World Terrain & Seafloor 36 X 53

The ocean floor and continental terrain reveal themselves as an interconnected system with the Ridgeline Geographic World Terrain & Seafloor Map. This large wall map is printed on heavyweight matte poster paper at high resolution and shipped in a sturdy cardboard tube to avoid creasing. The print measures 36 inches in vertical height and 53 inches in horizontal length.

Map elements include:

• A stylized and highly detailed digital elevation model of all seven continents. Raw elevation imagery is publicly available for download from the U.S. Geological Survey (USGS).

• A bathymetric model of the world's seafloor, including the Caspian Sea and North American Great Lakes. Similar to continental elevation. Raw bathymetric imagery is publicly available for download from the General Bathymetric Chart of the Oceans (GEBCO).

• A detailed depiction of :

  • Inland water bodies, including intermittent lakes and salt flats

  • Mountain summits with corresponding maximum elevations in feet

  • Terrestrial and submarine volcanoes and volcanic lines/arcs

  • Mountain ranges, plateaus, valleys, and other significant landforms

  • Islands, points, capes, and other coastal features

  • Deserts

  • National and territorial capitals and globally significant cities scaled by population

  • International boundaries

  • Major seafloor features, including ridges, seamount chains, basins, and fracture zones

  • Pinpoint locations of seamounts, guyots, banks, shoals, reefs, and other seafloor prominences

  • Glaciers, ice caps, and ice shelves

    
    

The World Terrain & Seafloor map was the eighth map product completed by Ridgeline Geographic, as the first seven continental maps were used as “building blocks” to gather data and information pertaining to each subject area of the world. These building blocks were then assembled into a single comprehensive world product.

Several "gap" areas required research and mapping, including the southern Pacific Ocean (especially Polynesia and the series of chasms along the seismically active Tonga-Kermadec Line), the southern Kerguelen Plateau, and remote, isolated research outposts in the "Roaring 40s" belt of howling winds within the vast ocean province of the Southern Hemisphere.
