This study dealt with the analysis of the changing of thermoscape, which indicates the pattern of surface temperature condition of landscape elements, such as concrete building, trees, topiary, lawn and bare soil. Source of data was the visual data of surface temperature of those landscape elements that obtained by operating infrared thermovision camera which connected with video cassette recorder. The visual data were then employed with computer system for visual image analysis. Based on each surface temperature of landscape element, we compared the changing of surface temperature pattern through 24 pieces of thermoscapes running for 24 hours, and we analyzed each pattern of surface temperature condition. Evaluating through the sequential thermoscapes, there was considerable difference of thermal condition of landscape element each to other. Tulip tree showed the similar changing pattern of surface temperature with that of air temperature, and concrete building showed different surface temperature in large number between the day and night. The study showed the changing pattern of thermoscape, that canopies of vegetations acted as lower surfaces temperature at mid day, but on the other hand the concrete building showed different surface temperature before and after receiving solar radiation, considerably. From the scene of thermoscapes, it was clear that, the concrete building was the domain of high surface temperature, while vegetations was the domain of low surface temperature.
