World Bathymetry Base Map with Ocean and Natural Features

World Bathymetry Base Map WMTS is a tile cache service providing global bathymetry and ocean data. The Australian Ocean Data Network compiled the information from sources including Natural Earth and the National Geophysical Data Center's ETOPO2 Global 2 Elevations from September 2001. The service includes layer scale dependencies.

Use Cases

• Create marine navigation charts based on global bathymetry data.
• Analyze ocean floor topography for geological research based on elevation data.
• Generate thematic maps for environmental studies based on natural and population features.
• Serve as a base layer for GIS applications requiring country boundaries and ocean data.

Strengths

• Derived from authoritative sources including Natural Earth and the National Geophysical Data Center.
• Includes multiple thematic layers such as ocean data, country boundaries, population, and natural features.
• Last updated metadata indicates a planned update in 2026-06-17.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The primary elevation source (ETOPO2) is from September 2001, which may be outdated for some applications.
• Row count and specific data scale are unknown, which may limit suitability assessment.
