Latitude and Longitude are angles from a standard location. The map lines are named Meridian (North-South) and Circles of latitude (East-West). Following a meridian at 0 degrees N-S, through Greenwich GMT, follows all positions having 0 degrees Longitude. Following a circle of latitude along the Equator E-W follows all positions have 0 degrees Latitude. By convenion a fixed point is given as: (lat,lon)

note result of latex here is: . so if you ?text? cut and paste you can get the latex source

note dispSFinmath disables ams math fonts. note wiki ignores AMS Latex hit or miss if supp, ie \hspace{n m}. some of the most essential are damage: \[ line \] and \vert/\alpha/ are "missing", so is \newcommand.

in totality: maybe they have a convenient way to upload this, most will be left with an onerous task. no editor is likely to support saving wiki flavor (gee, imagine).
