Syntax

public struct LongLat : IEquatable<LongLat>

Public Structure LongLat
	Implements IEquatable(Of LongLat)

The LongLat type exposes the following members.

Constructors

	Name	Description
	LongLat	Constructs a LongLat object with the specified longitude and latitude (take care not to mix these up).

Properties

	Name	Description
	Latitude	Gets the latitude: a number between -90 and 90 (both inclusive) representing the South/North coordinate. -90 represents the South Pole, 90 represents the North Pole, and 0 represents the equator.
	Longitude	Gets the longitude: a number between -180 and 180 (both inclusive) representing the West/East coordinate, zeroed on a line passing to the rear of the Royal Observatory, Greenwich (near London in the UK).

Methods

	Name	Description
	DistanceTo	Returns a Distance that represents the shortest distance along the surface of the Earth from this to the specified longLat.
	East	Returns a LongLat that represents a position the specified distance East of this.
	Equals(LongLat)	Returns true if other has the same Longitude and Latitude values as this.
	Equals(Object)	Returns true if obj is a LongLat instance with the same Longitude and Latitude values as this. (Overrides ValueTypeEquals(Object))
	GetHashCode	Overridden to ensure consistency with Equals. (Overrides ValueTypeGetHashCode)
	North	Returns a LongLat that represents a position the specified distance North of this.
	South	Returns a LongLat that represents a position the specified distance South of this.
	ToString	Returns a non-null, non-empty string representation of this instance for logging and debugging purposes. (Overrides ValueTypeToString)
	West	Returns a LongLat that represents a position the specified distance West of this.

Operators

	Name	Description
	Equality(LongLat, LongLat)	Determines whether two specified LongLat instances are equal.
	Inequality(LongLat, LongLat)	Determines whether two specified LongLat instances are not equal.

Remarks

Also provides useful methods for measuring distances between points and moving points North, South, East, and West.

Thread Safety

Instances of this struct are immutable and safe for use from multiple threads at once.
