NASA SRTM Digital Elevation 30m

The Shuttle Radar Topography Mission (SRTM, see [Farr et al. 2007](https://onlinelibrary.wiley.com/doi/10.1029/2005RG000183/full)) 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
