The CoordinateReferenceSystem type exposes the following members.

Constructors

	Name	Description
	CoordinateReferenceSystem	Initializes a new instance of the CoordinateReferenceSystem class

Properties

	Name	Description
	Projection	Gets the projection used by the CRS.
	Transformation	Gets the transformation used by the CRS.

Methods

	Name	Description
	Distance	Returns the distance between two geographical coordinates.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetType	Gets the Type of the current instance. (Inherited from Object)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
	Scale	Returns the scale used when transforming projected coordinates into pixel coordinates for a particular zoom. For example, it returns 256 * 2^zoom for Mercator-based CRS.
	ToString	Returns a string that represents the current object. (Inherited from Object)
	Translate(GeoCoordinate, Double)	Translates the given geographical coordinate to a cartesian point at the given zoom level.
	Translate(Point, Double)	Translates the given cartesian point to a geographical coordinate at the given zoom level.
	Zoom	Returns the zoom level corresponding to the given scale factor.

Extension Methods

	Name	Description
	GetEnumValueOrDefault	Gets the enumeration constant for value, if defined in the enumeration, or a default value. (Defined by EnumExtensions)
	GetEnumValueOrDefaultT	Gets the enumeration constant for this value, if defined in the enumeration, or a default value. (Defined by EnumExtensions)
