The break at the Equator creates a great amount of distortion there. Eckert II is similar to the Eckert I projection. The Eckert I projection has meridians positioned identically to Eckert II, but the Eckert I projection has equidistant parallels.

Construction | Pseudocylinder |

Property | Equal-area |

Meridians | Meridians are straight lines that are equally spaced and broken at the Equator. Central meridian is one half as long as the Equator. |

Parallels | Parallels are straight parallel lines that are unequally spaced. The greatest separation is close to the Equator. Parallels are perpendicular to the central meridian. |

Graticule spacing | See Meridians and Parallels. Pole lines are half the length of the Equator. Symmetry exists at the central meridian or the Equator. |

Linear scale | Scale is true along altitudes 55° 10’ N, and S. Scale is constant along any latitude. |

Uses | To show straight-line equal-area graticule. |
