More Geodesy Classics from the 17th - 19th Centuries

  Picard's improvement of surveying methods in the 17th Century led to an effort to measure the length of the degree in order to determine the size of the Earth. Here are some more geodesy classics with some of the earlier work.

1671 Picard, Mesure de la Terre

1680 Picard, Voyage D'Uranibourg

1684 Picard, Traite du nivellement

1738 Celsius, De observationibus pro figura telluris

1740 Picard, Degre du Meridien entre Paris et Amiens

1742 Maupertuis, Elements de Geographie

1750 Cesar-Francois Cassini, La meridienne de l'Observatoire royal de Paris

1751 Condamine, Mesure des trois premiers degres du Meridien...

1751 Condamine, Journal du voyage fait par ordre du Roy a l'equateur

1860 Struve, Arc du Meridien, Vol. 1, Vol. 2

The arc of the meridian in Lapland that was first measured by Maupertuis and Celsius was extend from the Arctic Ocean to the Black Sea and is now know as the Struve Geodetic Arc. Some of the station points and markers of this arc still exist and have been recommended as World Heritage sites.
