Mercatori universaalne põiksilindriline projektsioon. Referentsellipsoid: WGS84 6°-te tsoonidega, kus Eesti paikneb kahe tsooni ulatuses: tsoon 34V, mille telgmeridiaan Lo = 21° 00'; tsoon 35V, mille telgmeridiaan Lo = 27° 00'. Mõõtkavategur: k = 0,9996.
For the design of topographic maps, other countries, especially the United States, currently use the Gauss-Krüger projection with 6° meridian zones in a form called the Universal Transverse Mercator (UTM) projection, which was adopted by the US Army Map Service in 1947 for their use in worldwide mapping.
