Il Reference Elevation Model of Antarctica (REMA) è un modello digitale di superficie (DSM) dell'Antartide ad alta risoluzione e con timestamp, con risoluzioni spaziali di 2 e 8 metri.
I file DEM a mosaico sono compilati da più strisce che sono state
registrate congiuntamente, unite e sfumate per ridurre gli artefatti di corrispondenza dei bordi.
