Development of Geodetic Projections for Syrian Region

Abstract

This paper presents a methodology for development of a unified and comprehensive model for calculating geodetic projections, adapted to Syrian region. Thes      e projections are based on common conformal (cylindrical, azimuthal and conical) geodetic projections Theory. This aims to improve accuracy in calculating coordinates, to cope up with the available accuracy in measurments. Direct and indirect convergence and scale factor formules were written in this context.

A case study was carried out to present methods of finding best fitting projections for the Syrian region. The presented methodology allows controlling of values of linear distortions by changing scale factors in origin point. We can also control distribution of distortions inside the studied region by changing the position of the origin point. This research yieldes some results and recommandations for spatial data management in the studied region.
