Question
How is the area kept equal in cylindrical equal-area projection?
Solution
The cylindrical equal-area projection has been derived by projecting the surface of the globe with parallel rays on a cylinder touching it at the equator. Both the parallels and meridians are projected as straight lines intersecting one another at right angles. The pole is shown with a parallel equal to the equator; hence, the shape of the area gets highly distorted at a higher latitude.
