Additional small ocean islands ranked to two levels of relative importance. Derived from 1:250,000 World Vector Shoreline. Relatively few minor islands shown in polar areas with selective edits elsewhere. Minor islands contain more relative detail than do the islands included with the main 10m ocean coastline data. Ocean bathymetry and ocean polygon are not punched out for minor islands, nor are they included in land polygon or any country or state (admin-0 and admin-1) polygons.
