Why is it essential for a Geometrician to intervene in a winery?

Read here the interview of Mr Martin, Geometrician and Wi&ne association member.

What can be the tasks of a geometrician in a winery ?

Since the highest antiquity, in Egypt, in Rome or among the Hebrews, it has always been necessary for the man to declare his property and designate him in addition to his name, by his countenance, his nature and his quality, in order to fulfill a tax.

Then were the first technicians of the measurement, the “Agrimeters “, “field measurers”, the surveyors, the geometers, now the Expert Geometers, to help the landowners in these tasks of parcel identification.

They found themselves, by their profession, at the heart of all procedures involving the legal and technical status of lands.

The legislator in 1946 at the time of the creation of the Order of Land Geometers-Experts, entrusted to the profession an exclusive delegation of public service on the delimitation of land properties and consequently on the survey of parcels.

The expert surveyor has become an indispensable player in relations between the State and the landowner.

Its constant, role, in the definition and evolution of the property, right demonstrates the necessary association of the control of the Law, and the technique that he can implement in the context of a management of a wine property.


Can you give us an example?

In fact, this knowledge can be applied in the context of an acquisition project, or on the occasion of the completion of a contract, or at the time of the execution of the various administrative formalities that must be carried out by the vine-grower at Services of the Customs Administration and in application of Community regulations.

Let’s take the case of the following 2 statements:

– Declaration of plantings:

Reminder: this declaration registered in C.V.R. (Computerized Vineyard Register) from D.G.D.D. summarizes for all the parcels of a wine property the communal designation, the cadastral identification, the area of the parcels and the nomenclature of the grape varieties.

-Declaration of planting, Declaration of grubbing

Reminder: prior declaration to the administrative and fiscal services in order to obtain permission to plant or remove a specified area

These two types of declaration require, from the cadastral references, parcels to inform about areas, and to know how to define or identify the surface of a viticulture plot planted with vines.

Hence the need to differentiate between the area exploited – cadastral area – vineyard area – vine area – cultivated area – cultivation area or “pure culture” – real planted area – surface “flush with the stumps”. Article 75 of Regulation (EC) No 555/2

This calculation of area is simple when the small island of plantation integrates as a whole the form of a cadastral parcel (see plan #1). This already becomes more complex when the small island of plantation integrates only part of a cadastral parcel, because then intervenes the notion of the surface area, thus including in addition to the planted area, the plantation, the necessary information for the good exploitation of the vineyard, such as headlands or paths and ditches.

As for the calculation of area in the case of a plantation small island partially implanted on several cadastral parcels, it can be complex and source of error (see plan #2).

Today many winemakers use our know-how, to assist them in the control of their CVR and the establishment of these administrative declarations. The property assessment is made from an inventory.

Why is it so important to check this C.V.R. ?

Simple as this total surface area will have to be mentioned at the end of November on the Harvest Declaration.

Reminder: Tax return to be submitted before 25th of November, of the harvest year, indicating the exact quantities harvested and the areas exploited to control the yields that condition the volumes up started on the market.

An erroneous surface declaration can create both declarative and contractual difficulties and affect the production potential of the buyer or taker.

Can we be controlled and by whom?

The reliability of the CVR is part of the permanent mission of the Customs Administration and is reflected in the on-site verification of wine growers’ declarations.

A contradictory approach is favored during the field control, which allows the winemakers to provide the Customs officers with indications that they consider as relevant.

The chosen area may include certain elements, such as headlands, private roads, embankments and ditches, when they are necessary for the good management of the vineyard, and justified by the configuration of the land.

Even if in the field the appreciation of the surfaces is left to the discretion of the controllers, the assistance of the Geometer-Expert, during the analysis of observations by the Administration, may shed some light, another interpretation given the degree of random precision of the reference documents. It is important to remember that the control tools used such as GPS, aerial photos, despite their high technology, are sometimes far from harmonizing with cadastral plans built in the early twentieth from a Napoleonic Cadaster, established in mid-nineteenth.

These CVR checks differ from the checks carried out in the context of the payment of Community Funds, which focuses on the measurement of areas planted with vines “flush with strains” Article 75 of Regulation (EC) No 555/2008. In accordance with Community Regulation, measurement differences are managed in this case, not at the plot level, but at the farm level.
