It appears that the global 1-arcsecond (30-m) SRTM digital elevation model is now being made publicly available through, for example, the United States Geological Survey's EarthExplorer site (http://earthexplorer.usgs.gov/). Previously the 1-arcsecond-resolution data was only publicly available for the United States. The NASA Shuttle Radar Topographic Mission (SRTM) has provided digital elevation data (DEMs) for over 80% of the globe. 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 SRTM data is available as. The NASA Version 3.0 SRTM Global 1 arc second product is void-filled using elevation data from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model 2 (GDEM2), USGS Global Multi-resolution Terrain Elevation Data (GMTED) 2010, and USGS. There are three resolution outputs available, including 1 kilometer and 90 meter resolutions for the world and a 30 meter resolution for the US. GLCF serves the main USGS editions, plus has 'enhanced' editions as well as provides editions in WRS-2 tiles to approximate Landsat scenes. Sensor and Product Characteristics. Elevation data provides height above the sea level in meters for every single place in the world, measured for regions of approximately 30x30 meters. The original raw open data from US Geological Survey (SRTM 1ARC ), NASA and METI (ASTER GDEM) and European Union (EU-DEM) has been modified, adapted and. Most USGS data is available free, online, at USGS EarthExplorer; You can also browse and directly download some raster data through the National Map Viewer and Download Platform. currently, this is limited to SRTM, NED (National Elevation Dataset), and some small areas of orthoimagery. It helps to familiarize yourself. Many digital elevation models (DEMs) now exist, enabling quantitative assessments of topographic change through DEM subtraction. However, many of these DEMs are inherently different – their source data, preprocessing, and interpolation procedures introduce varying amounts of error, which are partially correlated with. Import grid from USGS SRTM (Shuttle Radar Topography Mission) data. You find data and further information at: http://dds.cr.usgs.gov/srtm/ · http://www.jpl.nasa.gov/srtm/ Farr, T.G., M.

You can use http://www.latlontoelevation.com/ lat/lng to get the Shuttle Radar Topography Mission (SRTM) data too. for want of greater accuracy, but now SRTM data are available at ~30 m resolution for large parts of the world. I therefore present below how to get the data from SRTM or ASTER. SRTM (preferred):. You can get data through the USGS EarthExplorer: http://earthexplorer.usgs.gov/. I haven't had the time to explore much but. The non-public DLR-ASI data is available with a resolution of approximately 30 m (1 arcsec). The most up-to-date version of the 1 km resolution SRTM DEM you can obtain via the USGS website. An updated 1 km resolution global topography map (SRTM30 PLUS; used by Google Earth) has been prepared. The USGS has begun to distribute global Shuttle Radar Topography Mission (SRTM) elevation data at 1 arc-second (~30m) resolution. Previously SRTM data at this resolution have only been available for the US and its territories. These newly released data can refine small-scale modeling and solar. SRTM is probably of better quality than the ASTER GDEM, but lower quality than the 1" USGS NED/GDEP. The biggest problem with SRTM is holes, which occur mostly in two settings: very steep mountains, like the Himalyas, when steep canyons and ridge sides often were not seen by the sensors; and dry.

SRTM-based DEM releases by the National. 104. Geospatial-Intelligence Agency (NGA, former NIMA) are named Digital Terrain Elevation Data (DTED). 105 whereas USGS SRTM releases are simply named SRTM, both followed by a suffix-number, which. 106 indicates the spatial resolution of the DEM. Table 1 summaries. Under an agreement with the National Aeronautics and Space Administration (NASA) and the Department of Defense's National Geospatial Intelligence Agency (NGA), the U.S. Geological Survey (USGS) is now distributing elevation data from the Shuttle Radar Topography Mission (SRTM). The SRTM is a joint project. Land data are based on the 1-km averages of topography derived from the USGS SRTM30 grided DEM data product created with data from the NASA Shuttle Radar Topography Mission. GTOPO30 data are used for high latitudes where SRTM data are not available. Ocean data are based on the Smith and Sandwell global. ... Imagery and Mapping Agency (NIMA) and the National Aeronautics and Space Administration (NASA) in collaboration with the German Aerospace Center (DLR) and the Italian Space Agency (ASI, Agenzia Spaziale Italiana). For more details about SRTM elevation data products, please visit https://lta.cr.usgs.gov/SRTM. There are several sources for digital elevation models such as the Shuttle Radar Topography Mission (SRTM), the USGS National Elevation Dataset (NED), Global DEM (GDEM), and others. Each of these DEMs has pros and cons for their use. Recently, Mapzen has combined several of these sources to. ... States, Hawaii, and Puerto Rico and a resolution of two arc-seconds for Alaska. More info can be found at http://gisdata.usgs.net/NED/. SRTM 30m and SRTM 90m data is also available from the the USGS Seamless Distribution site. Information on the SRTM data can be found at http://srtm.usgs.gov/ . After its release the data will be accessible on EarthExplorer by the US Geological Service (USGS). Unfortunately they didn't announce an exact release date (only “will be released globally over the next year"). That means we have to wait =( Update: Kindly our user Felix Henselowsky asked the USGS for. Ultimately this was achieved by filling the voids with elevation data primarily from the ASTER GDEM2 (Global Digital Elevation Model Version 2) and secondarily from the USGS GMTED2010 elevation model or the USGS National Elevation Dataset (NED). NASA SRTM V3.0 three-arc-second data are provided in two forms:. National Elevation Dataset (NED); National Land Cover Dataset (NLCD) 1992; Shuttle Radar Topography Mission (SRTM); MODIS NDVI Direct Broadcast (7-day satellite image composites). Some areas of the United States are available at 10 meters by 10 meters (100sq meters) while the rest of the country. There are three versions of the official SRTM dataː. Version 1.0 is the (almost) raw data obtained during the mission and its quality is considered research-grade. Data for this version can be downloaded from this USGS directory page. Version 2.1 (aka Non-Void Filled) is the data from Version 1. srtm - A library to load SRTM data and return heights in meter. USGS SRTM FINISHED Data. Q: What is finished topographic data? A: The original SRTM (Shuttle Radar Topography Mission) topographic data (in the .HGT format) contained anomalies, such as spikes or missing elevations.
