New today from Esri, an ocean basemap layer for users of ArcGIS Online. The basemap includes bathymetry, marine water body names, undersea feature names, and derived depth values in meters. Land features include administrative boundaries, cities, inland waters, roads, overlaid on land cover and shaded relief imagery.
The basemap currently provides coverage for the world down to a scale of ~1:1m. U.S. waters have higher resolution bathymetry starting at 1:1m scale; bathymetric data was derived from NOAA survey point data. See more information http://www.gisuser.com/content/view/23822/2/
