I dati digitali di elevazione della Shuttle Radar Topography Mission (SRTM, vedi Farr
et al. 2007) sono il risultato di un'iniziativa di ricerca internazionale che
ha ottenuto modelli digitali di elevazione su scala quasi globale. Questo
prodotto SRTM V3 (SRTM Plus) è fornito dal NASA JPL
con una risoluzione di 1 secondo d'arco (circa 30 m).
Questo set di dati è stato sottoposto a un processo di riempimento dei vuoti utilizzando dati open source
(ASTER GDEM2, GMTED2010 e NED), a differenza di altre versioni che
contengono vuoti o sono state riempite con fonti commerciali.
Per ulteriori informazioni sulle diverse versioni, consulta la
guida rapida SRTM.
Se non diversamente indicato, le immagini e i video sui siti web pubblici del JPL (siti pubblici che terminano con un indirizzo jpl.nasa.gov) possono essere utilizzati per qualsiasi scopo senza previa autorizzazione. Per ulteriori informazioni
ed eccezioni, visita il sito delle norme di utilizzo delle immagini del JPL.
