GDEM Black & White Map TIFF - 27MB As of January 2021, the LP DAAC has implemented version 3.0 of the Sensor Information Laboratory Corporation ASTER DEM/Ortho (SILCAST) software, which is used to generate the Level 2 on-demand ASTER Orthorectified and Digital Elevation Model (DEM) products (AST14). For more information about the GDEM, see the Validation Report: ASTER (a) is the original downloaded data, and ASTER 10 was ASTER 30 data that has been performed Neighborhood cell blocks statistic analysis to enhance its resolution up to 10 meter. It is a hybrid product based on SRTM and ASTER GDEM data fused by a weighted averaging approach. GPS Visualizer's map, profile, and conversion programs have the ability to instantly add elevation data from a DEM (digital elevation model) database to any type of GPS file. This dataset is one of the products produced under the 2014-2016 World Bank (WBG) - European Space Agency (ESA) partnership, and is published in the partnership report: Earth Observation for Sustainable Development, June 2016. use via maps api Download data. As mentioned earlier, there are two sets of ASTER DEM data in this study. Due to this wide range the ground resolution depends but ranges from 15 to 90m. A very useful source for world-wide medium resolution (30 m) free DEM data is the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), launched in 1999, which carries 15 channels, with 4 bands at 15 m resolution, 6 at 60m, and 5 at 90m. It is definitely smaller or negligible in Czech Republic (ASTGTM2_N50E014_dem) but the area lacks such strong features as coastlines to tell for sure. AFRICA DEM data for all of Africa can be downloaded via the world coverage map.Without the publication of Aster GDEM version 2, the task of filling the large SRTM desert voids would have taken considerably longer. ASTER GDEM V2 Validation Summary Report. The ASTER GDEM V3 maintains the GeoTIFF format and the same gridding and tile structure as V1 and V2, with 30-meter postings and 1 x 1 degree tiles. This specification documents the requirements and standards used to produce the seamless elevation layers for The National Map of the United States. Releases Enhanced Shuttle Land Elevation Data. ASTER data are used to create detailed maps of surface temperature of land, emissivity, reflectance, and elevation. An additional global product is now available: the ASTER Water Body Dataset (ASTWBD). Version 3 of the ASTER Global Digital Elevation Model (GDEM) provides new features and sharper imagery. Digital Elevation Model (DEM) at 20m and precise DEM at 0.5m for the catchments of Kelani Ganga and Attanagalu Oya. Available DEM sources include SRTM1, SRTM3, NED1, and ASTER. ASTER is one of five instruments aboard NASA’s Terra spacecraft (launched in 1999) and was built in Japan for the Ministry of Economy, Trade, and Industry (METI). The data are provided "as is," 2．Select the area by dragging from the upper left to lower right on the map. Map Name: Layers Legend All Layers and Tables Layers: The ASTER GDEM covers land surfaces between 83°N and 83°S, and was produced through automated processing of 2.3 million scenes from the ASTER archive. In addition, the data are available with transformation services via the LP DAAC’s Application for Extracting and Exploring Analysis Ready Samples (AρρEEARS). Or is that a bug in ASTER GDEM's georeferencing? The GDEM and ASTWBD are available for download from NASA Earthdata and Japan Space Systems. Look at the left corner of the screen, you will see Datasets. (4,320 x 2,160) More recently, higher spatial resolution global DEMs, such as ASTER GDEM (Advanced Spaceborne Thermal Emission and Reflection Radiometer‐Global DEM) [Tachikawa et al., 2011] and AW3D‐DEM (ALOS: Advanced Land Observing Satellite, World 3D‐DEM) [Tadono et al., 2015], have been developed using stereo viewing of optical satellite images. Selected tiles in the area will be highlighted in yellow. The improved GDEM V3 adds additional stereo-pairs, improving coverage and reducing the occurrence of artifacts. ASTER is capable of collecting in-track stereo using nadir- and aft-looking near infrared cameras. In this study, the quality of DEMs acquired by SRTM ver.3 and ASTER ver.2 is evaluated. This ASTER product is available at no charge for any user pursuant to an agreement between METI and NASA. Choose Digital Elevation -> ASTER GLOBAL DEM. U.S. The ASTER DEM was a side product of the ASTER sensor which, on board of the TERRA satellite, takes stunning images of the Earth with 14 different bands ranging from ultraviolet to infrared. The ASTER GDEM was created with two NIR cameras on the ASTER satellite. EU-DEM is a digital surface model (DSM) of EEA member and cooperating countries representing the first surface as illuminated by the sensors. This raster product identifies all water bodies as either ocean, river, or lake. ASTER data is used to create detailed maps of land surface temperature, reflectance and elevation. ... Denotes the angle between the path oriented image and the map oriented image for this ASTER scene. 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.

This ASTER product is available at no charge for any user pursuant to an agreement between METI and NASA. 1．Click button and move the cursor to your download area. TIFF - 27MB ASTER produces images using infrared, red, and green wavelengths of light. Run map on your hardware and in your private cloud, even offline. Below are browse images derived from ASTER GDEM globe map data sets. This raster product identifies all water bodies as either ocean, river, or lake, and each GDEM tile has a corresponding Water Body tile. Image: NASA/METI/AIST/Japan Space Systems, and U.S./Japan ASTER NASADEM is a significant improvement over the available three-arcsecond SRTM DEM primarily because it will provide a global DEM and associated products at one-arcsecond spacing. Earth), moon, or asteroid.A "global DEM" refers to a discrete global grid.DEMs are used often in geographic information systems, and are the most common basis for digitally produced relief maps.. and neither NASA nor METI/Japan Space Systems (J-spacesystems) will be responsible for any damages resulting from use of the data. Enter Search Criteria. Read more about Server. For ASTER GDEM, in each unzipped folder there will be two DEM files: select the one that ends in _dem. TerraLook is a collection of satellite images of areas of conservation interest, packaged with a simple-to-use toolset to find and view them. The Ministry of Economy, Trade, and Industry (METI) of Japan and the United States National Aeronautics and Space Administration (NASA) jointly announced the release of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Order:1) pseudocolor natural color image as WMS/KML; 2) Level 3 orthorectified bands 1-14 with 30m DEM; 3) Global Digital Elevation Model (GDEM). Then uncheck the box beside the DEM and the DEM should disappear. Version 3 of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) is now available from NASA’s Land Processes Distributed Active Archive Center (LP DAAC). PNG - 5MB Values: Valid code: WGS84 File Size How to create a DEM from point data, how to make a 3D visualization and how to get 3D data from USGS Below are browse images derived from ASTER GDEM globe map data sets.
