Data Overview 2018

This year has had ups and downs. Due to real-life distractions I haven't spent as much time on the site as I'd like. But reviewing the change logs, it has been a busy here. Here are some of the highlights....

Data Overview 2018
But first... offline

A highlight of the year was getting to meet and hang out with Marc Miller at TravellerCon/USA:

Joshua Bell and Marc Miller at TravellerCon/USA 2017

He's a big fan of maps, it turns out.

Who knew?


Mongoose had a successful Kickstarter for The Great Rift box set by Martin J. Dougherty, which emphasizes getting off the beaten track and exploring the mysteries of even deeper space. The set includes Corridor and Reft, the first look at Riftspan Reaches since a brief stop in Travellers' Digest, and the first ever official look at Afawahisa and Touchstone sectors. In addition, various calibration points and anomalies are marked on those sectors. Prep work was done for these on Traveller Map, including route generation borders, and reviewing previous canonical details.

Athwa subsector in Calidan from The Fall of Tinath adventure (also by MJD) in the Traveller Starter Set by Mongoose was added as well; this is part of the OTU, although resides far away from Charted Space. Watch out for the Essaray...

Graham Donald made an effort to ensure that many apocryphal versions of sectors were preserved. These are not part of the OTU, but used by many players regardless. They include: Fulani from Terra Traveller Times, Meshan from North Coast Roleplaying, Foreven from Imperium Staple, Morning Star (from Morgonstjärnen), Tagret from Judges Guild Pegasus IX, Vanguard Reaches and Beyond by Paranoia Press (1991 updates), Beyond by Jeff Zeitlin, and Precipice and Anniversary, including orphaned worlds and subsectors from various publications

Traveller 5 Sector Survey

We're making some progress on nailing down what the actual process is for reviewing sectors. The image shows the current status: red = complete, orange = in-review (and Foreven = green = preserve).  Not much change since last year, but Arzul and Star's End (by Jeff Zeitlin) were pulled in for review, as well as Touchstone and Afawahisa to support Mongoose's The Great Rift product.

T5SS Status 2018

For sectors already in review, Randy Dorman made corrections for the Solomani sectors in review (Canopus, Aldebaran, Neworld, Langere). Robert Eaglestone updated Tuglikki. Wayne H. Underkoffler made several updates to allegiances in Vanguard Reaches and the Beyond.

Other Efforts

In Zhodani space, Marc Miller has asked that we review unofficial and official data to understand the effects of the Wave, and certain historical events in Zhodani space.

BeRKA updated Zdiedeiant, Michael Gonzalez updated the coreward borders of the Consulate to match the old Imperium Map poster and library data, and I added newly generated data for Sidiadl and Eiaplial sectors, to round out the

Other Eras

M1900: Robert Eaglestone provided Tuglikki updates

M1120: Michael Gonzalez provided data for Core, Dagudashaag, Gushemege, Vland, Deneb, Riftspan Reaches, Corridor, Ealiyasiyw

Non-Data Updates

The bulk of my work on the site this past year was on getting the experience on mobile devices improved. The usual side effect when a web site does that is that the "desktop" experience is improved as well, and I hope that's the case. If you don't visit the site on a phone, here's what it looks like these days:

World Details (small)

Recent Site Outage

A few days ago I pushed an update to the site. Although everything tested fine locally, apparently one of the included changes introduced a serious bug impacting performance. I haven't tracked down the cause yet, but I've rolled back the code which seems to have helped:

The black line spiking up is CPU usage. Normally it's around 2 minutes per hour (i.e. the host machine is actually sitting idle most of the time). For the last few days it's been around 50 minutes per hour - meaning it's been spinning its wheels like mad. And when it's like that, every request is extremely slow - minutes instead of milliseconds.

Sorry about that. :(

It may take some time to track down, and the odds are high that I'll push a bad release or two out while trying to bisect down to the exact bug - and it takes a few minutes of monitoring to even notice that it's occurring. So please be patient.



Data Overview 2017

It's that time of year when look at the current state of the Traveller Map and the changes that happened over the last 12 months. (Past Overviews)

General Updates

Following the passing of Don McKinney just over a year ago a lot of the momentum for the Traveller 5 Second Survey project was lost, but contributors to the site kept iterating on and providing new data. Some of the updates include:

Milieu Support

To assist in the development of the new "Galaxiad" setting set in the far, far future of M1900 I added milieu support. Several developers jumped on the bandwagon to adapt published sectors or placeholders for borders from various eras in the history of Charted Space. The data in most of the milieu is pretty sparse as yet.

M1900 data by Rob Eaglestone

I added a few new visualizations, as well as experimental UI to control them.

You can see the Empress Wave bearing down on charted space circa M1105:

And turn on visualizing Jump-1 mains - here the Vilani Main:

Finally, towards the end of 2016 we rebooted the Traveller 5 Second Survey effort. Several additional sectors have been brought "In Review" and we've begun to do more cleanup of the data, looking for glitches that have crept it and making progress on the work Don started:

Now in review, joining the T5SS data set:

Happy New Year!



In Review: Cano, Alde, Newo, Lang, Tien, Gash and Tren

Similar post made over on Citizens of the Imperium.

After a long break, I can announce some progress on the T5SS effort.

Marc continues to have a high level mandate to create a stable, consistent data set for the OTU as a tool for authors. This allows him (and others) to e.g. understand the impact of the Wave on charted space from 1105 to 1900, or figure how how the Vilani formed the Ziru Sirka along J-1 mains thousands of years earlier.

The canonical data set resides in Marc's hands. I've spent time over the last few weeks reconciling it with changes made by DonM between October and December 2015 that never made it back to Marc, as well as a handful of corrections applied directly to the site. We now once again have a consistent basis for the T5SS, and I can resuming make updates to the site from it.

Over the last few days I tackled three big additions to the T5SS data set. These are all now considered "In Review":

Feedback should be directed to the COTI T5SS thread.



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.
