IGeoTransformation Interface

Provides access to members that define a geographic (datum) transformation.

Description

Most methods and properties are inherited from ITransformation. Each geographic (datum) transformation also has a name, a 'from', and a 'to' spatial reference.

Members

	Name	Description
	GetSpatialReferences	Returns the from and to spatial references for the transformation.
	Name	The name of the geographic transformation.
	PutSpatialReferences	Sets the from and to spatial references for the transformation.
	TransformMeasuresFF	Transforms floating point measures to floating point measures (or do the inverse).
	TransformMeasuresFI	Transforms floating point measures to integer measures (or do the inverse).
	TransformMeasuresIF	Transforms integer measures to floating point measures (or do the inverse).
	TransformMeasuresII	Transforms integer measures to integer measures (or do the inverse).
	TransformPointsFF	Transforms floating point points to floating point points (or do the inverse).
	TransformPointsFI	Transforms floating point points to integer points (or do the inverse).
	TransformPointsIF	Transforms integer points to floating point points (or do the inverse).
	TransformPointsII	Transforms integer points to integer points (or do the inverse).

IGeoTransformation.GetSpatialReferences Method

Returns the from and to spatial references for the transformation.

Public Sub GetSpatialReferences ( _
    ByRef from As ISpatialReference, _
    ByRef to As ISpatialReference _
)

public void GetSpatialReferences (
    ref ISpatialReference from,
    ref ISpatialReference to
);

Description

Each geographic transformation is defined by 'from' and 'to' geographic coordinate systems.

IGeoTransformation.Name Property

The name of the geographic transformation.

Public Property Name As String

public string Name {get; set;}

IGeoTransformation.PutSpatialReferences Method

Sets the from and to spatial references for the transformation.

Public Sub PutSpatialReferences ( _
    ByVal from As ISpatialReference, _
    ByVal to As ISpatialReference _
)

public void PutSpatialReferences (
    ISpatialReference from,
    ISpatialReference to
);

Inherited Interfaces

Interfaces	Description
ITransformation	Provides access to members that apply a function (or its inverse) to a set of points or measures. The suffix of each method indicates the type of parameters operated on.
