Traveller Map: API Data Interpretation

[myrmidon009]

All,

This is my first post on the Traveller forums. I've been playing it for the past year or so, both with my kids and my local gaming group, and have come to love it! It's good to be here.

I have a question about the Traveller map (travellermap.com). I'm not sure where else to post it, so I thought I'd bring this up here.

I would like some help interpreting system data extracted using the API. I used the SEC Data API to extract the data for all systems in a sector. I understand most of it, but there are a few entries that I don't know. Below is a list of those entries. I have browsed the API documentation, but haven't found the answers.

• Remarks
  • This covers Trade Codes, but also lists other things. What are the other labels listed under here?
• {Ix}
• (Ex)
• [Cx]
• N
• B
• PBG
• W
• Stellar
• Does any of this indicate whether or not a gas giant is present?

Could anyone define what those labels mean, and give me guidance on how to interpret them? Thank you all very much.

This should all be available at https://travellermap.com/doc/secondsurvey

Some of what you are looking for might be in different versions of Traveller that may not be used in Mongoose or show up in multiple locations depending on the label. Example EX can be Exile Camp in Trade codes or Economic Extension value.

That's just what I needed. Thank you very much!

A follow-on question:

Using the API, is there a way to locate a sector in relation to other sectors, or in Charted Space generally? For example, to locate the Spinward Marches to the right of Foreven and to the left of Deneb.

Dunno about API, but if you suck down the git repository you can get that info from travellermap/res/Sectors/M1105/M1105.xml . Of course, you have to be able to parse the XML to do that programmatically, which IME is no fun.

That's what the Universe API is for:

API - Traveller Map

travellermap.com

Querying that gives you a list of sectors and coordinates for the given milieu.

Great! Thank you very much.

Also, given the coordinates in a sector, you can query by coordinates to get adjacent sectors. But slurping down the whole sector list via the universe API isn't that much data and avoids multiple queries.

In general, avoid taking dependencies on any of the source files or server files beyond the API, as those are subject to change. The client side of the site (map itself, makers, etc) relies almost exclusively on the API, except for a few things like a static JSON file of mains, world images, etc.

If you click on an empty hex, the TravellerMap pulls up information about the whole sector -- including where the Sector is in relation to Core (the numbers immediately after the sector name; for the Trojan Reach it is -4, 0). The first value is left & right (negative values are to the left / Spinward), and the second value is up and down (negative values are down / Rimward).
