An odd Shaped Stamp Released By Finland showing the Survey Triangulation Done Using Struve Arcs
Wonder how people came to know the shape of earth is round ?Do you know how the first accurate measuring of a long segment of a meridian was done ?
The Struve Arc [Featured On Stamps Of Finland] are a series of survey triangulations,spread over from Hammerfest in Norway to the Black Sea,passing through 10 countries and spread over 2820 km. Struve Arcs are points of a survey, carried out between 1816 and 1855, by the well known Russian astronomer Friedrich Georg Wilhelm Struve.
The original Struve arc consisted of 258 main triangles with 265 main station points. The survey helped in deciding the shape of
earth and helped in the development of accurate topographic mapping. It consists of 34 of the original station points, with different marking - from a drilled hole in rock, through iron cross, cairns, or built obelisks.
