World NGS Physical Wall Map POSTER-SIZE ENCAPSULATED

The Physical World wall map from the National Geographic Society, size 92 x 61cm (36″ x 24″ approx), encapsulated 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 on paper without the encapsulation.LAMINATED and ENCAPSULATED WALL MAPS:- LAMINATED wall maps have a thin layer of plastic usually applied to the printed side only. They can be written on with suitable marker pens without any damage to the map but, unless laminated on both sides, they are not damp-proof.- ENCAPSULATED wall maps are sealed between two sheets of plastic. They are more rigid and heavier than laminated maps of the same size. They are damp-proof and do not crinkle in humid conditions. Encapsulation gives the map a shiny surface, similar to being displayed behind glass.- PLEASE NOTE: many publishers and retailers often use these two terms interchangeably. Our map titles and descriptions follow the definitions provided above.
