Bedrock
- 39%Colluvium, mixed slope deposit about 0.1–0 million years
- 33%Lutetian limestone and caillasses 48–41 million years
- 29%Lutetian sand and Tuffeau de Damery 48–41 million years
Not a borehole: ordered by age, thickness by share of surface.
In the glass. As a group, colluvium says little about flavour on its own. In practice the rounder, earlier-approachable wines often sit on the thicker colluvial fans, while tension and ageing potential are more closely tied to slope, soil depth and vine age. (weak indication)
Not a true formation but a collective name for material that has come down from higher up the slope: limestone scree, lumps of marl, clay and loess, worked together by gravity, frost and rainwater. Most of it was deposited during and after the last ice ages, roughly the past hundred thousand years, and the process is still going on. What exactly is in the ground depends entirely on what lies upslope, so the same map colour can mean something slightly different from village to village.
For the vine. Usually loose, stony and deep, so the roots can go far and surplus water drains away quickly. Thanks to the fine material between the stones, colluvium generally holds more moisture in a dry summer than the thin soil on the bare rock above. At the bottom of the slope the deposit becomes thicker and finer, and because of the low position it is cooler and wetter there; where it contains a lot of limestone scree the active lime content can run high.
Characteristic of the mid and lower slopes of the whole Côte d'Or, including the scree fans at the mouths of the combes, as at Gevrey-Chambertin below the Combe Lavaux.

Clear sky, with the tree canopy from the IGN forest inventory as a raised horizon (15 m closed forest, 5 m heath, trees within 60 m ignored), 47% of the far field is forest (BD Forêt), no buildings.

The name
- croix
- cross. A wayside or boundary cross that served as a landmark. Ownership and saints · Gérard Taverdet, Noms de lieux de Bourgogne (2007)
This is about the words, not about this plot: the same name can have arisen differently elsewhere.

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.
