Metro in Kazan Full-wave and binary forms.

Foundation area of the constructed station of the metro. Foundation area is strengthened on the perimeter by pile wall with the steel revetment. Volume around the pile wall is strengthened injection of concrete (marks 9m, 20m and 28m along horizontal). On the colored frame much more fine details is distinguished which are not visible on the binary frame. Due to the amplitude discrimination full-wave form gives higher spatial resolution in comparison with the binary form.
