 ALOS World 3D - 30m has a lot of missing data spots. Shuttle Radar Topography Mission (SRTM GL1) Global 30m seems to have better coverage and the data / heightmap quality is much better than alos world 3d - 30m, it is highly recommended you download SRTM instead.

 You can do [[arma3:terrain:real-world-data-global-mapper#aster_gdem_heightmap|Real World Data Global Mapper]] as it downloads automatically ASTER GDEM data for you if you use the connect to online data button.
+====== US National Elevation Dataset ======
+United States National Elevation Dataset is heightmap with 10 meter resolution which is very good. Unfortunately as the name suggests, its only for America, so unless you are doing american terrain this has no use to you.

+No idea how to download this manually, it can be done using global mapper -> online sources -> U.S. Data -> united states elevation data (NED) (10m resolution).
