Classics in Geodesy from the 18th & 19th Centuries
From the measurement of meridional arcs by the French in the early part of the 18th Century it became evident that the Earth was not a perfect sphere but an oblate spheroid instead. It took about 150 years to get accurate values for the equatorial and polar radii of an ellipsoid to represent the figure of the Earth. Here are some of the classic works on the development of modern geodesy.
1720 Cassini, De la Grandeur de la Terre
1738 Maupertuis, La Figure de la Terre (in English)
1740 Picard, Degre du Meridien
1743 Clairaut, Theorie de la Figure de la Terre
1749 Bouguer, La Figure de la Terre
1805 Biot, Traite elementaire d'astronomie physique (in English)
1826 Airy, Figure of the Earth
1830 Everest, Measurement of an Arc of the Meridian
1830 Airy, Figure of the Earth
1841 Bessel, Ueber einen Fehler und der Figur der Erde
1847 Everest, The Meridional Arc of India, Vol. 1, Vol. 2
1858 Clarke, Principal Triangulation, GB Ordinance Survey
1866 Clarke, Figure of the Earth
The 18th Century French units of length may be helpful with the earlier works.
