SRTM15_PLUS Estimated Topography, 15 seconds, Global, v1

Description

One GMT file, topo15.grd, with the entire global topography. The grid resolution is 15 seconds which is roughly 0.27km at the equator. The data are pixel registered. Land data are based on the 1-km averages of topography derived from the USGS SRTM30 grided DEM data product created with data from the NASA Shuttle Radar Topography Mission (https://www2.jpl.nasa.gov/srtm/). GTOPO30 data (http://www1.gsi.go.jp/geowww/globalmap-gsi/gtopo30/gtopo30.html) are used for high latitudes where SRTM data are not available. Ocean data are based on the Smith and Sandwell global 1-minute grid (https://topex.ucsd.edu/WWW_html/mar_topo.html) between latitudes +/-81 degrees. Higher resolution grids have been added from the LDEO Ridge Multibeam Synthesis Project ( https://www.gmrt.org/ ), the JAMSTEC Data Site for Research Cruises (https://www.godac.jamstec.go.jp/darwin/e), and the NGDC Coastal Relief Model (https://www.ngdc.noaa.gov/mgg/coastal/coastal.html). Arctic bathymetry is from the International Bathymetric Chart of the Oceans (IBCAO) (https://www.ngdc.noaa.gov/mgg/bathymetry/arctic/arctic.html) [Jakobsson et al., 2003]. Matching files of source identification number are available for determining the data source for every pixel.
