Versailles on the Cassini map. The Cassini Map or Academy's Map is the first topographic and geometric map made of the Kingdom of France as a whole. It was compiled by the Cassini family, mainly César-François Cassini (Cassini III) and his son Jean-Dominique Cassini (Cassini IV) in the 1700s. It was on a scale of one line to 100 toises, i.e ...
The Cassini projection (also sometimes known as the Cassini–Soldner projection or Soldner projection [1]) is a map projection first described in an approximate form by César-François Cassini de Thury in 1745. Its precise formulas were found through later analysis by Johann Georg von Soldner around 1810. [2]
Map of the French coast, corrected by the Academy of Sciences in 1682. In the year 1634, France ruled by Louis XIII and Cardinal Richelieu, decided that the Ferro Meridian through the westernmost of the Canary Islands should be used as the reference on maps, since El Hierro (Ferro) was the most western position of the Ptolemy's world map.

Hand-drawn map of one side of the Valley of Vesdre by French geographers (led by the Cassini family) from 1745 to 1748. In France, the first general maps of the territory using a measuring apparatus were made by the Cassini family during the 18th century on a scale of 1:86,400 (one centimeter on the chart corresponds to approximately 864 meters on the ground).
Cassini has run low on propellant, and will become an artificial meteor at Saturn on Friday morning as it plunges to its death. NASA is now receiving the last photos ever taken by the Cassini ...
Giovanni Domenico Cassini was also the first of his family to begin work on the project of creating a topographic map of France. In addition, Cassini also created the first scientific map of the moon. [6] The Cassini space probe, launched in 1997, was named after him and became the fourth to visit Saturn and the first to orbit it.
One of its most important goals was the derivation of an international ellipsoid and a gravity formula which should be optimal not only for Europe but also for the whole world. The Mitteleuropäische Gradmessung was an early predecessor of the International Association of Geodesy (IAG) one of the constituent sections of the International Union ...
