ISensorXform Interface

Provides access to members that control sensor specific geodata transform.

Members

	Name	Description
	ConstantZ	The constant Z value in meters.
	CorrectGeoid	Indicates if Geoid correction is needed.
	DEM	The Digital Elevation Model (DEM).
	RequireDEM	Indicates if DEM is required for applying this transform.
	ZFactor	The conversion factor from DEM Z unit to meters.
	ZOffset	The Z offset in meters applied to DEM.

The constant Z value in meters.

Public Property ConstantZ As Double

public double ConstantZ {get; set;}

This property can be used to set a constant elevation across the image when DEM method is not used.

Indicates if Geoid correction is needed.

Public Property CorrectGeoid As Boolean

public bool CorrectGeoid {get; set;}

If the property is set to true, the DEM used in orthorectification will be corrected to use the true elevation.

The Digital Elevation Model (DEM).

Public Property DEM As IRaster

public IRaster DEM {get; set;}

Indicates if DEM is required for applying this transform.

Public Property RequireDEM As Boolean

public bool RequireDEM {get; set;}

The conversion factor from DEM Z unit to meters.

Public Property ZFactor As Double

public double ZFactor {get; set;}

A factor that converts the unit of the DEM to meter

The Z offset in meters applied to DEM.

Public Property ZOffset As Double

public double ZOffset {get; set;}

If the DEM data used is not based on sea level, this property can be used to do the adjustment.

Classes	Description
ApproximationXform	A transformation that approximates other transformations.
CompositeXform	A composite geodata transform collection class.
EpipolarXform	A transformation that map native image to epipolar image.
Formosat2Xform	A Formosat2 transform class.
FrameXform	A standard frame camera model transformation class.
PushbroomXform	A Pushbroom sensor model class.
RPCXform	A Rational Polynomial Coefficient (RPC) transform class.
SARXform	A SAR transform class.
SICDXform	Sensor Independent Complex Data (SICD) Xform.
SPOT5Xform	A SPOT5 1A transform class.

The ISensorXform interface is used to set the elevation information for RPCXform object to create orthorectified image.

You can specify the elevation using a DEM or a constant value that represent an average elevation.
