This also includes additional code not covered in the video, and will be updated through time. The Data The ETOPO Global Relief Model integrates topography, bathymetry, and shoreline data from regional and global datasets to enable comprehensive, high-resolution renderings of the Earth's geophysical characteristics. It supports applications such as: Tsunami forecasting, modeling, and warning. Ocean circulation modeling. Earth surface visualisation.
