-This tutorial covers single raster heightmap as per the kind you will find on opentopo [[http://opentopo.sdsc.edu/raster?opentopoID=OTSRTM.082015.4326.1|here]], I will detail steps for heightmaps spread across muliptle rasters in another update. as they will require additional steps likely including Merge / Build Virtual Raster commands. This section does not cover any re scaling of heightmap, which I would recommend against anyway. Remember [[https://pmc.editing.wiki/doku.php?id=arma:terrain:grid_cell_size|Grid size x Cell size]] should = the same size (meters) as your source heightmap selection.+This tutorial covers single raster heightmap as per the kind you will find on [[https://portal.opentopography.org/raster?opentopoID=OTSRTM.082015.4326.1|opentopo]], I will detail steps for heightmaps spread across multiple rasters in another update. as they will require additional steps likely including Merge / Build Virtual Raster commands.
