This dataset, published as open data by Bordeaux Métropole, provides the reference grid of tiles ('dalles') used to divide the metropolitan territory into sections of 1.4 km by 1 km. This grid facilitates the distribution and use of aerial orthophotographs and digital terrain models (elevation data), which are structured according to the same tiling system. The dataset is useful for locating and retrieving specific orthophoto or elevation data tiles covering a given area within Bordeaux Métropole.Dictionnaire Public Pour faciliter la diffusion et l'utilisation des orthophotos et du MNT (données altimétriques), le territoire de Bordeaux Métropole a été découpé en dalles de 1,4 km par 1km. Ce jeu de données représente la grille de référence de ces dalles. Elle s'applique pour les orthophoto...
