The dataset is available to download in Geotiff format at a resolution of 3 arc-second (approximately 100m at the equator). The projection is Geographic Coordinate System, WGS84.The value of each grid cell represents its elevation above the sea level (in meters).Filenames: Example - arm_srtm_topo_100m.tif represents SRTM elevation 2000 in ArmeniaData Source: de Ferranti, J., 2017.
