This dataset provides polygon geometries for buildings across Rennes Métropole, in western France. It serves as a reference layer for the local authority, supporting mapping, urban planning, and other municipal applications that require accurate building footprints. The dataset is maintained by Rennes Métropole and made available through its open data portal. As of July 2023, the layer was undergoing a complete overhaul and revision, so users should expect ongoing changes to its structure or content during that period.Cette couche contient les polygones des bâtiments sur Rennes Métropole. Il s'agit d'une couche de données référentielle pour la collectivité. /!\ Juillet 2023 : cette couche est cours de reprise / refonte totale.
