Spinward Flow

First preliminary step in revision: Imgur Link (3602 × 5209 png image) (recommend opening in new tab)
This version of the Spinward Marches began with the M1105 map saved on Travellermap (sector data and metadata) that I have copy/pasted into offline files for hand editing. I am using the Poster webpage to run iterations (lots and lots and lots of iterations!) of my edits to check for errors and learn how the database records and parses information.
The current changes that I have been making are exclusively to the Metadata file ... which controls the locations of borders, polity labels and Express Network routing. Updating the sector data to modify UWPs and Trade Codes will happen in a later step (because it's more detail intensive and boring to cross-check
).
Since LBB S3 (printed 1979) contains no border delineation markings on any of the maps (just notations on UWP entries), my references for where the borders "ought to have been" rely on use of maps by Fifth Frontier War partial coreward 1/3 of the sector (printed 1981) and the CT Alien Module: Darrians, page zero map (printed in 1987). There are some pretty obvious disagreements (and let's be honest with ourselves, obvious errors!) between these sources with regards to some specific details, so I've done my best to interpolate between the different CT sources provided to at least try and get the mapping of the borders right. Where borders "disagree" between Travellermap's version and LBB S3 allegiances I have given priority and precedence to LBB S3 (hence why Wardn and Olympia in Lunion subsector are independent, claimed by neither the Sword Worlds nor the Imperium). Also, the specific date used for this map follows LBB S3 with regards to ownership of the Entropic Worlds (later seized by the Sword Worlds during the Fifth Fontier War, post-1105).
The biggest and most obvious revisions to the Express Networks (plural!) happen in the Sword Worlds (Mjolnir and Gungnir return to the Sword Worlds network as shown in LBB S3) and in the almost wholesale reworking of the Lunion subsector ... with minor ripple effects on the Sword Worlds, Lanth and Mora subsector Express Network nodes.
Rather than routing through Caladbolg <J4> Biter <J3> Adabicci <J3> Lunion as we're all accustomed to seeing, I've shifted the Express network routing between Lunion and the Five Sisters to run through Caladbolg <J4> Wardn <J1> Tenalphi <J3> Shirene <J1> Lunion.
Additionally, I've decided that the Lunion/Adabicci/Ianic "misprint" is basically an "off by one" error. If you move this XBoat route coreward, you instead connect Lunion/Rabwhar/D'Ganzio, which is MUCH more sensible.
Another change to the Express Network that I've made is in Mora subsector. Instead of going from Fornice/Carey/Capon I have shifted the route slightly coreward to instead be Fornice/Mercury/Capon. This shift improves routing of XBoats between Mora and either Lanth (within 4 jumps from Mercury) or Rhylanor (within 3 jumps from Mercury) ... whereas before the routing would have involved 5 jumps from Carey to Lanth or 4 jumps from Carey to Rhylanor (so the change speeds things up by 1 jump with no loss of J2 distribution by Scout/Courier to nearby systems). I consider this adjustment to be yet another "off by one" error in the original LBB S3 that just got perpetuated.
The last change to the Express Network that I implemented was returning the link between Chamois/Trin's Veil/Spinward Marches and what I can only assume must have been Tuwayk/Gulf/Deneb as depicted in LBB S3.
As advertised previously, but just to be clear ... I haven't gotten around to reverting UWPs yet to LBB S3 (with the occasional required changes, such as Kinorb/Regina, for example, to be compliant with LBB3.77 which was the reference point when LBB S3 was published) with this project but that will take more time than this (simple?
) update to the sector's metadata file.
Once I've got all the changes I'm making dialed in a proofed for LBB3.77 "legality" of results for UWPs, I'll be able to save attachment files to this post containing all the edited data the prompts Travellermap to produce the results that I'm achieving.
For reference, I'm needing to do all of my spreadsheet work in Plain Text format (so .txt file saves to prevent data format corruption) using the TextEdit Version 1.18 (394) app for OSX on my iMac2 computer ... just in case anyone else would like to try their hand at doing anything similar themselves.
Next step ... proofing and correcting the sector map UWPs and Trade Codes to be LBB S3 compliant (and where necessary, corrected).
