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.

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.
