AHN DEM adalah DEM 0,5 m yang mencakup Belanda. Data ini dihasilkan dari data LIDAR yang diambil pada musim semi antara tahun 2007 dan 2012.
Gambar ini berisi sampel tingkat dasar dengan semua item lain di atas permukaan tanah (seperti
bangunan, jembatan, pohon, dll.) dihapus. Versi ini diinterpolasi; area tempat objek telah dihapus diisi dengan nilai yang diinterpolasi. Awan titik dikonversi menjadi petak 0,5 m menggunakan metode pembobotan jarak invers kuadrat.
