class CoordinateSystemTransform in Tinman.Terrain.Georef

A CoordinateSystemTransform object is used to transform coordinates from one CoordinateSystem (geographic or projected) into another one.

sealed class

CoordinateSystemTransform

implements

ICoordinateFlip

Remarks

The CoordinateSystemTransform class wraps zero, one or two ICoordinateTransform s (for projected source and/or target coordinate system) and zero or one IDatumTransform s (for different GeodeticDatum s).

Public / Attributes

IsFlip

Does this coordinate system transform flip the handedness?

public property	IsFlip { get }
type	bool
value		true if the coordinate system handedness if flipped, false if not.
implements	ICoordinateFlip.IsFlip

IsIdentity

Checks if this coordinate system transform is the identity transform.

public property	IsIdentity { get }
type	bool
value		true if this is the identity transform, false if not.

Remarks:

This property only refers to the numerical identity of the transformation, i.e. output coordinates will be equal to input coordinates.

Source

The source coordinate system.

public property	Source { get }
type	CoordinateSystem
value	[not-null]	The source coordinate system.

Target

The target coordinate system.

public property	Target { get }
type	CoordinateSystem
value	[not-null]	The target coordinate system.

Public / Constructors

CoordinateSystemTransform

Creates a new instance of CoordinateSystemTransform.

public constructor	CoordinateSystemTransform (CoordinateSystem source, CoordinateSystem target, IDatumTransform datumTransform = null)
params	source	[not-null]	The source coordinate system.
	target	[not-null]	The target coordinate system.
	datumTransform		Optional datum transform. If null, a lookup will be performed into the current GeoRegistry. Defaults to null.
