Le MNT AHN est un MNT de 0,5 m couvrant les Pays-Bas. Elle a été générée à partir de données LIDAR collectées au printemps entre 2007 et 2012.
Il contient des échantillons au niveau du sol, tous les autres éléments au-dessus du sol (tels que les bâtiments, les ponts, les arbres, etc.) ayant été supprimés. Cette version est interpolée : les zones où des objets ont été supprimés sont remplies avec des valeurs interpolées. Le nuage de points a été converti en grille de 0,5 m à l'aide d'une méthode de pondération inverse de la distance au carré.
