The Struve Geodetic Arc, another WHS, marked a major step forward for earth sciences and topographic mapping.
The arc helped establish the exact size and shape of the earth.
The arc represents points of a survey carried out between 1816 and 1855 by the astronomer Friedrich Georg Wilhem Struve, stretching from Hammerfest in Norway to the Black Sea, through 10 countries and more than 2,820km.
