 Elevation is needed for any ossim sensor models that do earth intersects at height above the 
-ellipsoid.  This is derived from two parts, the geoid grid (vertical datum), and the height above mean sea level which usually comes from elevation cells, sometimes referred to as a digital elevation model(DEM).  Elevation cells are relative to a given vertical datum.  At runtime the ossimElevManager will supply sensor models with the height above ellipsoid which is "geoid_grid_point + elevation_cell_post".  This happens automatically provided you have set up you ossim_preferences file correctly and have the appropriate data in you elevation repositories.
