This project is scheduled for completion in 2017, but we expect to release interim products in 2016 and early 2017. 1. View the movie here. 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 data could be visualised in 3D with the Virtual Terrain Software.. SRTM Digital Terrain Model of Germany: Download SRTM Downloader Plugin was developed by Dr. Horst Duester from Sourcepole AG. NASA Shuttle Radar Topography Mission (SRTM) Version 3.0 Global 1 arc second Data Released over Asia and Australia. See the Africa image above and its caption at the PIA04965. 2007) digital elevation data is an international research effort that obtained digital elevation models on a near-global scale. You can create an account at https://urs.earthdata.nasa.gov/. 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 The data could be downloaded under the Open Database License (Timestamp 3/2011).. JPL has released the full SRTM accuracy report. NASA has released a void-filled version of the Shuttle Radar Topography Mission digital elevation model, known as "SRTM Plus" or SRTM NASA Version 3. Radar Image with Color Wrapped Fringes. Geophys., 45, RG2004, doi:10.1029/2005RG000183" was recently released. Integer heights in the merged void-free DEM files are relative to the EGM96 geoid (whereas the floating-point heights in the SRTM-only DEM files are relative to the WGS84 ellipsoid). Changes in color signify changes in height. This interface attempts to ease the pain of downloading 30-meter resolution elevation data from the Shuttle Radar Topography Mission. Click on yellow tiles to download their corresponding data. 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). A National Imagery and Mapping Agency (NIMA) e a National Aeronautics and Space Administration (NASA) foram as instituições responsáveis pela missão SRTM. The Shuttle Radar Topography Mission (SRTM) (Wikipedia article) is a NASA mission conducted in 2000 to obtain elevation data for most of the world.It is the current dataset of choice for digital elevation model (DEM) data since it has a fairly high resolution (1 arc-second, or around 25 meters), has near-global coverage (from 56°S to 60°N), and is in the public domain. SRTMGL1 coverage now includes Africa, Europe, North America, South America, Asia, and Australia in 1° X 1° tiles at 1 arc second (about 30 meters) resolution. The colored regions of this map show the extent of digital elevation data recently released by the Shuttle Radar Topography Mission (SRTM). It carried in its loading bay SIR-C (NASA) and X-SAR Enter Search Criteria. This processor transformed the radar echoes into strips of digital elevation data – one strip for each of the 1,000 or so data swaths. The Shuttle Radar Topography Mission (SRTM, see Farr et al. https://lpdaac.usgs.gov/products/measures_products_table. num: Class: 0 255 30 meters Index indicating the data source and the number of source scenes. For further information, contact LP DAAC User Services. SRTM obtained elevation data on a near-global scale using radar interferometry. ASTER is a sensor on NASA's Terra satellite that uses stereoscopic imaging to measure elevations via optical parallax where not obscured by clouds. In February 2000, Space Shuttle Endeavour started on an 11-day SRTM (Shuttle Radar Topography Mission) remote sensing mission. The SRTM radar contained two types of antenna panels, C-band and X-band. SRTM Plus uses SRTM Version 2 (see below) where the radar interferometric method was successful (not void). This coincides with the newly processed areas released by the United States Geological Survey (USGS) on January 2, 2015 available through EarthExplorer. A NASA Earthdata login is required to download the files. Overview Download Data Services Tools Citation Information Documentation Additional Information Since then the schedule was accelerated, and all global SRTM data have been released. [Summary provided by NASA.] 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 The Version 2 directory also contains the vector coastline mask derived by NGA during the editing, called the SRTM Water Body Data (SWBD), in ESRI Shapefile format. (SRTM did not produce data for the northernmost latitudes or Antarctica.). The Version 2 directory also contains the vector coastline mask derived by NGA during the editing, called the SRTM Water Body Data (SWBD), in ESRI Shapefile format. Since no subsequent global mapping projects are currently planned the SRTM data will remain as the 'definitive' topographic data set for decades to come. 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). The near-global topographic maps of Earth called Digital Elevation Models (DEMs) are … 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). As with SRTM Plus, this work is funded under NASA's "Making Earth System Data Records for Use in Research Environments" (MEaSUREs) Program. 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. It can be accessed (as "SRTM-4" within that issue) at: http://www.asprs.org/Photogrammetric-Engineering-and-Remote-Sensing/PE-RS-Journals.html. It is available in at the following versions: 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. Version 1.0: SRTM radar echo data were processed in a systematic fashion using the SRTM Ground Data Processing System (GDPS) supercomputer system at the NASA Jet Propulsion Laboratory. This release includes data for most of Europe and Asia plus numerous islands in the Indian and Pacific Oceans. 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. Indonesia, with many volcanoes, starting at Bali, flying westward over Java, and ending at Krakatoa (Pulau Krakatau). 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 USGS SRTM data is based on NASA's SIR-C instrument. The NASA Shuttle Radar Topographic Mission (SRTM) has provided digital elevation data (DEMs) for over 80% of the globe. 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 … The data are available for download via Earthdata Search, the LP DAAC Data Pool and the Global Data Explorer (GDEx). The SRTM data will be dowloaded from NASA Earth Data server. In brief, the expected improvements include (1) fine vertical adjustments within and among individual shuttle data takes via reference to precise ICESat (Ice, Cloud, and land satellite) laser profiles, (2) void reduction via improved radar interferometric processing, (3) use of better fill data in the remaining voids, especially ASTER GDEM3 when available, and (4) improved quality assessments and adjustments. SRTM Plus elevation models and related products are available from NASA's Land Processes Distributed Active Archive Center (LPDAAC) at: Over 50 different global datasets are represented with daily, weekly, and monthly snapshots, and images are available in a variety of formats. 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. 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. Additional void filling of small areas used the GMTED2010 elevation model compiled by the US Geological Survey. Shuttle Radar Topography Mission fait référence à des fichiers matriciels et vectoriels topographiques fournis par deux agences américaines : la NASA et la NGA (ex-NIMA). 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. This fly around uses only SRTM data, shaded and with colored height. 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. If you want to download SRTM data, those data are available at the US Geological Survey's EROS Data Center for download. This data is currently distributed free of charge by USGS and is available for download from the National Map Seamless Data Distribution System, or the USGS ftp site. 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. SRTM collected an unprecedented 8.6 Terabytes of interferometric C-band Synthetic Aperture Radar (SAR) data (equivalent to about 14,317 CDs).
