Equirectangular projection
The equirectangular projection (also called the geographic projection) is a simple map view made about 100 AD.[1] The projection maps Longitude and Latitude (vertical and horizontal map lines) to even straight lines. Because the map is stretched out, it can not be used in navigation. Its main use is to show large map areas.

Equirectangular projection of the world; the standard parallel is the equator (plate carrée projection).

Height map of planet Earth at 2km per pixel, including oceanic bathymetry information, normalized as 8-bit grayscale. Because of its easy conversion between x, y pixel information and lat-lon, maps like these are very useful for software map renderings.
