The measurement of 32 triangles in the hard inter-Andean alley since 1736 and 1740, in conclusion the arc of the meridian was 3 ° 7'11 ".

The contribution of the Condamine Mission to the knowledge of the shape and dimensions of the Earth was remarkable, however, the advances of science determined that in the middle of the 19th century, will rethink the problem of precision that had served as the foundation of Geodesy.

The International Geodesic Association, founded in 1862, had been planning the need to re- measure the arches of Lapland and of Ecuador, it was France that once again committed to commissioning the work to the Geographical Institute of the Navy.

In 1899 an exploration was carried out and it was decided to measure a larger arch than the one of the Mission of the Condamine. This mission took place in the 20th century, from 1902 to 1906 they measured an arc of 5 ° 53'34 ", between Tulcán to the North and the peruvian Port of Paita to the South. It was commanded by Georges Perrier and Paúl Rivet.
