The Struve Geodetic Arc is a chain of survey triangulations stretching from Hammerfest in Norway to the Black Sea, through ten countries and over 2,820 km. Prior to the Struve Geodetic Arc, an arc of about 2,400 km had been measured in India by Lambton and Everest (completed in 1845), and a shorter arc in Lithuania by Carl Tenner. The new long arc, later to be known as the Struve Geodetic Arc, was eventually created by connecting earlier, shorter arcs to the southern one measured by Tenner, and their extension to the north and south. All components of the Struve Geodetic Arc are linked to one chain and a number of the Arc sites belong to national state geodetic reference networks that confer integrity even with the geodetic measurements processed today. Based on the resolutions of the Coordinating Committee, national representative organizations actively promote the Struve Geodetic Arc via different tasks, such as the producing post stamps and envelopes (completed by Belarus, Estonia, Finland, Latvia, Lithuania, Moldova, Sweden, Ukraine); making promotional movies and educational leaflets, books and articles; preparing exhibitions; translating documentation; restoring geodetic instruments and other materials, and even minting commemorative coins for the Struve Geodetic Arc (Belarus, Moldova).
