The creation of the Melotte cadastre began in 1721 and ended in 1727. This makes it one of the oldest cadastres in Europe and in the world. Although Lausanne had already been the subject of a schematic cadastre in the 17th century, the Melotte is the first geometric survey of the city. The Melotte cadastre embodies the Lausanne of the Enlightenment, and the surroundings. Because of its age, it is of particular historical importance for the history of urban planning and cartography. The Melotte sheets have already been extracted and geolocalized and they could be the subject of further extraction in the near future.
