This dataset shows the global distribution of coral reefs in tropical and subtropical regions. It is the most comprehensive global dataset of warm-water coral reefs to date, acting as a foundation baseline map for future, more detailed, work. This dataset was compiled from a number of sources by UNEP World Conservation Monitoring Centre (UNEP-WCMC) and the WorldFish Centre, in collaboration with WRI (World Resources Institute) and TNC (The Nature Conservancy).
The GEBCO_2019 Grid is a global grid of elevation data at 15 arc-second intervals. This layer displays the GEBCO_2019 Grid as a shaded relief image showing the shape of the global seafloor. The imagery extends from -180 to 360 in longitude. Please note that the GEBCO_2019, is also available as 2D, flat image in layer GEBCO_2019_Grid_2.
