struct LatLng

(Niantic.Lightship.AR.VpsCoverage.LatLng)

Overview​

The LatLng struct represents a Latitude and Longitude pair and provides functionality for comparing LatLng instances with each other.

	struct LatLng: IEquatable< LatLng > {
		// fields
	
		 double Latitude => lat_degrees;
		 double Longitude => lng_degrees;

		// methods
	
		LatLng(double latitude, double longtitude);
		LatLng(LocationInfo locationInfo);
		bool Equals(LatLng other);
		override int GetHashCode();
		override string ToString();
		override bool Equals(object obj);
		double Distance(LatLng other);
		LatLng Add(double bearing, double distance);
		LatLng ToRadian();
		LatLng ToDegrees();
		static double Distance(LatLng l1, LatLng l2);
		static double Bearing(LatLng l1, LatLng l2);
		static bool operator == (LatLng l1, LatLng l2);
		static bool operator != (LatLng l1, LatLng l2);
	};

Methods​

Distance​

double Distance(LatLng other)

Calculates "as-the-crow-flies" distance between points using the Haversine formula.

    Returns:

    Distance between points in meters.

Add​

LatLng Add(double bearing, double distance)

    Parameters:

    bearing - Bearing in degrees, clockwise from north

    distance - Distance travelled in meters

Distance​

static double Distance(LatLng l1, LatLng l2)

Calculates "as-the-crow-flies" distance between points using the Haversine formula.

    Returns:

    Distance between points in meters.

Bearing​

static double Bearing(LatLng l1, LatLng l2)

Calculates the initial bearing (sometimes referred to as forward azimuth) which if followed in a straight line along a great-circle arc will take you from the l1 to l2 points.

    Returns:

    Initial bearing in degrees
