5 days ago · This is a hillshade image of the Himalayas' Mt. Everest-region scanned during the NASA Shuttle Radar Topography Mission (SRTM) in February 2000. SRTM was a payload package flown aboard Space Shuttle Endeavor that included two radars used to create interferograms and near-global topographic maps of Earth called digital elevation models.

Feb 11, 2000 · The Shuttle Radar Topography Mission (SRTM) payload flew aboard the Space Shuttle Endeavour during the STS-99 mission. SRTM collected topographic data over nearly 80% of Earth's land surfaces, creating the first-ever near-global dataset of land elevations.

Mar 1, 2021 · NASA Shuttle Radar Topography Mission V3 Global 1 arc second hillshade image of the Mt Everest region The Land Processes Distributed Active Archive Center ( LP DAAC ) recently released additional tiles in NASA's Shuttle Radar Topography Mission (SRTM) Version 3.0 Global 1 arc second dataset (SRTMGL1), to include coverage over Asia and Australia.

5 days ago · This is a Shuttle Radar Topography Mission (SRTM) hillshade image of the Mount Everest region. SRTM obtained elevation data across nearly 80% of Earth creating the first ever near-global DEM dataset. The data was captured in February 2000 using radar interferometry equipment operating from inside Space Shuttle Endeavour's payload bay.

SRTM topography has become the most popular data set distributed by EDC, with the number of data downloads far exceeding any other remotely sensed data. Since no subsequent global mapping projects are currently planned the SRTM data will remain as the 'definitive' topographic data set for decades to come.

Apr 25, 2024 · On December 16, 2022, the Surface Water and Ocean Topography satellite flew into space aboard a SpaceX Falcon 9 rocket from California's Vandenberg Air Force Base.

Our objective is to provide the scientific and civil communities with a state-of-the-art global digital elevation model (DEM) derived from a combination of Shuttle Radar Topography Mission processing improvements, elevation control, void-filling and merging with data unavailable at the time of the original SRTM production:

The angle between the direction the antenna is pointing and the nadir is the look angle. The angle between the radar beam center and the normal to the local topography is the incidence angle. Both angles are sometimes used synonymously, which is only valid if the SAR geometry is simplified to neglect Earth’s curvature and local topography.

Aug 14, 2024 · After years of pre-launch preparation and 18 months of post-launch effort, all science data products from the Surface Water and Ocean Topography mission are fully validated.
