NASADEM GLOBAL ELEVATION MODEL: METHODS AND PROGRESS

NASADEM GLOBAL ELEVATION MODEL: METHODS AND PROGRESS

NASADEM is a near-global elevation model that is being produced primarily by completely reprocessing the Shuttle Radar Topography Mission (SRTM) radar data and then merging it with refined ASTER GDEM elevations. The new and improved SRTM elevations in NASADEM result from better vertical control of e...
