Accessing Airspace Restriction Data using OpenSky Network API

OpenSky Network provides an API for accessing airspace data, including information about restricted areas, temporary flight restrictions, and other airspace-related data. This guide demonstrates how to use the OpenSky Network API in JavaScript (Node.js), C#, and Python to fetch airspace restriction data.

Info

You need to sign up for a free account on OpenSky Network's website to get your API credentials (username and password).

Code Examples

Here are code examples for accessing the OpenSky Network API in JavaScript, C#, and Python. Be sure to replace your_username and your_password with your OpenSky Network API credentials.

Install axios library

Install the axios library by running the following command:

JSC#Python

mkdir opentsky-test
cd opensky=test
npm install axios

npm install axios

npm install axios

Code

JSC#Python

const axios = require('axios');

// Replace these with your OpenSky Network API credentials
const username = 'your_username';
const password = 'your_password';

const getRestrictedAirspaceData = async (latitude, longitude, radius) => {
try {
    const url = `https://opensky-network.org/api/states/all?lamin=${latitude - radius}&lomin=${longitude - radius}&lamax=${latitude + radius}&lomax=${longitude + radius}`;

    const response = await axios.get(url, {
    auth: {
        username: username,
        password: password,
    },
    });

    // Filter the data to get only restricted airspace information
    const restrictedAirspaceData = response.data.states.filter((state) => {
    // Implement your logic to filter restricted airspace data
    // based on the data received from OpenSky Network API
    // For example: return state[16] === 'RESTRICTED';
    });

    return restrictedAirspaceData;
} catch (error) {
    console.error('Error fetching airspace data:', error);
    return null;
}
};

// Example usage
const latitude = 37.7749;
const longitude = -122.4194;
const radius = 0.1; // In degrees

getRestrictedAirspaceData(latitude, longitude, radius).then((data) => {
console.log('Restricted airspace data:', data);
});
