Release of NASADEM Data Products

February 13, 2020
By: LP DAAC

The LP DAAC is pleased to announce the availability of NASADEM data products at 1 arc second resolution.

NASADEM extends the legacy of the Shuttle Radar Topography Mission (SRTM) by improving the digital elevation model (DEM) height accuracy and data coverage as well as providing additional SRTM radar-related data products. The improvements were achieved by reprocessing the original SRTM radar signal data and telemetry data with updated algorithms and auxiliary data not available at the time of the original SRTM processing.

A citation containing the Digital Object Identifier (DOI) for each of the GEDI datasets is provided below.
