The
Struve Geodesic
Arc is a chain of topographic
triangulations that extends from the vicinity of Hammerfest, in northern
Norway, to the Black Sea through ten countries and more than 2,820 km (1,752
mi). It was used to make the first precise measurement of a meridian. The chain
was established and used by the German-Baltic scientist Friedrich Georg Wilhelm
von Struve between the years 1816 to 1855 to establish the exact size and shape
of the earth. The first point of the Arch is at the Tartu Observatory in
Estonia, where Struve did much of the research on it. The triangulation chain
measurement comprises 258 principal triangles and 265 geodetic vertices. In
2005, the chain was inscribed on the World Heritage List as a memorable
ensemble made up of 34 commemorative plaques or obelisks built from the 265
points of the main station.
Friedrich
Georg Wilhelm von Struve, born on April 15, 1793 and died on November 23, 1864,
studied at the University of Dorpat (present-day Tartu, in Estonia, then in the
Russian Empire) and did his research as an astronomer at the observatory of
that city, of which he was director. In 1831 he published Beschreibung der
Breitengradmessung in den Ostseeprovinzen Russlands ('Description of
latitude measurement of the Baltic provinces of Russia').
