AI-generated Key Takeaways
-
The SRTM digital elevation data, a NASA JPL product, provides near-global elevation models at a 1 arc-second (30m) resolution.
-
This SRTM V3 (SRTM Plus) dataset has been void-filled using open-source data (ASTER GDEM2, GMTED2010, and NED).

Description
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).
This dataset has undergone a void-filling process using open-source data (ASTER GDEM2, GMTED2010, and NED), as opposed to other versions that contain voids or have been void-filled with commercial sources. For more information on the different versions see the SRTM Quick Guide.
