@turf/rhumb-bearing

What is @turf/rhumb-bearing?

@turf/rhumb-bearing is a module from the Turf.js library that calculates the bearing between two geographical points along a rhumb line (a line of constant bearing). This is useful for navigation and mapping applications where you need to determine the direction from one point to another.

What are @turf/rhumb-bearing's main functionalities?

Calculate Rhumb Bearing

This feature calculates the rhumb bearing between two geographical points. The code sample demonstrates how to use the `rhumbBearing` function to find the bearing from point1 to point2.

const turf = require('@turf/turf');

const point1 = turf.point([0, 0]);
const point2 = turf.point([10, 10]);
const bearing = turf.rhumbBearing(point1, point2);
console.log(bearing);

geolib

Geolib is a library for geospatial calculations. It provides a variety of functions for distance, bearing, and other geographical calculations. Unlike @turf/rhumb-bearing, Geolib offers a broader range of geospatial utilities but may not be as specialized in rhumb line calculations.

geodesy

Geodesy is a library for geodesic and rhumb line calculations. It offers detailed and precise methods for calculating distances, bearings, and other geospatial metrics. Compared to @turf/rhumb-bearing, Geodesy provides more comprehensive geodesic calculations but may be more complex to use.

@turf/rhumb-bearing

rhumbBearing

Takes two points and finds the bearing angle between them along a Rhumb line i.e. the angle measured in degrees start the north line (0 degrees)

Parameters

• start Coord starting Point

• end Coord ending Point

• options Object? Optional parameters (optional, default {})

  • options.final boolean calculates the final bearing if true (optional, default false)

Examples

var point1 = turf.point([-75.343, 39.984], {"marker-color": "#F00"});
var point2 = turf.point([-75.534, 39.123], {"marker-color": "#00F"});

var bearing = turf.rhumbBearing(point1, point2);

//addToMap
var addToMap = [point1, point2];
point1.properties.bearing = bearing;
point2.properties.bearing = bearing;

Returns number bearing from north in decimal degrees, between -180 and 180 degrees (positive clockwise)
