A globe is a spherical model of Earth, of some other celestial body, or of the celestial sphere. Globes serve purposes similar to maps, but, unlike maps, they do not distort the surface that they portray except to scale it down. A model globe of Earth is called a terrestrial globe. A model globe of the celestial sphere is called a celestial globe.
Physical map of Earth Political map of Earth. A map is a symbolic depiction of interrelationships, commonly spatial, between things within a space. A map may be annotated with text and graphics. Like any graphic, a map may be fixed to paper or other durable media, or may be displayed on a transitory medium such as a computer screen.
Another example is a deep map, or maps that combine geography and storytelling to produce a product with greater information than a two-dimensional image of places, names, and topography. [ 84 ] [ 85 ] This approach offers more inclusive strategies than more traditional cartographic approaches for connecting the complex layers that makeup places.
In cartography, a map projection is any of a broad set of transformations employed to represent the curved two-dimensional surface of a globe on a plane. [1] [2] [3] In a map projection, coordinates, often expressed as latitude and longitude, of locations from the surface of the globe are transformed to coordinates on a plane.
Cosmographiae Introductio ("Introduction to Cosmography"; Saint-Dié, 1507) is a book that was published in 1507 to accompany Martin Waldseemüller's printed globe and wall-map (Universalis Cosmographia). The book and map contain the first mention of the term 'America'.
The map and globe were notable for showing the New World as a continent separate from Asia and for naming the southern landmass America. By April 1507, the map, globe and accompanying book, Introduction to Cosmography, were published. A thousand copies were printed and sold throughout Europe. [10]
The first way is the ratio of the size of the generating globe to the size of the Earth. The generating globe is a conceptual model to which the Earth is shrunk and from which the map is projected. The ratio of the Earth's size to the generating globe's size is called the nominal scale (also called principal scale or representative fraction).
All world maps are based on one of several map projections, or methods of representing a globe on a plane. All projections distort geographic features, distances, and directions in some way. The various map projections that have been developed provide different ways of balancing accuracy and the unavoidable distortion inherent in making world maps.
