"Sur la description Géométrique de la France". Il n'est point douteux que toutes les erreurs que l'on remarque dans les Cartes, tant anciennes que modernes, ne viennent de ce que ceux qui les ont dressées, ont pris chacun des routes différentes les uns se sont contentez d'estimer les distances par le temps que l'on emploie à aller d'un lieu à l'autre les autres ont mesuré actuellement la longueur des chemins: ceux enfin qui ont opéré avec plus d'exactitude, ont formé quelques triangles dont ils ont observé les angles avec des planchettes ou d'autres instrumens encore plus imparfaits. ^ "Des villages Cassini aux communes d'aujourd'hui".Vivier had, "come by order of the King" and was, "employed by order of the King to work on the Map of the Kingdom under the direction of the Academy of Sciences." Gallery Picard and La Hire write in 1672 that King Louis XIV instructed the Academy of Sciences to, "create a map of all of France with the greatest precision possible.", Cassini writes that in September 1672, M. Cassini noted such methods were bedridden with instrumental errors and were susceptible to parallax. Ĭassini, alongside other scientists like Picard and Roëmer and Richer, investigated movement of the planets relative to Earth. This would result in confounded errors when compiling these maps into one. Sometimes, triangulation was used though often relying on the magnetic pin of a compass without concern for one's latitude. At the time distances between settlements, to be portrayed on maps, were often estimated by the time of the journey between them or by measuring the length of the road. The genesis of the Cassini Map came during the reign of Louis XIV, with the creation of the Academy of Sciences alongside the ambitions of Jean-Baptiste Colbert for France's navy, the defence of her coasts and fixing the imprecision of the country's maps. It is of particular interest to archaeologists, architects, historians, geographers, genealogists, treasure hunters and ecologists who need to retrospect ecology or understand the history of landscape. Nowadays, researchers frequently consult the Cassini map sheets, in its paper form in the reading room of the maps and plans department of the Bibliothèque nationale de France, or its digital form online. The work of the Cassinis even left its mark on the land where today you can still find toponyms such as " Signal of Cassini." Such landmarks correspond to the corners of the triangles that formed the backbone of Cassini's map. The map does not precisely locate dwellings or the boundaries of swamps and forests, but the level of precision of the road network represented is such that by superimposing satellite photos onto map sheets of France, spectacular results are obtained. Four generations of the Cassini carried out the work, taking more than 6 decades to complete. It is the first map to be based on a geodesic triangulation. The map was, for the time, a real innovation and a decisive technical advance. It was on a scale of one line to 100 toises, i.e. It was compiled by the Cassini family, mainly César-François Cassini (Cassini III) and his son Jean-Dominique Cassini (Cassini IV) in the 1700s. The Cassini Map or Academy's Map is the first topographic and geometric map made of the Kingdom of France as a whole. ![]() ![]() ( Learn how and when to remove this template message) For more guidance, see Wikipedia:Translation.You should also add the template to the talk page.A model attribution edit summary is Content in this edit is translated from the existing French Wikipedia article at ] see its history for attribution.
