The proposed method makes it possible to obtain photos during normal mapping and with a horizontal position of the optical axis of the camera by closing the contacts of an electrical circuit using a gyro-vertical at the moment of zero value for the bank angle. This provides the possibility of developing the photos in portable devices under expedition conditions. In order to hasten the execution of readings the increased coordinate for the following calculation of height and wave lengths and increasing of the accuracy of these calculations in the proposed device, a needle indicator is mounted on the longitudinal carriage. In addition, in order to directly obtain profiles of waves with respect to the vertical planes parallel to the photography base a pantograph is rigidly mounted with the longitudinal carriage and is displaced from the transverse carriage.
