{ "currentVersion": 10.51, "id": 1, "name": "Orthophotos 2021 - Maillage", "type": "Feature Layer", "description": "Le maillage des orthophotos 2021 est un découpage, sous forme de polygone, de la Wallonie en mailles carrées de 2 km x 2 km de côté ayant comme origine la coordonnée (0,0). Il est propre au Service public de Wallonie. Des données attributaires telles que les dates de vol sur la maille (première et dernière), les caractéristiques de l'image (largeur, hauteur, canaux, date, etc.), le fournisseur, etc. sont associées à chaque maille du maillage.\n\nLes orthophotos sont disponibles, entre autres, sous forme d\u2019images (au format Geotiff, pour les plus récentes) de la dimension d\u2019une maille.\n\nL\u2019ensemble des fichiers images appartenant à une feuille IGN au 1/50.000 est groupé dans un même dossier portant le numéro de la feuille.\n\nL\u2019utilité principale des mailles est de faciliter la recherche d\u2019un fichier image donné au sein de l\u2019arborescence du disque en permettant d\u2019identifier le nom de la maille (et donc du fichier image) et de la feuille (et donc du dossier contenant le fichier) sur base d\u2019une vue cartographique.\n\nConsultez les métadonnées sur :http://geoportail.wallonie.be/catalogue/9b1bda66-accd-452c-a80e-f1309a25f5e4.html",
