Modèles numériques de surface (DSM) et de terrain (DTM) dérivés des données LiDAR NEON. MNS : caractéristiques de surface (informations topographiques avec végétation et structures artificielles). MNT : altitude du sol nu (informations topographiques sans végétation ni structures artificielles). Les images sont exprimées en mètres au-dessus du niveau moyen de la mer et mosaïquées sur une grille spatialement uniforme à une résolution de 1 m. La disponibilité dans GEE peut ne pas refléter la disponibilité complète dans le portail de données NEON (lien ci-dessous).
