This dataset, published by Rennes Métropole, provides a layer generated by algorithms that estimates the theoretical location of trees, calculated from a classified digital surface model (MNS) and a digital terrain model (MNT). Attributes include tree height (arbre_h, derived from the difference between maximum and minimum elevation), crown height (houppier_h, roughly two-thirds of tree height), and crown radius (houppier_r). The layer offers a modelled, GIS-based inventory of tree positions and dimensions across the Rennes Métropole area, useful for urban vegetation analysis and planning purposes.”}Cette couche créée à l'aide d'algorithmes, localise l'emplacement théorique des arbres calculé sur la base d'un MNS classifié et d'un MNT. Parmi les attributs : - arbre_h = hauteur de l'arbres (issue de l'opération max - min) ; - houppier_h = hauteur du houppier (arbre_h/3 x2) ; - houppier_r = ra...
