Cassini's map

The 181 plates of the map of Cassini are gathered on 2 CD-Rom dividing France into two parts (northen and southern) using a virtual line from La Rochelle to Geneva.

The plates located on this limit line can be found on both CD-Rom. The data for the maps have been gathered between 1760 and 1789 and are drawn to the scale 1/86400.

They have been digitalised in black and white with a high resolution (400dpi - which means for the scale, a pixel for 5.5m); so the least of the details of the map can be seen.

Indeed these details are many : the Cassini men have recorded the different kinds of roads, villages, abbeys, farms, wayside crosses, mills, battle fields, pitfalls, waterways, ponds, marshlands, woodlands, ... Refering to the map key is enough to be convinced.
