Description
This projection is an equal-area cylindrical projection suitable for world mapping.
Projection method
Cylindrical—standard parallels are at 30° N and S (a case of Cylindrical Equal Area).
Lines of contact
The two parallels at 30° N and S.
Linear graticules
Meridians and parallels are linear.
Properties
Shape
Shape distortion is minimized near the standard parallels. Shapes are distorted north–south between the standard parallels and distorted east–west above 30° N and below 30° S.
Area
Area is maintained.
Direction
Directions are generally distorted.
Distance
Distances are generally distorted except along the equator.
Limitations
Useful for world maps only.
Uses and applications
Only useful for world maps.
