Thread: Maps and visualizations

    JEEZ! Awesome visualisations

    I have my server set to automatically pull and sync the data from EDSM, and update the map. Unfortunately, EDSM doesn't have any incremental bulk dumps of the body data, just the giant weekly dump that's currently over 10 GB in size. So I have my map configured to do this once every two weeks. I'll have to test it, of course, but this should automatically keep the map mostly up to date here: http://elite.necrobones.com/

    Thanks!

    This is great work! Thanks for sharing!

    I've added a 20 ly resolution map that is just the overhead and side views. I can't quite run this at 10 ly resolution without running out of memory on the server, plus it actually doesn't look as good. So 20 isn't bad for now.

    Oh hey, that's even better. Thanks! Wish I could rep you again.
    And I have to admit, on these maps, most everything I've done in the past year (or maybe two) show up as clumps, without any lines leading to them.

    These are really excellent maps. Love it.

    The galactic neutron fields show up remarkably clear in that latest rendering

    Yeah, I'm a little torn on whether to include visited systems without scanned stars, and how to represent it, since the focus here was more on colorizing the star classes. Either way, it's a pretty cool visualization, I think.

    The top and bottom of the core look awfully flat in the side on views.

    Are you truncating those at some arbitrary height or is it really that smooth (if you can call +/-10ly variations "smooth")?

  10. #25
    They're actually that "smooth". I'm calculating to +/- 6000 ly, but the stars end around +/- 3000 or so in most places. The map would actually show stars all the way up to the distance rulers (and an equal distance on the "bottom") if there were any there.

  11. #26
    Mhm, and bear in mind that this visualization shows reachable systems, as it thankfully doesn't include trilaterated EDSM system data. There might be a few generated systems higher than that, but the average distance between systems must be higher than 140 ly. The drop-off at +/- 3000 ly is that sharp then anyway, but I wonder: is that the top of the lower sector, or the very bottom of the higher one?

  12. #27
    Yeah, since it's EDSM scanned stars only, it doesn't say anything about what else is actually out there. That's a good question about the sectors. Do the sector names transition at zero on the galactic plane? They're 1280 ly in size, so three stacked up from the plane would reach to +/- 3840.

    Looking at the data for the "top" of the galaxy, not taking into account scanned stars, my EDSM data has 43 systems above +3000 ly:

    I looked at a few sectors from the list in my post above, and they seem to have system data starting around +2535, or around there.

    Also I looked close to the core, and it appears the sector name transition happens around -25 on the "Y" coordinate.

    Code:
    mysql> select edsm_id,id64,name,coord_x,coord_y,coord_z from systems where coord_x>=-10 and coord_x<=10 and coord_y>=-50 and coord_y<=50 and coord_z>=25990 and coord_z<=26010 order by coord_y;

    Yep, the plane is at -25 LY if you assume that the plane corresponds to the sector boundary.

    There does appear to be a hard limit for the proc gen galaxy according to mass code type. These are from EDSM (adjusted for cube boundaries):

    At the top:
    H +3815
    G +3175
    F +2855
    E +2855
    D +2775
    C +2775
    B +2775
    A only one system recorded

    At the bottom:
    H -3,865
    G -3,225
    F -2,905
    E -2,905
    D -2,905
    C -2,865
    B -2,845
    A only one system recorded

    The limits for H, G, F and E codes match my own manual searching and whilst it can't be guaranteed that there aren't higher or lower values it does seem like something that can be relied upon. I'm less confident about D, C and B codes since these aren't symmetric about the plane (the bottom ones go down further than the top ones go up).

  15. #30
    Huh, interesting to see the mass codes fall off gradually like that.

    For the maps I'm generating, I moved the center based on the position of Sgr-A*, but re-centered by several hundred lightyears to visually center the galaxy a little bit better. Here's the coordinate center I've been using: 25, -20, 25000.

    I could shift it to use -25 on the Y, to correspond to the galactic plane, but we're talking about a fraction of a pixel at that point.
