GENERAL KNOWLEDGE

Detailed explanation-1: -A map projection is a mathematically described technique of how to represent the Earth’s curved surface on a flat map. To represent parts of the surface of the Earth on a flat paper map or on a computer screen, the curved horizontal reference surface must be mapped onto the 2D mapping plane.

Detailed explanation-2: -A map projection is any of many methods used in cartography (mapmaking) to represent the two-dimensional curved surface of the earth or other body on a plane.

Detailed explanation-3: -The top figure, called the equi-rectangular projection is perhaps the simplest of all map projections; its formula is T(, )=(, ). The other is Lambert’s equal area cylindrical projection; its formula is T(, )=(, sin()).

Detailed explanation-4: -A projection is a way to represent Earth’s curved surface on flat paper (Figure below). A map projection translates Earth’s curved surface onto two dimensions. There are many types of projections.
