The primary goal of the SRTM 30m DEMS is the elimination of voids in the 90m SRTM DEM. 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). Topography Data Download. 2.4. Topography Data Download. Topography metrics (elevation, slope, and aspect) are frequently used as additional source data for image classification along with multi-temporal spectral metrics. To facilitate the image classification applications, the GLAD team provides selected topography metrics in the ARD tile format. Download new SRTM 30 meters. There is a new, 30 meters resolution SRTM DTM coming out…. Download and clip a portion of the SRTM 30m DEM giving bounding box as.
SRTM elevation data is an effort to provide Digital Elevation Model (DEM) at global scope with highest resolution 30 m. Usually the SRTM data can be downloaded from USGS Earth Explorer or NASA Earth Data Server. For this tutorial I'm using QGIS 3.0 master candidate (or QGIS 2.99 exactly) which can be downloaded from QGIS weekly download.
This creates a free and reasonably reliable 3" (90m) Global DEM, free from serious voids and artifacts. The provision of Aster GDEM version 2 by NASA and the Japanese METI has helped to make this possible; despite its many inaccuracies, this source fills the majority of SRTM void areas well enough for the SRTM void cells to be substituted with.
Collection Overview: The Shuttle Radar Topography Mission (SRTM) obtained elevation data on a near-global scale to generate the most complete high-resolution digital topographic database of Earth. SRTM consisted of a specially modified radar system that flew onboard the Space Shuttle Endeavour during an 11-day mission in February of 2000.
This collaboration aims to generate a near-global digital elevation model (DEM) of Earth using radar interferometry. SRTM was the primary (and virtually only) payload on the STS-99 mission of the Space Shuttle Endeavour, which launched February 11, 2000 and ﬂew for 11 days..
SRTM Version 3.0 Global (90m) and United States (30m) Elevation Data Now Available. Apr 8, 2014. The Shuttle Radar Topography Mission (SRTM) obtained 90 meter (3 arc-second) resolution data on a near-global scale (between 56 degrees South and 60 degrees North latitude) and 30 meter (1 arc-second) resolution over United States, providing a.
The Satellite Geodesy research group at Scripps Institution of Oceanography, University of California San Diego studies data collected by radar altimetry and synthetic aperture radar and applies it to geophysical problems.
This data represents the 30 meters Digital Elevation Model (DEM) from Shuttle Radar Topography Mission (SRTM). This data-set was derived through mosaicking of individual SRTM tiles for a particular country and clipping the mosaicked tiles using the country boundary extent. Publication Date April 17, 2015, 3:13 a.m. Type Raster Data Keywords. Digital elevation models (DEM) for the entire globe, covering all of the countries of the world, are available for download on this site. The SRTM 90m DEM’s have a resolution of 90m at the equator, and are provided in mosaiced 5 deg x 5 deg tiles for easy download and use. All are produced from a seamless dataset to allow easy mosaicing. NASA Shuttle Radar Topography Mission V3 Global 1 arc second hillshade image of the Mt Everest regionThe Land Processes Distributed Active Archive Center 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.
The purpose of SRTM was to generate a near-global digital elevation model (DEM) of the Earth using radar interferometry. SRTM was a primary component of the payload on the Space Shuttle Endeavour during its STS-99 mission. Endeavour launched February 11, 2000 and ﬂew for 11 days. The SRTM digital elevation data provided on this site has been processed to fill data voids and to facilitate its ease of use by a wide group of potential users. This data is provided in an effort to promote the use of geospatial science and applications for sustainable development and resource conservation in the developing world.
Digital elevation model (DEM) data was from SRTM (Jarvis, 2008) and was used to investigate the relationship between the spatial agreement of cropland datasets and topography (i.e., elevation and slope). 2.2. Agreement comparison analysis. Free Sample – SRTM (Shuttle Radar Topography Mission) Back Description: The Shuttle Radar Topography Mission (SRTM) data products result from a collaborative mission by the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA), the German space agency (DLR) and Italian space agency (ASI), to generate a near-global digital elevation model (DEM) of.

Download the files from USGS into./data/srtm30m. Before downloading you’ll need to register an account at Using these credentials for downloading is a little tricky, but luckily Earthdata provide download scripts in multiple different languages, the Python ones worked well for me. You want the xxxxxxx.SRTMGL files.
Show activity on this post. There is a new, 30 meters resolution SRTM DTM coming out. As stated on the NASA JPL official page, The next release is planned for later in 2014, and it is expected to include all of South America plus North America south of the United States. It is incomplete, for now, it has only limited coverage.
The newly released data are at one-arc-second pixel size, which is about 30 meters (98 feet), as shown in the right image. The actual resolution of the SRTM DEM varies somewhat but is larger than 50 meters, and is commonly 75 meters or less. In short, the term "resolution" refers to the size of the smallest feature observable in the data.
The Shuttle Radar Topography Mission (SRTM) was flown aboard the space shuttle Endeavour February 11-22, 2000. The National Aeronautics and Space Administration (NASA) and the National Geospatial-Intelligence Agency (NGA) participated in an international project to acquire radar data which were used to create the first near-global set of land. 16 rows.
