Experimental justification of implementation of the composite projection in Azerbaijan

: Transnational communication lines differ from other objects of the economy both in form and size, and in the task of their geodetic support, which requires the development of special methods for its solution. One of the ways of geodetic support with high accuracy is the choice of optimal (with minimal distortion) geodetic projection for the territories of transnational communication lines. Composite projection is one of the most appropriate methods to choose the optimal projection. This article presents the argumentation and results of experimental calculations for the implementation of optimal geodetic projection for transnational communication lines in Azerbaijan.
