Announce flights of anything directly overhead.

Overhead

A simple demo web app designed to tell you what flights are directly overhead.

Setup

Copy private_keys_template.py to private_keys.py and fill in with your own details.

To run

FLASK_ENV=app flask run

Will run the app on localhost:5000.

What it does

Displays local planes in the air and (if unmuted) plays a sound whenever a plane is directly overhead, so you can quickly identify it.

How it does it

This flask/JS app queries the OpenSky REST API for local flight information using location information returned by IPStack. If the user gives permission, the page instead uses HTML5 geolocation for much more accurate location info. It generates a map using leaflet.js and MapBox.

This is only meant to be run locally, for your own amusement. You must update private_keys.py with your own API keys for these services to work.

JS opensky api call

Hi, I love the project, Thanks for helping me out bc I'm doing something similar :)
I found how to do the opensky api call from the browser, just leaving it in case anyone is interested

export async function getFlights( coords ) {
 
     // get the user's longitude and latitude
     const [ longitude, latitude ] = [ coords.longitude, coords.latitude ];
 
     // find the min and max longitude and latitude of the search area
     const kmPerDegreeLatitude  = 111.2
     const kmPerDegreeLongitude = 111.2 * Math.cos( latitude / 180 * Math.PI )
     const latitudeDegrees  = SEARCH_DISTANCE / kmPerDegreeLatitude
     const longitudeDegrees = SEARCH_DISTANCE / kmPerDegreeLongitude
 
     // build the query string
     const parameters = {
         lamin: latitude  - latitudeDegrees,
         lomin: longitude - longitudeDegrees,
         lamax: latitude  + latitudeDegrees,
         lomax: longitude + longitudeDegrees
     }
     const queryString = new URLSearchParams(parameters).toString();
 
     // make the request and set the openskyResponse variable
     const response = await fetch( OPENSKY_URL + "?" + queryString, {method: "GET", headers: HEADERS} );
     const openskyResponse = await response.json();

    return openskyResponse;
}
