Les données numériques d'altitude de la Shuttle Radar Topography Mission (SRTM, voir Farr et al. 2007) sont le fruit d'une initiative de recherche internationale qui a permis d'obtenir des modèles numériques d'altitude à l'échelle quasi mondiale. Ce produit SRTM V3 (SRTM Plus) est fourni par le JPL de la NASA avec une résolution de 1 seconde d'arc (environ 30 m).
Cet ensemble de données a été soumis à un processus de remplissage des vides à l'aide de données Open Source (ASTER GDEM2, GMTED2010 et NED), contrairement à d'autres versions qui contiennent des vides ou ont été remplies avec des sources commerciales.
Pour en savoir plus sur les différentes versions, consultez le Guide rapide SRTM.
Sauf indication contraire, les images et les vidéos sur les sites Web publics du JPL (sites publics se terminant par une adresse jpl.nasa.gov) peuvent être utilisées à n'importe quelle fin sans autorisation préalable. Pour en savoir plus et connaître les exceptions, consultez le site sur les règles d'utilisation des images du JPL.
