This beautiful view of the Earth is a 1 arc-minute global relief model of Earth's surface that integrates land topography and ocean bathymetry. An arc-minute is 1/60 of a degree. Scientists use high resolution maps like this to improve accuracy in tsunami forecasting, modeling, and warnings, and also to enhance ocean circulation modeling and Earth visualization.
