Private individuals or unknown: 4.31 ha.

Share of the delimited hectares. Only legal entities are public in France; everything else stays unnamed. From the public register of legal entities (DGFiP), as of 1 January 2025. The owner is not always the one who works the vineyard: tenancy is common.

In the same village, measured between label points. That does not say which ones border each other; the map shows that.

Where each figure comes from

Classification

The INAO delimitation per denomination, cut against the cadastral parcel. Only the INAO's own plans are legally binding; this map is informational.

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.

Slope

Per-cell slope from the elevation model using Horn's method, then averaged over the cells in the polygon.

Aspect

Vector mean of the per-cell aspect. A plain average would turn north-east and north-west into south.

Sun at harvest

Hours of direct sun on 20 September under a clear sky, with the horizon in 36 directions out to six kilometres and the height of woods and buildings on top of it. Canopy height is measured where LiDAR HD covers the area and estimated from BD Forêt where it does not; the panel states which of the two was used.

Grape variety by appellation

Per appellation and colour the permitted varieties from the approved cahier des charges; per appellation and tier the declared hectares of white and red from the customs harvest declaration (product codes). One colour permitted: the main variety of that colour. Two colours: from 85 percent of the hectares that colour applies, in between it is called mixed. Champagne: the dominant variety from the planted hectares per variety per commune from FranceAgriMer. Per polygon the dominant variety of its parts by area. Derived, not measured: the variety per plot exists only in the customs vineyard register, which is not public. In a two-colour appellation a single plot may carry the other variety. Customs withhold small appellations (statistical secrecy), in which case the split is missing.

Bedrock

The geological unit covering the largest share of the polygon, from the 1:50,000 geological map. At 1:50,000 the map separates one climat from another, but not what varies inside a climat.

Organic

Share of the area certified organic or in conversion, from the CartoBio plot register.
