Milieu Support

Traveller uses the term milieu (plural: milieux) to describe a particular setting or era. Milieu include the Golden Age (described in Classic Traveller and Mongoose Traveller, circa 1105), the Rebellion (described in MegaTraveller, circa 1120), the New Era (circa 1202, 1248), Milieu 0 (from T4, from 0 through 300), Interstellar Wars (from GURPS Traveller: Interstellar Wars), and even alternate settings such as the GURPS Traveller alternate timeline (a.k.a. "Lorenverse").

The Traveller Map defaults to the Golden Age (circa 1105), which is the focus of the T5SS effort. It now offers experimental support for other Milieu. To enable it:

  1. Go to the Settings menu (gear)
  2. Check "Enable Experiments"
  3. A new Experiments menu (flask) will appear
  4. From that menu, select a milieu:

You can play with some other experimental features that are there.

The available milieux are currently:

  • The Interstellar Wars - featuring only the Solomani Rim as depicted in GURPS Traveller: Interstellar Wars by Drye, Wiseman and Zeigler. Data adapted by adapted by Dom Mooney
  • 990 - Solomani Rim War. Features the data from Gateway to Destiny (the Gateway Domain) which is all I have handy for that time period, from Gateway to PDF.
  • 1105 - this is the default, with data from T5SS and unofficial contributions
  • 1900 - the Galaxiad setting. This is a work in progress with just the Spinward Marches and parts of Gvurrdon, c/o Rob Eaglestone.
Submission of data to flesh out these milieux or start others are welcome!

The API docs are updated to include milieu parameters where supported. Note that the values currently supported are: IW, M990, M1900 - and leave the param off for the default. If data is not present for a sector in a given milieu you'll get 404 Not Found errors.

When generating images, placeholder markers (*) will be shown for systems where default (1105) data has a system.

There are some caveats with the experimental support:

  • Search does not consider milieux, so the results won't match what you see.
  • Routes do not consider milieux so those results will also be off, too
There are a few more bugs noted in the issue tracker. Additional bug reports welcome.



Data Overview 2016

Once a year we look at the current state of the Traveller Map and the changes that happened over the last 12 months.  (Past Overviews)

This year starts on a somber note, having lost some luminaries in the Traveller community, most notably Don McKinney who was heading up the Traveller 5 Second Survey project to produce an official dataset for the OTU. Don was responsible for sending me updates for the official data used on the map, and shepherding data through a review process. The process included dusting off fan-favorite sectors previously considered apocryphal, reviewing submissions by other Traveller writers and referees, and getting feedback after making the preliminary data available via the map. Don will be missed, and the T5SS process will definitely take a bit to get back on track.

Thanks primarily to Don's efforts, 2015 was a year of tremendous growth and refinement in the official dataset. And momentum was started that has continued since his death. I've delayed posting this because there is a lot of work coming down the pipeline, and it's tempting to wait for it to land. But let's get to the picture - or pictures this time, of what's in there now:

Data Overview
The usual round-up of changes in 2015:
It's useful to toggle the "Dim Unofficial Data" setting to see what's in the T5SS review pipeline:

I've also added a few overlay options to visualize stuff for the T5SS reviewers. Droyne/Chirper world locations:
Droyne Worlds ★ / Chirper Worlds ☆
Populations - the area of the circle is proportional to the population of the world, so you can only really see worlds with 10 billion or more sophonts. The large circle to Trailing is the (possibly apocryphal) Nooq Sphere, with a larger population than many entire sectors. This also shows where unofficial data may need some work:

And here's an overlay highlighting world Importance (a T5 stat derived from the UWP):

One last picture, that compares coverage versus the area from the original Imperium poster:

Charted Space
I'm sure there's more data to come soon, but I need to publish this before January runs out.

Happy 2016!



Data Overview 2016

... is coming soon.

SPOILERS: Despite the sad events of 2015, it's been a huge year for data and there's been a recent influx of data. I'm waiting for it to calm down a bit before posting.

Hang on, travellers...



Now on the Twitter


Because 140 characters is about my attention span these days. 


Another T5SS Data Drop: many new sectors In Review

The Vargr Extents and Julian Protectorate get some love in the latest T5SS data drop, with the following sectors newly "in review":
Also, way off on the Spinward edge of charted space, Group One's Theta Borealis – the last of the GDW "land grant" sectors – is now in review.

Some data corrections elsewhere as well. As always, check the sector data history on GitHub for the gruesome details, and provide feedback on the data on COTI.
