The GEBCO_2021 Grid, a continuous terrain model for oceans and land at 15 arc-second intervals
The GEBCO_2021 Grid - a continuous terrain model for oceans and land at 15 arc-second intervals. The GEBCO_2021 Grid is a continuous, global terrain model for ocean and land with a spatial resolution of 15 arc seconds.The grid uses as a 'base-map' Version 2.2 of the SRTM15+ data set (Tozer et al, 2019). This data set is a fusion of land topography with measured and estimated seafloor topography. It is augmented with gridded bathymetric data sets developed as part of the Nippon Foundation-GEBCO Seabed 2030 Project.
