Model digital permukaan (DSM) dan medan (DTM) yang berasal dari data LiDAR NEON. DSM: Fitur permukaan (informasi topografi dengan vegetasi dan struktur buatan manusia). DTM: Ketinggian permukaan tanah
(informasi topografi dengan vegetasi dan struktur buatan manusia yang dihapus). Gambar diberikan dalam meter di atas permukaan laut rata-rata dan digabungkan ke dalam petak yang seragam secara spasial pada resolusi 1 m. Ketersediaan di GEE mungkin tidak mewakili ketersediaan penuh di NEON Data Portal (ditautkan di bawah). Situs dan tahun tambahan dapat ditambahkan ke GEE berdasarkan permintaan
dengan mengirim email ke listaopgee@battelleecology.org.
