Map Service Name: World_Ocean_Reference
Description: Designed to be used as annotation for features on the World Ocean Base map, this reference layer includes marine water body names, undersea feature names, and derived depth values in meters. Land features include administrative boundaries, cities, and inland water names.
The reference layer was compiled from a variety of best available sources from several data providers, including General Bathymetric Chart of the Oceans GEBCO_08 Grid version 20100927, IHO-IOC GEBCO Gazetteer of Undersea Feature Names August 2010 version (http://www.gebco.net), National Oceanic and Atmospheric Administration (NOAA), and National Geographic for the oceans; and DeLorme, HERE, and Esri for topographic content.
For details on data sources in this map service, view World Ocean Base and Reference Contributors (PDF).
The map currently provides coverage for the world down to a scale of ~1:577k, coverage down to ~1:72k in United States coastal areas and various other areas, and coverage down to ~1:9k in limited regional areas.
The names of the IHO (International Hydrographic Organization), IOC (Intergovernmental Oceanographic Commission), GEBCO (General Bathymetric Chart of the Oceans), NERC (Natural Environment Research Council), or BODC (British Oceanographic Data Centre) may not be used in any way to imply, directly or otherwise, endorsement or support of either the Licensee or their mapping system.
