       Show HN: Skies-adsb 2.0 - my 3D plane-tracking web app
        
       Hello, I'd like to share a 3D plane tracking web app that I
       developed called: skies-adsb.  Living near KMIA (a very busy
       airport), I spend a lot of time plane spotting and thought it would
       be cool to track planes in 3D.  In October 2021, I built a
       prototype 3D ADS-B flight tracker called skies-adsb using p5.js.
       In April 2022, I released version 1.0 of skies-adsb, rewritten in
       Three.js. However, this release still relied on manual editing of
       GeoJSON layers.  By late 2024, I had learned enough about GIS and
       GeoPandas to automate map creation using custom GeoJSON layers.
       During the Christmas holiday, I developed a script to generate
       these layers from Natural Earth, FAA, and OpenStreetMap data using
       GeoPandas, then refactored skies-adsb to render multiple GeoJSON
       layers.  Today, version 2.0 of skies-adsb is available! This
       release simplifies installation, automates GeoJSON map creation,
       and features a new rendering engine. skies-adsb is compatible with
       all major WebGL-enabled mobile and desktop browsers.  To run skies-
       adsb you will need an RTL-SDR receiver and a Linux workstation or
       Raspberry Pi, or you can connect to an existing RTL-SDR ADS-B
       installation.  Working on this app has brought me a lot of joy and
       I also learned a lot about aviation, weather, GIS, and Three.js
       along the way. I use it daily, typically leaving it running in the
       background like a digital aquarium. I hope you enjoy it too.

         | Hi. I'm not planning a native app at this time. I created an
         | experimental native app using Godot, but in the end I decided
         | to focus on the web app. The app is a PWA so it provides a
         | native like experience if that is desired (works on both mobile
         | and desktop)--this is how I use it when I'm on my phone or
         | tablet. Most users likely already have an ADS-B tracker that
         | usually includes a local lighttpd web server for 2D traffic
         | viewing. The app integrates with these existing setups. Users
         | who don't want to alter their setup can run the app using the
         | included Vite development server and websocket proxy to connect
         | to a ADS-B tracker. Instructions are in `docs/LOCALHOST-SETUP-
         | GUIDE.md`.

             | start doing that? The company that bought them don't seem
             | to be mainly a jet charter a company, but describe
             | themselves as a "Aviation Market Data" company.

         | adsbexchange was also bought out by private equity recently,
         | these two seem to be some of the larger fully community driven
         | resources.

         | 
         | One of the best is https://airplanes.live/ - which currently
         | aggregates data from nearly 1700 feeders globally; they have a
         | legal agreement preventing sale of this data (to avoid

         | 
         | One of the largest ones, Opensky Network - is supposed to be

       | Congrats, this looks nice
       | 
       | Does this app render the flights to fit the curvature of the
       | earth?
       | 
       | Was looking for something like this during the New Jersey drone
       | flap to help identify distant flights from the perspective of
       | someone on the ground

         | The app currently renders aircraft and maps on a flat plane
         | using latitude, longitude, and altitude, via the
         | sphericalmercator library:
         | 
         | https://github.com/mapbox/sphericalmercator
         | 
         | My understanding is that the ADS-B latitude and longitude are
         | based on the WGS 84 coordinate system, which accounts for the
         | Earth's curvature, but the app itself doesn't project these
         | coordinates onto a curved surface.
         | 
         | I'd appreciate suggestions from HN users with map projection
         | expertise on how to accomplish this. I'm also interested in
         | learning more.
         | 
         | One of my next projects is to get a better understanding of GIS
         | coordinate reference systems in order to be able to create 3d
         | globle renderings of the data. I purchased the following two
         | books to better understand map projection implementation:

         | Ring
