Graphical adjustment of resections

Abstract

One of the most convenient methods for inserting a new point into an existing network in terms of field work is the resection method (Pothenot, Snelius problem). At sea near the coast and when traveling with a panorama of mountains, back resection to already known points and peaks is almost the only way to quickly and accurately determine the location. Also, resections obtained photographically, both during ground and aerial photography, are reduced to the Potenot problem on a plane. Therefore, any simplification of the solution to this problem deserves attention.
