L'ensemble de données numériques sur l'altitude de la Shuttle Radar Topography Mission (SRTM) a été initialement produit pour fournir des données d'altitude cohérentes et de haute qualité à l'échelle quasi mondiale. Cette version des données d'élévation numérique SRTM a été traitée pour combler les vides de données et faciliter son utilisation.
