geolib

What is geolib?

The geolib npm package provides a set of functions for common geospatial calculations. It allows you to perform operations such as distance calculations, finding the center of a set of coordinates, and working with bounding boxes.

What are geolib's main functionalities?

Distance Calculation

This feature allows you to calculate the distance between two geographic coordinates. The `getDistance` function returns the distance in meters.

const geolib = require('geolib');
const distance = geolib.getDistance(
  { latitude: 51.5103, longitude: 7.49347 },
  { latitude: 51.515, longitude: 7.453619 }
);
console.log(distance); // Outputs distance in meters

Finding the Center of Coordinates

This feature allows you to find the geographic center of a set of coordinates. The `getCenter` function returns the center coordinate.

const geolib = require('geolib');
const center = geolib.getCenter([
  { latitude: 51.5103, longitude: 7.49347 },
  { latitude: 51.515, longitude: 7.453619 },
  { latitude: 51.525, longitude: 7.470 }
]);
console.log(center); // Outputs the center coordinate

Bounding Box Calculation

This feature allows you to calculate the bounding box for a set of coordinates. The `getBounds` function returns the bounding box.

const geolib = require('geolib');
const bounds = geolib.getBounds([
  { latitude: 51.5103, longitude: 7.49347 },
  { latitude: 51.515, longitude: 7.453619 },
  { latitude: 51.525, longitude: 7.470 }
]);
console.log(bounds); // Outputs the bounding box

geodesy

Geodesy is a library for geodesic calculations. It provides functions for distance calculations, bearing, and other geospatial operations. It is similar to geolib but focuses more on geodesic calculations.

geokit

Geokit is a library for geospatial calculations and queries. It provides functions for distance calculations, bounding boxes, and other geospatial operations. It is similar to geolib but includes additional features for working with geospatial data in databases.
