Haversine

Implements the Haversine formula to calculate the distance between two points on a sphere.

The formula allows to compute the haversine of θ (that is, hav(θ)) from the latitude (represented by φ) and longitude (represented by λ) of the two points:

Where:

• φ1, φ2 are the latitude of point 1 and latitude of point 2,
• λ1, λ2 are the longitude of point 1 and longitude of point 2.

Installation

Add the dependency if you are using Maven:

<dependency>
    <groupId>dev.loqo71la</groupId>
    <artifactId>haversine</artifactId>
    <version>1.0</version>
</dependency>

Or if you are using Gradle:

implementation group: 'dev.loqo71la', name: 'haversine', version: '1.0'

Usage

To get the distance between two points, you can use the static method calculateDistance(Coordinate source, Coordinate target).

Haversine.calculateDistance(40.6892, 74.0445);

By default Kilometers is the unit of measure, but you can also use Meters and Miles.

Haversine.calculateDistance(40.6892, 74.0445, Unit.Kilometers);
Haversine.calculateDistance(40.6892, 74.0445, Unit.Meters);
Haversine.calculateDistance(40.6892, 74.0445, Unit.Miles);
