Planetary grid

The planetary grid is a method of mapping out planets logically, with a latitude and longitude, into rectangular divisions. Planetary Grids are numbered by the UNSC, with two coordinates. The coordinates correspond to the grid on a two-dimensional map. Each planet has a Grid of its own, with unique features.
