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.
