Trade Map Key
Trade Map Key: This page is a key to the pdf sector trade maps included with some sectors.
- The maps are largely unadorned.
Description (Specifications)
The trade routes are calculated in the following manner:
Trade Map Explanations
- Each world is given a World Trade Number (WTN), a relative ranking of economic influence on outside worlds. It is based upon the world's population and starport. Larger worlds with poor starport facilities have less influence than smaller population worlds with better starports.
- For each pair of worlds a Bilateral Trade Number (BTN) is calculated. This is a ranking of the volume of trade between these two worlds. It takes into account distances, allegiances of the worlds, and other economic factors. The BTN numbers on these maps range from 8 to 12, representing the most active routes.
Each world on the map is placed on a hex grid and given four lines of information.
- 1. First Line: The first line is the Universal World Profile in standard format.
- 2. Second Line: The second line is the world name.
- 3. Third Line: The third line consists of:
- A two or four character Allegiance Code
- A + for a subsector or empire capital or a * for a sector capital world, or blank if neither.
- The count of Gas Giants in the system, typically between 0 and 5
- 4. Fourth Line: The fourth line has a number with four digits These are:
- Digit #1. The world's WTN in e-hex format. The calculated WTN is doubled, as shown in the sector data file.
- Digit #2. The world's incoming and outgoing trade, as a BTN value in e-hex.
- Digit #3. The port's transient trade, as a BTN value in e-hex.
- Digit #4. The size of the port on the world. A log scale value from 0 (the smallest) to 7 (the largest) as generated from GURPS Traveller: Starports pg. 59.
The values of the incoming and transient trade BTN values can be converted back to credit values by looking up the value in the table on pg.16 of GURPS Traveller: Far Trader. As calculated there are no half steps (e.g. BTN 5.5).
Example #1:
- D78A302-A = Universal World Profile or UWP
- Bangwe = World name
- ImDd 2 = Allegiance (Domain of Deneb) + 2 gas giants
- 5083 = WTN (World Trade Number) + Incoming Trade (Imports/Exports) + Port Trade (Transient) + Port size (Starport)
Example #2
- C420774-7 = Universal World Profile or UWP
- Malory = World name
- ImDd 3 = Allegiance (Domain of Deneb) + 3 gas giants
- 8883 = WTN (World Trade Number) + Incoming Trade (Imports/Export) + Port Trade (Transient) + Port size (Starport)
Zoned World Explanations
Some worlds are marked with an amber or red circle.
- The Amber Zone worlds (...or Zhodani Unincorporated Worlds) have some cautionary element to them.
- The Red Zone worlds (...or Zhodani Forbidden Worlds) are forbidden to Traders.
- Trade Routes will avoid these worlds for this reason.
Trade Route Explanations
The trade routes on the map are shown as colored lines, each color representing a trade volume category.
- The trade route colors and their meaning are as follows:
Name | BTN | Remarks | Image |
---|---|---|---|
No Line Routes | (BTN:1-7) | Insignificant Route: If there is no line between two worlds, this means that there isn't enough trade to reach the BTN-8 requirements.
|
None |
Red Line Minor Routes | (BTN-8) | Red Line Minor Route: The red lines represent BTN-8 minor routes.
|
|
Yellow Line Feeder Routes | (BTN-9) | Yellow Line Feeder Route: The yellow lines represent BTN-9 feeder routes.
|
|
Green Line Intermediate Routes | (BTN-10) | Green Line Intermediate Route: The green lines represent BTN-10 intermediate routes.
|
|
Cyan Line Main Routes | (BTN-11) | Cyan Line Main Route: The cyan lines represent BTN-11 main routes.
|
|
Blue Line Major Routes | (BTN-12+) | Blue Line Major Route: The blue lines represent BTN-12+ major routes.

History & Background (Dossier)
The Office of the Emperor, the Imperial Bureaucracy, the Imperial Interstellar Scout Service, the Travellers' Aid Society, the Merchant Service, the Educational Institutes, and many other interstellar organizations use this data for governance, interstellar economy, world surveys, and other necessary tasks.
Such data drives Charted Space.
Sector Economic Data Key
The trade generation system also calculates a number of additional data points for each world. This data is stored with each sector under the <sector page>/economic page.
The columns of the data files and their meanings are as follow:
Term | Remarks |
---|---|
Hex | Position in the sector |
Name | Name of the world |
UWP | Universal World Profile - Basic Statistics as copied from the generated values on TravellerMap |
{Ix} | The Importance ranking of the world as generated from the T5: Core rules on pg. 411. |
WTN | The World Trade Number as generated from GT: Far Trader, but multiplied by 2. So a listed WTN of 5 becomes WTN of 2.5 when referencing the table on pg. 16 of GURPS Traveller: Far Trader. |
GWP (MCr) | The Gross World Product (in MCr) as generated pg. 14 of GT:Far Trader. |
Trade (MCr) | The volume of trade coming into and leaving the world (in MCr) per year. |
Passengers | Number of passengers entering and leaving the world per year, as generated by the rules on pg. 17 of GT: Far Trader |
RU | Resource Units as generated from the T5: Core rules on p. 435, and as updated according to errata. |
Build Cap | Shipyard capacity for constructing starships (in Tons) as generated from Trillion Credit Squadron. |
Army | The size of the standing army on the world measured in BEs, as generated from GURPS Traveller: Ground Forces |
Port / Shipyard | The size of the port on the world. A log scale value from 0 (the smallest) to 7 (the largest) as generated from GURPS Traveller: Starports pg. 59. |
SPA pop | Starport Authority employee population, as generated from GURPS Traveller: Starports pg. 65. |
