World NGS Physical Wall Map POSTER-SIZE PAPER
The Physical World wall map from the National Geographic Society, size 92 x 61cm (36″ x 24″ approx), paper version, designed to show not only the physical features of the land masses but also to provide a superb representation of the ocean floor.Altitude colouring and subtle but effective relief shading are used to show the topography of the land masses, with plenty of names of mountain ranges, plateaux, deserts, plains, etc. Also marked are the sources of important rivers such as the Amazon, the Nile or the Volga. No country names or boundaries are indicated and only selected major cities are marked.The sea floor is drawn with great skill to achieve a 3-D effect; continental shelves, trenches, ridges and fractures, plains, basins, etc, are shown with their names.Elevation on land is given in feet only, soundings are in metres. The map has latitude and longitude lines drawn at 10ยฐ intervals. Projection is Winkel Tripel.The two Polar Regions are presented as insets in the top corners, while at the bottom are maps of the world showing the tectonic plates and locations of major earthquakes, plus the world’s climatic zones and ocean currents.This title is also available encapsulated.
