i.ortho.elev  is  used  to select or modify the target elevation model for orthorectification of imagery.
       This elevation model is essential for both the computation of  photo-to-target  parameters  and  for  the
       actual  orthorectification  of imagery group files.  The elevation model selected should cover the entire
       area of the image group to be orthorectified.  Optionally, scaled elevation data can be converted to real
       elevation values specifying a mathematical expression.
