Details

The BD Forêt is a database where the forest cover of France is stored by department, with the spatial distribution of tree species in the country.

The BD Forêt version 1 was developed by photointerpretation of infrared color aerial images with a minimum mapped area of 2.25 hectares. The year of reference for each department varies between 1987 and 2002. The version 1 contains the following variables:

• ID: surface object identifier

• CODE_TFV: alphanumeric code of the vegetation formation

• TFV: vegetation formation type

• TFV_G11: type of coverage and predominant composition of the vegetation in 11 groups

• ESSENCE: description of tree species according to the unique basic nomenclature for all departments

The BD Forêt version 2 was developed between 2007 and 2018 by photointerpretation of color infrared images from the BD ORTHO. It assigns a vegetation formation type to each mapped area larger than 5,000m^2. This version contains the variables:

• DEP: department name

• CYCLE: order number of the departmental revision

• ANREF: year of reference of the data

• TFIFN: code of the departalmental type of vegetation cover. The nomenclature is specific to each department

• LIBELLE: departamental type of vegetation cover. The nomenclature is specific to each department

• LIBELLE2: departamental type of vegetation cover in capital letters. The nomenclature is specific to each department

• TYPN: code of the national type of vegetation cover

• NOMB_TYPN: national type of vegetation cover

For more information, download the metadata using the argument path_metadata (information in French).
