Planetary Designation System

The Planetary Designation System (or PDS) is the classification system used by the Human Imperial Alliance to classify the wide variety of planets that are in it's borders. The Exploratory Force, when it first finds a new planet, will often be the one to apply the first classifications to a world, although they can change as a planet experiences war, urbanization, or desertion. In the PDS, each world will receive one of the many classifications.

Urbanized World-
A planet covered mostly in cities, with many factories that operate day and night. Cities are built to hold as many people as possible, resulting in massive towers connected on many floors by bridges between the buildings. Conditions vary wildly, but generally, the wealthy live at the top, and wealth decreases as you go down the floors. The cities themselves are miles high, and require a complex system of oxygen generators, water pumps, and electrical systems to ensure that riots do not happen in the lower levels, where the police are often not able or willing to venture down to, as the people who remain in those shadowy areas are quite dangerous. The cities mainly provide workers for the factories often located outside cities, as well as soldiers from the lower classes, in which joining the the Planetary Defense Force is often their only chance at a better life. With natural resources on Urbanized Worlds all but gone, they rely on the Imperial Logistics Corp to provide food and raw materials.

Assembly World-
Assembly worlds are mostly covered in massive factories, and are very important to the Human Imperial Alliance's military machine as well as it's civilians, who get their goods from these planets. The massive factories that operate on these planets require a large population, so there are large cities, similar to the ones located on Urbanized worlds. On many Assembly Worlds there are also large schools that educate the wealthier children of the population to become scientists who will develop new weapons, vehicles, or manufacturing methods to be used or created on the planet. In orbit around larger Assembly worlds is a large shipyard, which builds and repairs the military and commercial ships of the Human Imperial Alliance. Needing massive amounts of raw materials to fuel its foundries, Assembly worlds are often located in the same system as a Mineral World, or will have one as a moon.
