This dataset from Rennes Métropole provides a polygon layer of buildings shown on the cadastral (land-registry) map. Each building is represented by its ground footprint, allowing distinction between light structures and permanent (solid) buildings. The layer covers the Rennes Métropole area in France and can be used for urban planning, land-use analysis, and mapping applications requiring accurate building outlines derived from official cadastral sources.Cette couche de polygones contient les bâtiments qui figurent sur le plan cadastral. Les bâtiments sont figurés par leur emprise au sol. Il est possible de distinguer les bâtiments légers et les bâtiments en dur.
