Dataset Direct Download Service (WFS): Artificialisation of agricultural and forestry natural areas (approach by land files)

Artificialisation can be defined as “the transformation of natural soil, agricultural or forestry, through management operations which may lead to partial or total waterproofing” (CEEREMA definition). This is a major challenge in Île-de-France where land pressure is high, including a significant need for housing construction and development of transport and rare natural, agricultural and forestry areas to be protected. The Land Files (FF) of the Directorate-General for Public Finance (DGFiP) describe in detail the land, the premises and the various property rights associated with them on 31 December of a year. FFs do not have data on artificialisation in their own right. Each year they measure the entire construction on a territory and whether or not there is a plot built. A specific treatment of the raw data is therefore carried out by CEREMA. By comparing the annual vintages, they allow a monitoring over time of the evolution of land tenure and thus indirectly the artificialisation of the soil. The limits of this treatment are explained by CEREMA on the website dedicated to this project.
