Description
The problem of heat environment in urban area has become more obvious recently. One of the causes of this problem relates to the urban land covers. Especially, artificial land surfaces such as concrete, asphalt and so on have been expanded under urbanization and have made the problem more worsen continuously. Therefore, this study firstly acquired the fine land cover information by using the object based classification method which has become popular recently. Then, the acquiring land cover information was verified the accuracy compared with actual land covers. Moreover, relationship between land cover information and land surface temperatures were analyzed by two different statistical methods of the ordinary least squares and the geographically weighted regression. Finally, the reproducibility of the land surface temperatures by both methods were examined.
