ILSRXform Interface

Provides access to members that control a Local Space Rectangular transform.

Members

	Name	Description
	Domains	The domains in output space.
	EquatorialRadius	The earth Equatorial radius.
	Flattening	The earth flattening.
	IsIdentity	Indicates if this geodata transform is an identity transform.
	PerspectiveCenter	The sensor position.
	RotationMatrix	The 3x3 rotation matrix.
	SpatialReference	The output spatial reference after applying this transform.
	Transform	Transforms a set of points in a given direction.
	TransformCellsize	Transforms a cellsize in a given direction.
	TransformExtent	Transforms an extent in a given direction.
	TransformPoints	Transforms a point collection in a given direction

ILSRXform.EquatorialRadius Property

The earth Equatorial radius.

Public Property EquatorialRadius As Double

public double EquatorialRadius {get; set;}

Remarks

See put_Flattening for more information.

ILSRXform.Flattening Property

The earth flattening.

Public Property Flattening As Double

public double Flattening {get; set;}

Remarks

Each ellipsoid model is defined by the equatorial radius in meters and a flattening factor, typically around 0.003 (or 1/298). The exact values for many ellipsoid models are published. Sometimes the flattening is expressed as the inverse value (298.1234), but in this case the actual flattening value is required.

ILSRXform.PerspectiveCenter Property

The sensor position.

Public Property PerspectiveCenter As IPoint

public IPoint PerspectiveCenter {get; set;}

ILSRXform.RotationMatrix Property

The 3x3 rotation matrix.

Public Property RotationMatrix As Object

public object RotationMatrix {get; set;}

Description

Used to rotate the image based on the sensor orientation. See IFrameXform::putPerspectiveMatrix for additional information.

Inherited Interfaces

Interfaces	Description
IGeodataXform	Provides access to members that control geodata transformation.

Classes that implement ILSRXform

Classes	Description
LSRXform	A Local Space Rectangular transform class.

Remarks

In some aerial surveys a local reference plane coordinate system is used for each frame, rather than an establishes spatial reference system for the entire aerial survey. In these cases the LSR (local space rectangular) coordinate system is defined by the perspective center, rotation matrix and ellipsoid model.
