Service Description: A grayscale shaded relief visualization of the General Bathymetric Chart of the Oceans GEBCO_2023 grid, combined with generalized land cover coloration from the Natural Earth 1 dataset.

The Natural Earth 1 imagery and lake polygons were obtained from https://naturalearthdata.com. The coastline displayed is from Esri's World Countries dataset.

Please also see NOAA/NCEI's layer of GEBCO_2023 bathymetric contours.

A color version is also available, and see here for a map with both hillshade and contours included.
