Description / Specifications

UWP Typical Format

Name	Hex	Physical Stats	Base Code	Trade Classifications	Extended Stats	Allegiance Code
Roup	0407	C77A9A9-6	S	Hi In Wa	A323	Im

Thus the planet Roup is located in hex 0407 in the sector, it has physical stats of C77A9A9-6, a base code of S(cout) and has trade classification of "Hi In Wa", the extended data is A323, and has allegiance to the Im(perium).

The extended stats include:

• A (amber): Travel Zone
• 3: Population Multiplier
• 2: Planetoid Belts
• 3: Gas Giants

Basic UWP Stats

Physical Stats:

• Starport

SAH Sequence:

• Planetary Size
• Atmosphere
• Hydrosphere

PGL Sequence:

• Population
• Government
• Law level

TL:

• Tech level

UWP Format Dictionary

#	Category	Explanation	Remarks
1.	Starport	A Starport is an establishment for the landing, servicing, refueling, launching, and control of starships. Starports range in quality from A (the best and most extensive) to E (the worst, little more than a spot of cleared ground), and X. A secondary set of spaceport ratings includes F, G, H, and Y.	Stand-alone qualifier.
2.	Size	Worlds are classified according to their physical size (Planetary Size). Only Mainworlds (worlds or planets) of interest are recorded. Planetary size and density are the two strongest indicators of surface gravity parameters. e.g. Gas Giants are simply classified as Small (SGG) or Large (LGG).	Part of SAH sequence.
3.	Atmosphere	The Atmosphere code is a UWP code to represent the breathing environment encountered on the world. It represents the mixture of gases and other elements that may be present on a world (planet). Atmosphere greatly affects the habitability of a world.	Part of SAH sequence.
4.	Hydrographics	The Hydrosphere represents (Hydrographics) or the liquid content of a world, usually water on a conventional life-supporting world (planet). For normal worlds, the hydrosphere will be water; on other worlds with exotic, corrosive, or insidious atmospheres, it may be other liquids or fluids such as ammonia.	Part of SAH sequence.
5.	Population	The Population UWP code is an indicator of the world's population of Sophonts. This figure represents the exponent (number of zeros) which follow the first population digit (this digit is outlined in the extended data). High Population worlds are generally shown in all caps (e.g. ROUP) on sector/subsector maps.	Part of PGL sequence.
6.	Government	Government is the method by which a subplanetary (...smaller than a world), planetary (world), or interstellar (multi-system) state or community, leads (governs) itself. Standard UWP codes exist to explain most of the most common government types. The study of governments, governance, and other related subjects is known as political science, a type of social science.	Part of PGL sequence.
7.	Law level	Law Level is an indication of the relative oppressiveness of the world (planet) of whom the law serves more: the inhabitants (...and visitors) [distributed power] or the government and politicians of a planet (...or polity) [centralized power]. The more centralized or autocratic a government (polity) is, the more likely the higher laws codes will be more oppressive. The less centralized or more distributed a government (polity) is, the more likely the lower laws codes will be more democratic.	Part of PGL sequence.
8.	Tech level	Technology Level or Tech Level, commonly abbreviated TL, is a measure of technological capability. Usually this is used in the Universal world profile to indicate the overall technology of the planet. A planet may have large sections, and/or populations at a more primitive or advanced level than listed.	Stand-alone qualifier.
