Lambert cylindrical equal-area projection of the world.
Lambert cylindrical equal-area projection of the world, central meridian at 160°W to focus the map on the oceans.
How the Earth is projected onto a cylinder
In cartography, the Lambert cylindrical equal-area projection, or Lambert cylindrical projection, is a cylindrical, equal area map projection. It is a member of the cylindrical equal-area projection family. This projection is undistorted along the equator, which is its standard parallel, but distortion increases rapidly towards the poles. Like any cylindrical projection, it stretches parallels increasingly away from the equator. The poles accrue infinite distortion, becoming lines instead of points.
The projection is attributed to the Alsatian mathematician Johann Heinrich Lambert in 1772.
