DVF+ open-data

Since May 2019, data “Request of Flow Values” (DVF) is available in open-data. The **DGALN** and **Cerema** propose “DVF+ open-data”, which allows free access to the same data in the form of a geolocated database easily exploitable for the observation of land and real estate markets**. The structuring of the proposed DVF data is based on the **shared data model called “DVF+”**, resulting from the work carried out at the initiative of the **national DVF group** and which has been in existence since 2013. This model, developed to facilitate analysis, provides a table of mutations in which each line corresponds to the information and location of a transaction. Geolocation is based on the various vintages of the computerised cadastral Plan also available in open-data. Each of the variables in the DVF+ model is calculated solely from the raw data of DVF. The calculated variables apply throughout the territory and are subject to a shared methodology. There is no exogenous data at this stage except geolocation data from the PCI Vector. Note that the DVF+ model is also the basis for the creation of the database [DV3F](https://datafoncier.cerema.fr/donnees/donnee-dv3f).
