The French Geodesic Mission to the Equator (French: Expédition géodésique française en Équateur), also called the French Geodesic Mission to Peru and the Spanish-French Geodesic Mission, was an 18th-century expedition to what is now Ecuador carried out for the purpose of performing an arc measurement, measuring the length of a degree of latitude near the Equator, by which the Earth's ...
Charles Marie de La Condamine (French: [la kɔ̃damin]; 28 January 1701 – 4 February 1774) was a French explorer, geographer, and mathematician.He spent ten years in territory which is now Ecuador, measuring the length of a degree of latitude at the equator and preparing the first map of the Amazon region based on astro-geodetic observations.
The French Geodesic Mission to Lapland was one of the two geodesic missions carried out in 1736–1737 by the French Academy of Sciences for measuring the shape of the Earth. One expedition was sent to Ecuador to perform measurements near the Equator ; the other was sent to Meänmaa to perform measurements near the Arctic Circle .
The early work of the French Geodesic Mission, led by Charles Marie de La Condamine, was delayed and hindered by lack of cooperation from the local Spanish authorities. Indeed, in 1737 a personal dispute between Ulloa and the president of the Real Audiencia de Quito , Joseph de Araujo y Río, reached such a pitch that Araujo ordered the arrest ...
The placement of the equatorial line was defined throughout a 1736 expedition called the French Geodesic Mission.While such studies would later determine the exact measure and shape of the world, astronomers involved missed the possibility of encountering the remnants of highly sophisticated geographical achievements made on “Equatorial” territory for hundreds of years before their arrival.

The Toise of Peru had been constructed in 1735 for Bouguer and De La Condamine as their standard of reference in the French Geodesic Mission, conducted in actual Ecuador from 1735 to 1744 in collaboration with the Spanish officers Jorge Juan and Antonio de Ulloa.
