Planetary Grid

The Planetary Grid is a method of mapping out planets in a logical fashion, 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.
