Odorous emissions from large industrial complexes exhibit significant spatial and temporal variability, which complicates quantitative evaluation and source identification. Odor perception may occur even at low concentrations, and emission characteristics are strongly influenced by industrial processes, meteorological conditions, and local topography. Therefore, odor management strategies based solely on compliance with emission standards have inherent limitations. The Yeosu National Industrial Complex was designated as an odor management area in 2019, and annual surveys of complex odor dilution ratios and specified odor substances have been conducted since then. Despite the accumulation of monitoring data, odor complaints from nearby residential areas have continued. In this study, multi-year (2020-2024) odor monitoring data were integrated with complaint records, and GIS-based mapping and visualization were applied to examine the spatial distribution characteristics of measured odor levels and complaint locations. Map-based visualization facilitated visual comparison of complaint locations and monitoring sites and enabled a comparative assessment between monitoring sites and complaint locations. The results revealed clear spatial heterogeneity among monitoring sites. In particular, the A3 monitoring site recorded the highest annual average dilution ratio, indicating persistent structural characteristics of odor emissions in that area. Although measured odor intensity was relatively higher in summer, complaint frequency peaked in spring and autumn, suggesting that meteorological conditions and human exposure patterns significantly influence perceived odor nuisance. These findings demonstrate that measured odor intensity alone does not fully explain complaint occurrence and highlight the necessity of integrated odor management approaches that incorporate spatial dispersion characteristics, seasonal variability, and community exposure factors. The results can serve as a foundational basis for improving monitoring site placement and establishing spatially differentiated odor management policies.
