CoClasses that implement ISensorXform

CoClasses and Classes Description
ApproximationXform A transformation that approximates other transformations.
CompositeXform A composite geodata transform collection class.
CSMXform CSM transformation class.
Formosat2Xform A Formosat2 transform class.
FrameXform A standard frame camera model transformation class.
RPCXform A Rational Polynomial Coefficient (RPC) transform class.
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.
