    QWhere are you getting the flight data?
  • ge96 1 day ago
    Why is there almost no traffic in places like South America (other than Brazil) and Africa? Data set or reality? Not much in China/Russia either.
    • coolwulf 1 day ago
      The current data is from OpenSky, mainly north america and EU.

    Zooming on a mouse wheel on windows is nearly unusable, it goes from whole of europe to town level in one mouse wheel notch.

      im on a mac and had the same issue.

      other bugs: when i pan around (while zoomed far in), the planes arent in a fixed position on the map, they shift with the pan

      ux bug: when i zoom in, it zooms into the middle of the browser window instead of where my cursor is.

        I just modified zooming algo a lit, now it should improve your user experience.
      • coolwulf 1 day ago
        I will take a look to fix these bugs.
      • coolwulf 1 day ago
        also fixed the parallelex problem of route trail vs. the plane icon

      I am on Mac. Will try to get on a Windows box to test this

    There's something a little off about the projection logic when you drop into the Leaflet view, you'll notice that when you pan around after zooming the planes shift their location.

    Very cool demo though!

    • coolwulf 1 day ago
      Need to check my calculations. Thanks for noticing it.
    • coolwulf 1 day ago
      This is fixed now.

    Updated to version 1.3, now on mobile phone (iOS/Android), it should have better user experience.

    Impressive. The planes should probably scale up a bit as you zoom though, they become impossible to spot.

    I'm surprised all the flights in the world can be represented in a <500KB api call

    • coolwulf 1 day ago
      try change to satellite view it will be more visible
  • ddoolin 1 day ago
    When you zoom in to the street map level, the planes are practically invisible with their color and thin borders. Pretty neat though, that's a lot to load and keep smooth.
    • coolwulf 1 day ago
      If you switch to satelite view, the planes will be very visible.
  • coolwulf 1 day ago
    For people having problems navigating, you can search flifht number on the left search bar. When click on the flight number, the view will jump over.

    Makes the divide between the developed and developing world very clear.

    Edit: can’t be right. I think this is a dataset problem. China and Brazil should have more dots.

    • coolwulf 1 day ago
      opensky database is limited. I need to find some data source for China and south America
  • paulnsorensen 1 day ago
    Wow. I won't give you a feature request :) just appreciation.

    It really puts into perspective the magnitude of air traffic when you have this visualization.

  • ab_testing 1 day ago
    How are you getting that real time flight data from . Is there a free source for this ?
    • coolwulf 12 hours ago
      you can check OpenSky, they have API with free tier.
  • c0nsumer 1 day ago
    When zooming in and it switches to the lighter color tiles, the icons basically become invisible.
    • coolwulf 1 day ago
      the airline flight number attached to the icon is in dark color and should be visible, also could switch to satelite view when zoom in, which is dark color
  • concensure 1 day ago
    Did you pay for flight api? Getting comprehensive real time flight data is quite a monetary challenge
    • coolwulf 1 day ago
      I registered on OpenSky and using their API
  • lwansbrough 1 day ago
    Could probably extrapolate positions based on heading and speed, to do some fake "real time" positions.
  • Glubker 1 day ago
    Really cool! Curious to know how you made it render everything so fast with barely any loading.

    Good work.

    • coolwulf 1 day ago
      :P just optimize to the extreme
  • pstomi 1 day ago
    It render extremely fast on my side (firefox, macOS). Which UI stack are you using? Is it egui?
    • coolwulf 1 day ago
      It's mainly eGui + WebGPU

    wow, more than 10K airbuses just over the NA. Looks like airplanes are the major source of air pollution.
  • moci 1 day ago
    It seems there is very little flight data from China.
    • coolwulf 16 hours ago
      That's the limitation of current OpenSky api. Most of Chinese airlines data are not in it.
  • Levitating 1 day ago
    The wasm file (flight_viz_bg.wasm) was 10.94 MB as reported by firefox.
    • coolwulf 1 day ago
      I changed a higher resolution image and that is why now it is a little bigger...
      • Levitating 20 hours ago
        If it's just the image, you could try using more aggressive compression?
  • amelius 1 day ago
    Can you add pinch zoom?
    • coolwulf 1 day ago
      Currently I developed this for desktop browser, so it might not work well on mobile. But I will improve and update it.
      • pohl 1 day ago
        You should be able to do pinch zoom support for laptops with a trackpad, too. I think it would be

        window.addEventListener('wheel', ... )

        Fantastic work!

      • amelius 1 day ago
        Ok, I'm on desktop now. And I notice another "issue". When I use my mouse wheel to zoom, the point that my mouse cursor is on is not stationary. This makes it hard to zoom in on e.g. a specific aircraft or landmark.
        • coolwulf 1 day ago
          I can take a look. The current zoom is zooming to screen center. Maybe I should change it to cursor location.
          • amelius 19 hours ago
            Yes, that will definitely be an improvement.
