Abstract

The purpose of this study is to analyze and verify the spatial distribution property of the surface temperature with urban spatial information, related with land-cover, NDVI, and characteristics of topography in Daegu metropolitan area, Korea, using remotely sensed data and GIS. In this study, the surface temperature, land-cover patterns and NDVI were extracted from multi-temporal Landsat TM images, In addition topographic factors, such as elevation, slope, and aspect were analyzed through GIS spatial analysis. The result showed that the average correlation degree of 0.77 between extracted surface temperature and AWS observed data and the negative(-) correlation more than 80% was identified by the results from the correlation and regression analysis of the extracted surface temperature from Landsat TM images with NDVI. Also this research verified the distribution of the urban surface temperature was very different depends on various land-cover types of surrounding areas. These results will be worked as one of the major factors for environmentally sustainable urban planning considering the characteristics of weather environments in the near future.
