Where each figure comes from
- Area
- Computed on the sphere from longitude and latitude (turf.area), not in Lambert-93. For an appellation this is the union of the INAO polygons across commune boundaries, measured on the unclosed geometry; the fifteen metres used to close the outline for the map are not counted. For a climat it is the union of the cadastral lieu-dit polygons with that name.
- Planted
- Parcel area times vineyard cover, where cover comes from the IGN vegetation layer supplemented by the agricultural declaration. Checked against the customs harvest declarations: median deviation 5.1 per cent over a hundred appellations.
- Elevation
- Mean of the elevation-model cells whose centre falls inside the polygon, on a 5 m grid.
- Name of the named plot
- The letters come from the land registry, which records lieux-dits in capitals and without accents. Capitalisation and accents are restored with a per-commune dictionary built from the INAO denominations, the BD TOPO toponyms and a manual list (name-overrides.json). Cru names come straight from the INAO and skip this step. Restoring the accents is our own step and not the source: 2,576 names show "Lès" where the registry writes "LES". Where the dictionary does not know a word, the registry form stands.
- Organic
- Share of the area certified organic or in conversion, from the CartoBio plot register.
