- The Australian National University's Shuttle Radar Topography Mission (ASTER) Global Elevation Model (GDEM) Version 3 (ASTGM) elevation dataset was selected because it provided a 12 Maps of the Past Climate of Vanuatu consistent coverage across Vanuatu at an acceptable spatial resolution of 1 arc second (approximately 30-metre) and was freely available via the Vanuatu Environment Data Portal
