Abstract: Abstract Global urbanization and climate change are significant challenges for any country worldwide to achieve sustainable goals. Urban is closely linked to deteriorated environment quality and urban heat islands that are accelerated by greenspace shrinkage. Blue, green, and gray infrastructures (BGGIs) are the leading influential components of urban air temperature. The spatial arrangement of the BGGIs is also considered to optimize their positive and negative effects on urban planning. This chapter applied the combination of remote sensing, GIS, and landscape metrics to analyze the relationship between the BGGI and land surface temperature (LST) of Hue city. The LST was retrieved from the Landsat 8 OLI/TIRS image, while the BGGIs were grouped from land use/land cover classified from the Sentinel-2A image. Ten landscape metrics were calculated to examine the spatial arrangement of the BGGIs landscape pattern associated with the LST using the grid size of 10 x10 pixels. The analysis of variance (ANOVA) test demonstrates that the blue and green infrastructures ease the LST by approximately 2 °C and 3.5 °C compared to the gray infrastructure (p
