The primary purpose of this study was to measure the cooling effect of forests on the surrounding areas using GIS analysis techniques. To achieve the research purpose, I selected the area surrounding Cheongju Industrial Complex in Cheongju city and downloaded Landsat 8 data for this area. First, the LST (Land Surface Temperature) value and the UCI (Urban Cool Island) value were obtained using Landsat 8 images. Also, several geospatial analysis techniques were used to measure the cooling effect of forests on the surrounding areas. 3D visualization, profile analysis, and Valley Depth techniques have been found to be very useful in vividly expressing the cooling effect of forests on the surrounding areas. As a result of the analysis, the size of the wood, the distance to the forest, the vegetation density of the woods, and the distance between forests were proved to be the factors that greatly influenced the cooling effect of the wood on the surrounding areas. In particular, the distance between forests can be used as an essential indicator for understanding the synergistic cooling impact of neighboring forests on the surrounding areas. The result of this study can be used as valuable reference material for managing forests and green spaces in the future.
