The USGS Digital Elevation Model (DEM) data files are digital representations of elevation information in a raster or grid form. USGS standard one-meter DEMs are produced exclusively from high resolution light detection and ranging (lidar) source data of one-meter or higher resolution. One-meter DEM surfaces are seamless within collection projects, but, not necessarily seamless across projects. 30-Meter SRTM Tile Downloader This interface attempts to ease the pain of downloading 30-meter resolution elevation data from the Shuttle Radar Topography Mission . The resulting data can be directly downloaded and is now (as of 2004) the best available global 1km elevation dataset! Each 7.5-minute DEM is based on 30 by 30 meter data spacing with the Universal Transverse Mercator UTM projection. Since 2001, the USGS Global Visualization Viewer (GloVis) has been available to users for accessing remote sensing data. Name: 3DEPElevation Description: The USGS 3D Elevation Program (3DEP) Bare Earth DEM Dynamic service is based on multi-resolution USGS DEM sources and provides dynamic functions for visualization.
When you click 'Download your data', if the data can be delivered quickly it will be downloaded directly through your browser after a few seconds. I got the VERY messy code that I use to download all Landsat data by setting Path and Row parameters. Users are encouraged to use the Application for Extracting and Exploring Analysis Ready Samples (AppEEARS) web platform as alternatives for transforming and working with ASTER GDEM data. You have no reasonable expectation of privacy regarding any communication transmitted through or data stored on this information system. Like other USGS data, DEMs were produced originally in tiles that correspond to topographic quadrangles. National Aeronautics and Space Administration, National Oceanic and Atmospheric Administration, U.S. Therefore, the CARA relied on a probabilistic methodology of geological analysis and analog modeling. Provides access and links to GIS data for the State of Washington and other selected areas.
If you want to download SRTM data, those data are available at the US Geological Survey's EROS Data Center for download. This web application was developed to display USGS DEM data from the USGS 3D Elevation Program (3DEP). ArcticDEM data is constructed from in-track and cross-track high-resolution (~0.5 meter) imagery acquired by the DigitalGlobe constellation of optical imaging satellites and licensed through the NGA NextView contract.

Click 'View basket' when you are ready to download your data, or to manage the items you have added so far. DEM data for 7.5-minute units correspond to the USGS 7.5-minute topographic quadrangle map series for all of the United States and its territories except Alaska. Summary This is a tiled collection of the 3D Elevation Program (3DEP) and is 1 arc-second (approximately 30 m) resolution.The elevations in this Digital Elevation Model (DEM) represent the topographic bare-earth surface.
Resolution: ~90 m, 3 arc-sec Coverage: Contiguous United States, Hawaii and parts of Alaska Projection: UTM Datum: WGS 72 Vertical Units: Meter A Digital Elevation Model (DEM) consists of a sampled array of elevations for ground positions that are normally at regularly spaced intervals. USGS standard 5-meter DEMs are produced exclusively from interferometric synthetic aperture radar (Ifsar) source data of 5-meter or higher resolution.
Five-meter DEM surfaces are seamless within collection projects, but, not necessarily seamless across projects. Government may monitor, intercept, search, and seize any communication or data transiting, stored on, or traveling to or from this information system. SRTM data was used to update the older USGS GTOPO30 global DEM, by averaging to 30 arc-sec resolution and replacing GTOPO30 heixels between the latitudes of 60° North and 56° South.
