Map Proyection

Explanation:

Hi, a map projection is one of many methods used to represent the 3-dimensional surface of the earth or other round body on a 2-dimensional plane in cartography (mapmaking). This process is typically, but not necessarily, a mathematical procedure (some methods are graphically based).

It's a system which translates the meridians and parallels network from a curved surface as the Earth globe to a flat surface.
