A Map projection means the representation of latitude and longitude of the globe on a flat sheet of paper. The network thus formed is called graticule. Map projection is a mathematical expression using the three-dimensional surface of earth is represented in a two dimensional plane. The process of projection results in distortion of one or more map properties such as shape, size, area or direction.
