El Actueel Hoogtebestand Nederland (AHN) es un conjunto de datos con información de elevación detallada y precisa para todo el territorio de los Países Bajos. La información de elevación se recopiló de helicópteros y aeronaves con tecnología láser y una precisión vertical de 5 cm.
El conjunto de datos AHN4 contiene las variables DSM y DTM de AHN de 0.5 m de Países Bajos.
Los datos abarcan el período comprendido entre 2020 y 2022.
El producto del Modelo Digital del Terreno (MDT) representa la elevación del suelo, mientras que el producto del Modelo Digital de Superficie (MDS) representa la elevación de las superficies más altas en ese punto.
