The Struve Arc is a chain of survey triangulations stretching from Hammerfest in Norway to the Black Sea, through 10 countries and over 2,820 km. These are points of a survey, carried out between 1816 and 1855 by the astronomer Friedrich Georg Wilhelm Struve, which represented the first accurate measuring of a long segment of a meridian. This helped to establish the exact size and shape of the planet and marked an important step in the development of earth sciences and topographic mapping. It is an extraordinary example of scientific collaboration among scientists from different countries, and of collaboration between monarchs for a scientific cause.Also,it is an extraordinary interchange of human values in the form of international scientific collaboration, as well as an outstanding example of a technological ensemble.
10 countries where chain of survey was conducted-
Belarus, Estonia,Finland,Latvia,Lithuania,Norway, Republic of Moldova,
Russian Federation, Sweden, Ukraine.
