Sinusoidal
Name | Sinusoidal |
Model | Pseudo-Cylinder |
Type | Equal Area |
Meridians | Sinusoidal curves, concave toward a straight central meridian |
Parallels | Straight parallel lines |
Spacing Meridian | Equal and decreases toward the poles |
Spacing Parallels | Equal |
Linear Scale | True on the parallels and central meridian |
Specialties | Based on a cylinder tangent at the equator Interruptions are a result of more than one cylinder being applied. A seven zone sinusoidal projection has seven cylinder definitions |
Uses | Allows a world scale map to avoid extreme exaggeration at the poles when used as a multi-zone projection |
Example |
