Abstract
A method for surveying is disclosed which functions to define all curves, grades and super elevations to a parabolic shape by impinging two laser beams, each of which is provided with a grid type means so as to create a diffracted fan of beams emitted from each laser. The intersections of these beams are utilized to form the parabolic shapes.
