Blue Earth Bathymetry is a DEM dataset for studying ocean topography and bathymetry. It provides topographic information on the ocean floor on a global scale, including surface and underwater topographic features of the ocean.

The Blue Earth Bathymetry dataset is an edited version of GEBCO (General Bathymetric Chart of the Oceans), a public domain dataset containing seafloor and land elevation data from around the world.
Because GEBCO comes from different sources and contains some unsightly artifacts, the technicians edited GEBCO to remove some noise and artifacts, making the seabed and land shapes smoother and more natural.

The main application areas of the Blue Earth Bathymetry dataset include marine scientific research, marine geology, marine ecology, marine resource exploration, and marine engineering. It can help scientists and researchers understand the characteristics and changes of ocean topography, explore the structure and function of marine ecosystems, and assess the potential and sustainability of ocean resources.
The resolution is 21600*10800
The goal of Blue Earth Bathymetry is to smooth out the rough edges to facilitate mapping, so Blue Earth's global altitude range is 6,655 to -10,528 meters, lower than Earth's from Mount Everest (8,848 meters) to Challenger Abyss (-10,920 meters) The highest point and the lowest point . The smooth GEBCO dataset shaves off these extreme elevations, especially the tall peaks that occupy little area.
Blue Earth Bathymetry datasets are typically provided as rasters, with each raster cell containing bathymetric information for a specific area. These data can be used to create seafloor topographic maps, perform terrain analysis, simulate ocean processes, and locate and assess ocean and seafloor resources.
To sum up, Blue Earth Bathymetry data is a data set that provides global ocean topography and water depth information, has a wide range of application values, and plays an important role in research in marine science and related fields.
