂区，地表温度差异在一般种植区显著。

1. Acquisition of the heat image data of a summerPhotography of the visible light of the range of 2.0km of 2.5km of north-south x east and west centering on the Nankai Namba station and a heat picture was performed using the helicopter from 11:00 on August 3, 2006 in 30 minutes.Mosaic composition of the capture picture captured from each animation was carried out on the computer after photography, and the visible light picture of one sheet and the heat picture were created.2. Image processing and measurementThe heat picture was formed into GIS data, performed composition of visible light and a heat infrared light picture on the computer, and it processed it so that contrast with a surface component might be possible.As a result, in the shrubbery region and the arboreal vegetation region, it became clear in that there is no big surface temperature difference. In a shrubbery arboreal vegetation jumble region that a surface temperature difference significant in the average planting region.
