Projection of topographic elements from the topographic surface on the reference surface is a very important operation necessary because the field observations are reported at the geoid vertical by the position of the plumb line, while the calculus are performed on ellipsoid after the instrumental observation were projected on the reference ellipsoid after the normal direction to the ellipsoid. For the correction calculus of reduction on ellipsoid of geodetic observation is necessary the preliminary determination of the ,,N” geoid undulation and the deviation components of vertical line. There are several methods in which we can bring geodetic points of the topographic surface to the reference surface. Some of the methods are: the design method, the development method, the Pizzetti method, the Bruns-Helmert method.
