What's in it

Data offered docs-verified: global elevation for ocean and land, in metres · under-ice topography/bathymetry version for Greenland and Antarctica
Coverage docs-verified: Global
Resolution docs-verified: 15 arc-second grid interval
Formats docs-verified: GeoTIFF (cloud optimised) · STAC item JSON
Access docs-verified: Public; anonymous HTTPS/S3 access via data.source.coop; no API key; licence not stated in docs (see product README and GEBCO terms of use)

Useful for

Use cases llm-inferred: Catchment and site elevation baseline for FRA and drainage strategy assessments where no LiDAR is available · Coastal and offshore bathymetry context for marine or coastal civils scoping · Regional terrain input for flood model boundary and context checks
Audience llm-inferred: flood consultants · drainage engineers · hydrologists · GIS analysts · civils engineers

Limitations

Constraints llm-inferred: 15 arc-second grid is coarse (about 460 m at the equator), so unsuitable for detailed local design · Temporal coverage and update frequency are not stated in the docs · Licence is not stated in the docs; check the product README and GEBCO terms of use · Docs mention a Type Identifier (TID) grid, but no TID file is listed in the product files · Full-file downloads are large (about 3 to 4 GB per GeoTIFF)
