The Olympic Games are a sporting event and catalyst for urban development in the host city. In this study, we utilized remote sensing GIS techniques to examine impact of infrastructure on surface temperature areas. Using Landsat Series Collection 2 Tier 1 Level data, cloud computing, Google Earth Engine (GEE) methods, study examines effects various facility planning different historical moments location typologies: monocentric, polycentric, peripheric clustered ring. GEE code applies from Paris’24 Munich’72. However, paper focuses specifically representative cases Paris’24, Tokyo’20, Rio’16, Beijing’08, Sydney’00, Barcelona’92, Seoul’88, Montreal’76. is not only concerned with obtaining absolute Land Surface Temperatures (LST), but rather relative influence mega-event infrastructures mitigating or increasing heat. As such, locally Normalized Temperature (NLST) was purpose. some cities (Paris, Tokyo, Beijing, Barcelona), it identified that has resulted green spaces, creating "green spots" contribute lower-than-average temperatures. should be noted there significant variation within intensely built-up areas, such as villages surrounding areas stadium, which can become “hotspots”. Therefore, important acknowledge typologies have varying impacts city heat islands, polycentric ring displaying effect. This research contributes computing method updated future adapted other mega-events utilizes widely available data source specific context.
