Study of processing for 1:200 000 scale topographic maps of Mongolia

Article Resolution #25 of the Government of Mongolia dated as of January 28, 2009, provides that the international geodesy coordinates of WGS-84 shall be used for geodesy measurement and processing, the Baltic Sea structure shall be used for height network and the UTM reflex of the world horizontal merkater shall be used for large and medium scale topographic mapping respectively based on Articles 5.2.1 of the Geodesy and Mapping Law of Mongolia. There is a research rationale to adjust distortion generated from transferring procedure from TM projection of CS-42 (coordinate system 1942) reference system into UTM projection of WGS-84, an Earth-fixed terrestrial reference system.
