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. 1/86,400. The map was, for the time, a real innovation and a decisive technical advance. It is the first map to be based on a geodesic triangulation ...
One series of historic maps, published by Cassini, is a reprint of the Ordnance Survey first series from the mid-19th century but using the OS Landranger projection at 1:50,000 and given 1 km gridlines. This means that features from over 150 years ago fit almost exactly over their modern equivalents and modern grid references can be given to ...
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).
Railroad maps from the 19th century, like Rand McNally & Co.’s “Railroad Map of the United States,” can command modest prices on resale sites like eBay and Etsy (averaging from around $60 to ...
After the war, the Cassini Grid system was replaced with the Ordnance Survey National Grid (see § Transition to National Grid). However, the Cassini Grid system continued to be used to map colonial possessions into the 1960s. Hong Kong, for instance, was surveyed in 1962 for a series of 1:10,000 and 1:25,000 maps of the territory. These were ...
The Ordnance Survey Great Britain County Series maps were produced from the 1840s to the 1890s by the Ordnance Survey, with revisions published until the 1940s. The series mapped the counties of Great Britain at both a six inch and twenty-five inch scale with accompanying acreage and land use information.
In 1744, he began the construction of a great topographical map of France, [5] one of the landmarks in the history of cartography. Completed by his son Jean-Dominique, Cassini IV and published by the Académie des Sciences from 1744 to 1793, its 180 plates are known as the Cassini map .
