Topography. Find Data. The general configuration of the land surface, including its relief and the position of its natural features. Definition source: GISGeography.
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. The SRTM payload consisted of two radar antennas, one located in the shuttle's payload ...
Apr 25, 2024 · On December 16, 2022, the Surface Water and Ocean Topography (SWOT) satellite flew into space aboard a SpaceX Falcon 9 rocket from California's Vandenberg Air Force Base. Jointly developed by NASA and CNES (Centre National D'Études Spatiales), with contributions from CSA (Canadian Space Agency) and the United Kingdom Space Agency (UKSA), SWOT ...

Apr 22, 2014 · Bathymetry/Seafloor Topography. Find Data. The measurement and charting of the spatial variation of the ocean depths. Definition source: National Oceanic and Atmospheric Administration.
Feb 18, 2020 · 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. Its improvement and augmentation by ...
Aug 14, 2024 · Sea Surface Height. Find Data. The height of the ocean surface above a datum, such as a vertical datum for sea level measurements, or a reference ellipsoid for satellite altimetric measurements. Definition source: National Aeronautics and Space Administration.
Mar 20, 2024 · SWOT Webinar slides 3.20.24.pdf (PDF, 7.86 MB) Top image: First global image of sea surface height (SSH) anomalies acquired by SWOT over its 21-day repeat cycle (July 26 to August 16, 2023) at scales below 2,000 kilometers. High SSH values are in red and low SSH values are in blue. Lower image: Earth's global rivers as seen by SWOT indicated in ...
Mar 17, 2023 · SWOT is a joint NASA/Centre National d'Etudes Spatiales (CNES, the French space agency) mission, with contributions from the Canadian and United Kingdom space agencies, to globally survey the topography of Earth's ocean and the elevation of surface waters, such as lakes, rivers, and wetlands. Data are collected using radar interferometry ...
