World Terrain & Seafloor 36x53
The ocean floor and continental terrain reveal themselves as an interconnected system with the Ridgeline Geographic World Terrain & Seafloor Map, the ultimate physical map of the world. 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 exactly 35.5 inches in vertical height and 52.5 inches in horizontal length.
Map elements include:
A stylized and highly detailed digital elevation model of all seven continents derived from open-source elevation imagery courtesy of the U.S. Geological Survey (USGS).
A bathymetric model of the world's seafloor, including the Caspian Sea, as well as the North American Great Lakes. Bathymetric imagery is derived from publicly-available open-source data courtesy of 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.
