What is SRTM model?

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 used for?

USGS EROS Archive – Digital Elevation – Shuttle Radar Topography Mission (SRTM) Non-Void Filled. Shuttle Radar Topography Mission data were used to generate digital elevation data with a resolution of 1 arc-second for the United States and 3 arc-seconds for global coverage.

Is SRTM accurate?

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 do I get SRTM?

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 .

How accurate is USGS elevation data?

As of 2022, the absolute vertical accuracy of the 3D Elevation Program (3DEP) 1/3 arc-second seamless DEM product within the conterminous United States is approximately 0.82 meters root mean square error (RMSE), based on a comparison to almost 25,000 NOAA National Geodetic Survey OPUS points.

What is SRTM 30?

The Shuttle Radar Topography Mission (SRTM, see Farr et al. 2007) digital elevation data is an international research effort that obtained digital elevation models on a near-global scale. This SRTM V3 product (SRTM Plus) is provided by NASA JPL at a resolution of 1 arc-second (approximately 30m).

Does SRTM include buildings?

When using SRTM data with TAP land-mobile rf coverage studies, since the SRTM data already includes building or vegetation heights, the use of Surface Feature files is usually not necessary.
