Where can I download SRTM data?
Where can you download the SRTM data? SRTM DEM data is being housed on the USGS Earth Explorer. To download, select your area of interest. Under the data sets tab, select Digital Elevation > SRTM > SRTM 1-ArcSecond Global .
Is SRTM data free?
On September 23, 2014, the White House announced the coming availability of a near-global 30-meter (m) version of the widely utilized elevation dataset, the Shuttle Radar Topography Mission (SRTM).
What is SRTM 30?
SRTM30 is a near-global digital elevation model (DEM) comprising a combination of data from the Shuttle Radar Topography Mission, flown in February, 2000 and the the U.S. Geological Survey’s GTOPO30 data set. It can be considered to be either an SRTM data set enhanced with GTOPO30, or as an upgrade to GTOPO30.
How do I access SRTM data?
The data may be obtained through this URL: http://dds.cr.usgs.gov/srtm/ and go to the directory where both version 1 and version 2 directories may be found.
How do I download Aster data?
More than 2.95 million scenes of archived data are now available for direct download through the LP DAAC Data Pool and for search and download through NASA’s Earthdata Search Client and NASA’s Reverb. New scenes will be added as they are acquired and archived. Learn more about ASTER data here.
How accurate is SRTM data?
The Shuttle Radar Topography Mission (SRTM) Digital Terrain Elevation Data (DTED) are used with the consensus view that it has a minimum vertical accuracy of 16 m absolute error at 90% confidence (Root Mean Square Error (RMSE) of 9.73 m) world-wide.
How is SRTM data collected?
The Shuttle Radar Topography Mission (SRTM) was flown aboard the space shuttle Endeavour February 11-22, 2000. An antenna located on board the space shuttle collected one data set and the other data set was collected by an antenna located at the end of a 60-meter mast that extended from the shuttle.
What is Ifsar data?
IFSAR stands for Interferometric Synthetic Aperture Radar. Developed just in recent years, IFSAR is a powerful approach in generating high-resolution digital data through the use of Digital Elevation Model (DEM) and an orthorectified radar image.
How do I download ASTER Data for free?
Go to https://earthdata.nasa.gov/ and type ASTER in the search window. You should be able to get all the ASTER data products held in the NASA Land Processes Distributed Active Archive Center which is located at the EROS Center, Sioux Falls, South Dakota, which is a USGS facility. The data are available at no charge.
How to download 30 Meter SRTM elevation data?
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. Click on yellow tilesto download their corresponding data.
How often does SRTM collect land surface data?
SRTM successfully collected radar data over 80% of the Earth’s land surface between 60° north and 56° south latitude with data points posted every 1 arc-second (approximately 30 meters). The level of processing and the resolution of the data will vary by SRTM data set.
Where can I find the SRTM coverage maps?
Coverage Maps indicating the availability of SRTM products are available for download. EarthExplorer can be used to search, preview, and download SRTM Non-Void Filled, SRTM Void Filled, and SRTM 1 Arc-Second Global elevation data. The collections are located under the Digital Elevation category below the SRTM sub-category.
What does SRTM 1 arc-second global mean?
SRTM 1 Arc-Second Global (Digital Object Identifier (DOI) number: /10.5066/F7PR7TFT) elevation data offer worldwide coverage of void filled data at a resolution of 1 arc-second (30 meters) and provide open distribution of this high-resolution global data set. Some tiles may still contain voids.
