@turf/rhumb-destination

What is @turf/rhumb-destination?

@turf/rhumb-destination is a module from the Turf.js library that allows you to calculate the destination point given a starting point, distance, and bearing using rhumb lines. Rhumb lines are paths of constant bearing, which are useful for navigation and mapping applications.

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

Calculate Rhumb Line Destination

This feature allows you to calculate the destination point from a given starting point, distance, and bearing using rhumb lines. The code sample demonstrates how to use the `rhumbDestination` function to find a point 50 kilometers east of the starting point.

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

const start = turf.point([-75.343, 39.984]);
const distance = 50;
const bearing = 90;
const units = 'kilometers';

const destination = turf.rhumbDestination(start, distance, bearing, {units: units});
console.log(destination);

Other packages similar to @turf/rhumb-destination

geolib

Geolib is a library for geospatial calculations. It provides functions for distance calculations, finding the center of a collection of points, and more. Unlike @turf/rhumb-destination, Geolib does not specifically focus on rhumb lines but offers a broader range of geospatial utilities.

geodesy

Geodesy is a library for geodesic calculations. It includes functions for calculating distances, bearings, and destinations on the Earth's surface. While it provides more general geodesic calculations, it does not specifically focus on rhumb lines like @turf/rhumb-destination.

spherical-geometry-js

Spherical Geometry is a library for performing spherical geometry calculations, including distance and area calculations on the Earth's surface. It focuses on spherical rather than rhumb line calculations, making it different from @turf/rhumb-destination.

README

@turf/rhumb-destination

rhumbDestination

Returns the destination Point having travelled the given distance along a Rhumb line from the origin Point with the (constant) given bearing.

Parameters

• origin (Geometry | Feature<Point> | Array<number>) starting point
• distance number distance from the starting point
• bearing number constant bearing angle ranging from -180 to 180 degrees from north
• units [string] miles, kilometers, degrees, or radians (optional, default kilometers)

Examples

var point = {
  "type": "Feature",
  "properties": {
    "marker-color": "F00"
  },
  "geometry": {
    "type": "Point",
    "coordinates": [-75.343, 39.984]
  }
};
var distance = 50;
var bearing = 90;
var units = 'miles';

var destination = turf.rhumbDestination(point, distance, bearing, units);

//addToMap
destination.properties['marker-color'] = '#00F';
var addToMap = [point, destination]

Returns Feature<Point> Destination point.

🚀 New Modules

• @turf/line-offset Adds a new lineOffset module as per this issue. Basically takes an input line and returns a new line offset by the distance. (PR https://github.com/Turfjs/turf/pull/729 - Author @rowanwins)
• @turf/polygonize Polygonizes (Multi)LineString(s) into Polygons. Implementation of GEOSPolygonize function (geos::operation::polygonize::Polygonizer). (PR https://github.com/Turfjs/turf/pull/767 - Author @NickCis)
• @turf/transform-rotate Rotates any geojson Feature or Geometry of a specified angle, around its centroid or a given pivot point; all rotations follow the right-hand rule. (Issue https://github.com/Turfjs/turf/issues/747 - Author @stebogit)
• @turf/transform-translate Moves any geojson Feature or Geometry of a specified distance along a Rhumb Line on the provided direction angle. (Issue https://github.com/Turfjs/turf/issues/747 - Author @stebogit)
• @turf/transform-scale Scale a GeoJSON from a given point by a factor of scaling (ex: factor=2 would make the GeoJSON 200% larger). If a FeatureCollection is provided, the origin point will be calculated based on each individual Feature. (Issue https://github.com/Turfjs/turf/issues/747 - Author @stebogit)
