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, which yielded the first accurate measurement of a meridian.he new flattening estimate was one part in 298.257 222 101 and the equatorial radius was 6,378,136.8 metres. An earlier survey, in 1740, had given flattening at one part in 178 and an equatorial radius of 6,396,800 metres.
