Definitions specific to this category can be found in Definitions/Terrestrial Colatitude.
Let $J$ be a point on Earth's surface that is not one of the two poles $N$ and $S$.
Let $\phi$ denote the latitude of $J$.
The (terrestrial) colatitude of $J$ is the (spherical) angle $90 \degrees - \phi$, that is:
- if $J$ is in the northern hemisphere of Earth, the colatitude is the (spherical) angle $\sphericalangle NOJ$
- if $J$ is in the southern hemisphere of Earth, the colatitude is the (spherical) angle $\sphericalangle SOJ$.
