A workflow combining QGIS and R is used to process Landsat 8/9 imagery, calculating Land Surface Temperature (LST) to estimate urban-rural thermal differentials. The main contribution is a reproducible methodology for DSUHI analysis, which also compares LST results derived from Landsat Level-1 and Level-2 data. Findings highlight key differences in DSUHI characteristics among the cities and the implications of using different data processing levels.7 p.application/pdfengcc-by-nc-nd (c) Bilbao, 2025http://creativecommons.org/licenses/by-nc-nd/3.0/es/Canvi climàticTeledeteccióTreballs de fi de grauClimatic changeRemote sensingBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
