public class TLcdPolynomialRasterReferencer extends Object implements ILcdRasterReferencer
The referencer returns an ILcdRasterReference
whose model
reference is an ILcdGridReference
. The projection of this
ILcdGridReference
is a
TLcdRectifiedPolynomialProjection
.
If the initial reference of the model tie points is also an
ILcdGridReference
, then the newly created grid reference will
have exactly the same parameters, except that the initial projection is
wrapped inside the rectified projection. Thus, you can consider the new
reference system as being equivalent to the original reference, but slightly
adjusted to match the tie points.
If the initial reference of the model tie points is an
ILcdGeoReference
, then the newly created grid reference will
be a ILcdGridReference
with the same geodetic datum.

An optional array can be provided for obtaining the model tie points transformed to image coordinates on return. These reflect the effects of the referencing. The differences between the transformed model tie points (expressed in pixels) and the original image tie points (also expressed in pixels) provide a measure for the success of the referencing. With a perfect raster reference, the resulting model tie points correspond to the original image tie points.

aImageWidth
- the image width of the raster, expressed
in pixels.aImageHeight
- the image height of the raster, expressed
in pixels.aImageTiePoints
- the image tie points, expressed in pixels.aModelReference
- the reference of the model tie points.aModelTiePoints
- the model tie points corresponding to the
image tie points, expressed in model
coordinates.aMappedModelTiePointsSFCT
- an optional array for obtaining the
the model tie points mapped to image
coordinates upon return. This parameter
may be null
, if the mapped
points are not required.
