Zhodani mapping scheme?

[ShawnDriscoll]

I haven't loaded any Zhodani sectors yet. You can see a blue world or two in the corner so far. I was curious if anyone else thought it was weird how the Zhodani use the same mapping scheme as the Imperium? I know they call the Spinward Marches sector by another name. But that is the only difference I've seen so far with them.

Your maps are provided by the Travellers Aid Society (Faithfully serving travellers since the Year 0) so of course they are mostly in Galanglic and follow Imperial mapping conventions. I’m sure Zhodani traders will happily import some Zho-style maps for you.

The Zhodani use a mapping system fundamentally incompatiable with Imperial thinking. Maps are available, but incomprehensible to the Imperial mind. The greater enlightment of the Zhodani allowed for what would be a TL 28 technology in Imperial space: the concept of space in 3 dimensions.

The best minds of the Imperium spent decades researching this, but when they suggested that the Zhodani might actually be correct and that space might indeed consist of three dimensions, they were stripped of their status and beaten by angry TAS cartographers.

The whole debacle is still treated as an Imperial secret, but the echo of the event can still be felt whenever a Traveller mentions that forbidden third dimension.

I was looking for worlds with Red Zones. Found some in a Zhodani sector. Interesting. I didn't find any in the Spinward Marches. I thought for sure it would have a bunch of Red Zone worlds. Maybe it was the Referee's doing.

I found 19 spinward marches red zone worlds:

Spin B Grant ImDd X664100-3 R
Spin C Pscias ImDd X555423-2 R
Spin C Shionthy ImDd C000742-8 R

Spin F Asgard ImDd X5437C7-5 R

Spin G Ylaven ImDd X587552-4 R
Spin H 457-973 ImDd X572776-5 R
Spin I Torment DaCf X433268-6 R
Spin K Gorram ImDd X554220-2 R
Spin M Andor ImDd C695735-9 R

Spin H Huderu ImDd X575000-0 R
Spin I 494-908 DaCf X893000-0 R
Spin N Nirton NaXX X500000-0 R

Edit: 613 red zone worlds in Traveller Map for Milieu M1105 (Official || Unreviewed || InReview) && OTU.

The sector with the code "Vang" has the most, at 58, Cano has 51. Spinward marches is 7th highest, actually.

What filter are you using to find them?

 

[ShawnDriscoll]

I see. I think the computer is looking only if other things are found as well about a world. Will have to look.

ADDED:
Ok. It seems the computer is only looking for Travel Zones after it learns the Allegiance of a world. I don't have all of those pegged yet.

MORE ADDED:
My bad. She says she's only looking at high-pop worlds (in her mind) for zones. High-pop being 'A' or higher.

I told her to turn off that filter. Fixed.

Thanks for your helps. I been working on this app without actually looking at the data files, or knowing which ones I've downloaded so far. More challenging.

"she"? Do travellers anthropromorphize software?

At any rate, there are 21 TravellerMap worlds with population A or greater and red zones:

Will check that too.

ADDED:
I don't have the complete set. So not as many as you have. Need to buy more gum.

I'm not sure you're aware, but you don't have to import the sector data by hand. Travellermap has a pretty good api and several different methods to grab the data.

I just grabbed all of the sector data with https://travellermap.com/data, grabbed the "Sectors" from that, filtered that for M1105 and (Official, InReview, Preserve) and OTU, then just iterated through that list with the published API, first getting the sector coordinates with https://travellermap.com/data/SECTOR/coordinates then pulling down the actual T5 data in TSV with https://travellermap.com/data/SECTOR/tab, then processing that.

I had to do a little in the way of gymnastics to compute world positions from that but that's not strictly necessary, but pretty easy too. The whole thing - pulling down all of the data from travellermap, doing the appropriate local database queries to get what you want, build the associations and parse the data takes about 25 seconds all in, and I'm using a really naive approach.

There might be some reason that I'm not aware of that you're doing it by hand, but you will probably save some frustration later on by putting together the code to do it automatically. Also, I presume the map data on travellermap is updated periodically, having an automated system to collect the data and import it will save having to do this all again.

 

[ShawnDriscoll]

I know zip about API right now. And I don't want to superping the map server by accident. So I just copy/paste RAW sector data as I need it. The data I do have is for testing anyway. My app will be used for my own game sector data when it is finished. Just want to make sure that it works with OTU data before I start making my own sectors for it.
