Abstract
Oenoview® was born in 2006 from the partnership between the GEO-Information division of Astrium Services specialized in earth observation and the Institut Coopératif du Vin (ICV), a French wine and vine services company.
Oenoview® is an operating precision viticulture service, dedicated to vine monitoring, harvest optimisation and input management.
Launched in France in 2009 on a commercial scale, this service is now used on more than 15.000 ha by various kinds of wineries including large cooperative wineries and famous chateauxs in France but also abroad (Morocco, Greece, Japan, etc.). The Oenoview® service provides the winegrower and vineyard consultant with a bundle of maps and customized recommendations before harvest.
These products are designed to support decision making processes along the year, more especially at the most critical stage of the vine growing process, the harvest.
High resolution satellite images (Spot5, Formosat2) are processed by Astrium Services processing chain to produce maps quantifying the vine vigour and the field heterogeneity.
These maps, based on biophysical parameters provided by Astrium Services proprietary software OverlandTM are analyzed and interpreted by consultants (ICV or distribution network) to support winegrowers in their decisions.
A specific zoning method has been developed, which leads to within-field zones based on objective limits, the same for different vineyards.
Two to 10 different zones can be identified inside a same vineyard, according to their intra-field variability and to the required zoning precision.
The maps can be used by GPS guided machines for harvest or fertilization, as proved by different field tests realized since 2009. It is thus possible to separate grapes according to their quality in a group of vineyards, and produce different wine styles, or to adapt the fertilization to the effective vine requirements in different parts of a block.
Grape selection can also be improved on a large scale, due to field selection schemes based on vigor and intra-field variability.
