Ellipsoid Correction

Ellipsoid Correction RD Operator

The operator implements the Range Doppler orthorectification method [1]. The implementation is exactly the same as for the Range Doppler Terrain Correction operator except that the averaged scene height is used instead of DEM.

Parameters Used

The following parameters are used by the operator:

1. Source Band: All bands (real or virtual) of the source product. User can select one or more bands. For complex product, i and q bands must be selected together. If no bands are selected, then by default all bands are selected.
2. Image resampling method: Interpolation methods for obtaining pixel values from source image. 
3. Map Projection: The map projection types. The orthorectified image will be presented with the user selected map projection.
