{wiki=General_levelling_of_France}
The General Levelling of France, known as "Nivellement Général de la France," is a comprehensive geodetic survey that was completed in the 19th century. Its main purpose was to precisely determine the elevation of various points across France in relation to a fixed reference point, primarily to understand the topography of the country better and to aid in engineering and construction projects. The project began in 1792 and continued under various administrations until the mid-19th century.
