GeodesyLib

This library contains the most used geodetic calculations both in spherical and rhumb way.

Usage

Import

1. Go to release page.
2. Download the lates release of the package.
3. Import it to your unity project.

Code Documentation

A doxygen output for the documentation of the code is included and will be included at every release. So, head to the releases page and find the document in the downloads section of the related version.

Examples

From Coordinate

Coordinate  _from = new Coordinate(52.205, 0.119); 

To Coordinate

Coordinate _to = new Coordinate(48.857, 2.351);

Haversine Distance

double result = _from.HaversineDistance(_to);

Bearing

double result = _from.CalculateBearing(_to);

Spherical Law Of Cosines

double result = _from.CalculateSphericalLawOfCosines(_to);

Calculate Mid Point

Coordinate result = _from.CalculateMidPoint(_to);

Calculate Intermediate Point

double fraction = 0.88; // Fraction should be between zero and 1 (0-1)

Coordinate result = _from.CalculateIntermediatePointByFraction(_to,fraction);

Calculate Destination Point

Coordinate result = _from.CalculateDestinationPoint(distance, bearing);

Get N Coordinates Between Two Coordinates

Coordinate[] result = _from.GetNCoordinatesBetweenTwoCoordinates(_to, 50);

Calculate Equirectangular Approximation

double result = _from.CalculateEquirectangularApproximation(_to);

Calculate Intersection Point

Coordinate firstCoordinate = new Coordinate(51.8853, 0.2545); // somewhere in UK
           double firstBearing = 108.55d;

           Coordinate secondCoordinate = new Coordinate(49.0034, 2.5735); // somewhere in France
           double secondBearing = 32.44d;

           //act

           Coordinate result = SphericalCalculations.CalculateIntersectionPoint(
               firstCoordinate, firstBearing,
               secondCoordinate, secondBearing);
