This dataset from the Bordeaux Métropole open data portal provides polygon features mapping urban heat and cool islands, derived from an analysis of land surface temperatures recorded in 2022. It covers the Bordeaux Métropole area in France and is intended to support studies of urban microclimates and heat exposure. In addition to standard open data formats, the dataset is also available for download in AutoCAD DWG format, making it usable within GIS and CAD environments alike.Dictionnaire Public Ce jeu de données présente, sous la forme d'objets surfaciques, les ilots de chaleur ou de fraicheur urbains basés sur l'analyse des températures de surface de 2022. Ce jeu de données est disponible dans un format additionnel : Téléchargement au format AutoCAD DWG
