See the SRTM Bibliography for further information. The data may be obtained through this URL: http://dds.cr.usgs.gov/srtm/ and go to the directory where both version 1 and version 2 directories may be found. ASTER is a sensor on NASA's Terra satellite that uses stereoscopic imaging to measure elevations via optical parallax where not obscured by clouds. The Shuttle Radar Topography Mission (SRTM, see Farr et al. It's available in the SRTM Bibliography. The image brightness corresponds to the strength of the radar signal reflected from the ground, while colors show the elevation as measured by SRTM. The first release of Shuttle Radar Topography Mission (SRTM) data was provided in 1-degree digital elevation model (DEM) tiles from the USGS FTP server An edited version of "The Shuttle Radar Topography Mission, Rev. The announcement was made at the United Nations Heads of State Climate Summit in New York. 1. Engineers and scientists at JPL are currently working on a complete reprocessing of the original SRTM radar data in order to produce an improved near-global digital elevation model (DEM) to be called NASADEM. The SRTM Water Body Data files are a by-product of the data editing performed by the National Geospatial-Intelligence Agency (NGA) to produce the finished SRTM Digital Terrain Elevation Data Level 2 (DTED® 2). Radar Image with Color Wrapped Fringes. Ces données altimétriques ont été recueillies au cours d'une mission de onze jours en février 2000 par la navette spatiale Endeavour à une altitude de 233 km en utilisant l'interférométrie radar To narrow your search area: type in an address or place name, enter coordinates or click the map to define your search area (for advanced map tools, view the help documentation), and/or choose a date range. Since no subsequent global mapping projects are currently planned the SRTM data will remain as the 'definitive' topographic data set for decades to come. Previously, SRTM data for regions outside the United States were sampled for public release at 3 arc-seconds, which is 1/1200th of a degree of latitude and longitude, or about 90 meters (295 feet). High-resolution topographic data generated from NASA's Shuttle Radar Topography Mission (SRTM) in 2000, previously only available for the United States, will be released globally over the next year, the White House announced today. Its improvement and augmentation by incorporating and combining with other existing NASA topographic data sources would represent a significant enhancement and upgrade in a very cost-effective way. Please read the appropriate documentation, also found in the directories. This is the third release in the series providing access to additional NASA SRTM Version 3.0 Global 1 arc second (SRTMGL1) data coinciding with areas released by the USGS. As with SRTM Plus, this work is funded under NASA's "Making Earth System Data Records for Use in Research Environments" (MEaSUREs) Program. For detailed information regarding SRTM, please see the SRTM User Guide. A Missão Topográfica Radar Shuttle ou Missão Topográfica de Radar Embarcado (acrónimo em inglês SRTM - Shuttle Radar Topography Mission) é uma missão espacial para obter um modelo digital do terreno da zona da Terra entre 56 °S e 60 °N, de modo a gerar uma base completa de cartas topográficas digitais terrestre de alta resolução. The data are available for download via Earthdata Search, the LP DAAC Data Pool and the Global Data Explorer (GDEx). This release includes data for most of Europe and Asia plus numerous islands in the Indian and Pacific Oceans. https://lpdaac.usgs.gov/products/measures_products_table. [Summary provided by NASA.] Additional void filling of small areas used the GMTED2010 elevation model compiled by the US Geological Survey. On September 23, 2014, the White House announced that the highest-resolution topographic data generated from NASA's Shuttle Radar Topography Mission (SRTM) in 2000 was to be released globally by late 2015. The colored regions of this map show the extent of digital elevation data recently released by the Shuttle Radar Topography Mission (SRTM). These additional fly around videos further illustrate SRTM elevation data: India and the Himalaya Mountains, with Landsat satellite images draped over SRTM elevation data. Engineers and scientists at JPL are currently working on a complete reprocessing of the original SRTM radar data in order to produce an improved near-global digital elevation model (DEM) to be called NASADEM. A fly around video of the Crater Highlands of Tanzania, using SRTM elevation data and Landsat images is available at http://www.jpl.nasa.gov/video/details.php?id=1335. 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. It carried in its loading bay SIR-C (NASA) and X-SAR num: Class: 0 255 30 meters Index indicating the data source and the number of source scenes. Therefore you must have an account to download the SRTM elevation data with this plugin. NASA Shuttle Radar Topography Mission (SRTM) datasets result from a collaborative effort by the National Aeronautics and Space Administration (NASA) and the National Geospatial-Intelligence Agency (NGA - previously known as the National Imagery and Mapping Agency, or NIMA), as well as the participation of the German and Italian space agencies. For further information, contact LP DAAC User Services. This interface attempts to ease the pain of downloading 30-meter resolution elevation data from the Shuttle Radar Topography Mission. Indonesia, with many volcanoes, starting at Bali, flying westward over Java, and ending at Krakatoa (Pulau Krakatau). For 11 days in February 2000, the space shuttle Endeavour conducted the Shuttle Radar Topography Mission (SRTM) using C-Band and X-Band interferometric synthetic aperture radars to acquire topographic data over 80% of the Earth's land mass, creating the first-ever near-global data … NASA's Jet Propulsion Laboratory (JPL) performed preliminary processing of SRTM data and forwarded partially finished data directly to NGA for finishing by NGA's contractors and subsequent monthly deliveries to the NGA Digital Products Data Wharehouse (DPDW). SRTM consisted of a specially modified radar system that flew onboard the Space Shuttle Endeavour during an 11-day mission in February of 2000. The Shuttle Radar Topography Mission C-band data for North America and South America are available to the public. Page Last Updated: Mar 1, 2021 at 2:45 PM EST, NASA Shuttle Radar Topography Mission (SRTM) Version 3.0 Global 1 arc second Data Released over Asia and Australia. Most voids are filled with elevation data from the ASTER GDEM2 (Global Digital Elevation Model Version 2). Changes in color signify changes in height. The new data have been released with a 1 arc-second, or about 30 meters (98 feet), sampling that reveals the full resolution of the original measurements. NASA has released version 2 of the Shuttle Radar Topography Mission digital topographic data (also known as the "finished" version). See an index map of the newly available full-resolution data. http://www.jpl.nasa.gov/video/details.php?id=1335, https://lpdaac.usgs.gov/products/measures_products_table, http://www.asprs.org/Photogrammetric-Engineering-and-Remote-Sensing/PE-RS-Journals.html.
