# Brief thoughts on map projections

IMO, every map projection that does not have at least one of the following four properties is not very worthwhile.

•

Equal&h;area

•

Conformal

•

Extremely simple to construct from 2D coordinates (latitude and longitude)

•

Extremely simple to construct from 3D coordinates (`x`, `y`, and `z`)

For example:

Property | Cylindrical | Azimuthal | |
---|---|---|---|

Preserves | Area | Cylindrical equal&h;area | Azimuthal equal&h;area |

Shape | Mercator | Stereographic | |

Is extremely simple | In 2D | Equirectangular | Azimuthal equidistant |

In 3D | Central cylindrical | Gnomonic |

Lolsorandom compromise projections can go fuck themselves.
