L'Actueel Hoogtebestand Nederland (AHN) è un set di dati con dati di elevazione dettagliati e precisi per tutti i Paesi Bassi. Le informazioni
sull'elevazione sono state raccolte da elicotteri e aerei utilizzando la tecnologia
laser con una precisione verticale di 5 cm.
Il set di dati AHN3 contiene le variabili DSM e DTM di AHN 0,5 m dei Paesi Bassi.
I dati coprono il periodo compreso tra il 2014 e il 2019.
Il prodotto Digital Terrain Model (DTM) rappresenta l'altitudine del
terreno, mentre il prodotto Digital Surface Model (DSM) rappresenta
l'altitudine delle superfici più alte in quel punto.
