| Classification | :term:`Pseudocylindrical Projection` |
| Available forms | Forward and inverse, spherical projection |
| Defined area | Global |
| Alias | hatano |
| Domain | 2D |
| Input type | Geodetic coordinates |
| Output type | Projected coordinates |
proj-string: +proj=hatano
Note
All parameters for the projection are optional.
x &= 0.85\lambda \cos \theta
y &= C_y \sin \theta
P(\theta) &= 2\theta + \sin 2\theta - C_p \sin \phi
P'(\theta) &= 2(1 + \cos 2\theta)
\theta_0 &= 2\phi
| Condition | C_y | C_p |
|---|---|---|
| For \phi > 0 | 1.75859 | 2.67595 |
| For \phi < 0 | 1.93052 | 2.43763 |
For \phi = 0, y \leftarrow 0, and x \leftarrow 0.85\lambda.
