An equirectangular projection is a cylindrical equidistant projection, also called a rectangular projection, plane chart, plate carre, or unprojected map, in which the horizontal coordinate is the longitude and the vertical coordinate is the latitude, so the standard parallel is taken as phi_1=0. The equirectangular projection (also called the geographic projection) is a simple map view made about 100 AD. When it comes to making spherical models or world globes, textures usually be made to have special proportions.
