Global bathymetry and topographic terrain

Cesium World Bathymetry is a global bathymetry and topographic terrain tileset that enables 3D visualizations, simulations, and analytics for use cases like oil and gas exploration, navigation for unmanned undersea vehicles (UUVs), managing offshore wind farms, and analyzing essential climate science. It fuses multiple data sources into a single tileset, including GEBCO's 2023 global dataset, high-resolution bathymetric data around the world, and topographical terrain for inland coverage, enabling you to build applications that span underwater, over land, and in the air.

Terms of use

The Terms of Use include the Cesium ion Terms of Service and the following tileset-specific Terms of Use:

You may not copy, store, or redistribute any portion of the tileset for use in an offline, disconnected, or local environment. Client-side and proxy-based caching are allowed as long as it is a general caching mechanism caching other internet traffic as well, not just Cesium World Bathymetry data.
You must clearly display the attribution for this tileset defined below.
You agree that Cesium World Bathymetry is provided as-is and at-will, and will not hold Cesium GS responsible for anything bad that happens as a result of your use of the tileset or your inability to use the tileset.
You agree that these terms of use may change at any time, and that your continued use of the tileset constitutes acceptance of the new terms.

Attribution

Cesium 3D engines automatically display attribution. Do not remove or modify it.

When using Cesium World Bathymetry outside of a Cesium 3D engine, you must clearly display the Cesium ion logo in the application’s window and include the following source data attributions:
