SRTM V2 Released The data may be obtained through this URL: and go to the directory where both version 1 and version 2 directories may be found. Please read the appropriate documentation, also found in the directories.
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.
What resolution is SRTM data?
1 arc-second
The resolution for SRTM Void Filled data is 1 arc-second for the United States and 3 arc-seconds for global coverage.
What is SRTM DEM data?
The Shuttle Radar Topography Mission (SRTM) is an international research effort that obtained digital elevation models on a near-global scale from 56°S to 60°N, to generate the most complete high-resolution digital topographic database of Earth prior to the release of the ASTER GDEM in 2009.
What is SRTM elevation data?
The Shuttle Radar Topography Mission (SRTM) database contains global elevation data with 3 arc-second (90 m) spatial resolution. GIS software, commercial or public-access, is needed for data visualization and further processing or combination with other spatial datasets.
How does ArcGIS process SRTM data?
SRTM PROCESSING-ArcGIS
- Download the area of interest:
- Unzip the elevation file in a new sub-directory. a. Ex. D:\raw\SRTM\new.
- Open a command prompt. a. Start > Run > type ‘cmd’ and press enter. b. Navigate to \raw\SRTM\new\ c.
- Edit the textfile in excel to add variables for our batchfile.
Is SRTM bare earth?
We develop the first global ‘Bare-Earth’ Digital Elevation Model (DEM) based on the Shuttle Radar Topography Mission (SRTM) for all landmasses between 60N and 54S. Therefore, our DEM will be valuable for any global applications, such as large scale flood modelling requiring a ‘Bare-Earth’ DEM.
How accurate are elevations in Google Earth?
The accuracy of SRTM Data can range from 5 to 10 meter, depending on where you are.
What is the use of SRTM data?
SRTM DEM has been successfully used in geological studies. The popular method is merging multi-source remote sensing images, such as high-resolution images with low-resolution images or optical images with radar images, to generate a fused image which combines the advantages of different images.
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).
How do I open a SRTM file in ArcGIS?
How do I use DEM data in ArcGIS?
DEMs stored as point shapefiles
- Add your DEM point dataset to your map document. Open up the Layer Properties window and click on the Source tab.
- In ArcToolbox, expand Conversion Tools, then To Raster, and double-click on Point to Raster.
- The resulting raster dataset will automatically be added to your map document.
