Spatial characterization of land use in the viticultural Maipo Valley (Chile), using aster image digital processing


[English version below]

L’entreprise viticole Concha y Toro S.A. gère environ 600 ha de vignes dans la Vallée du Maipo (A.O. Valle del Maipo). L’objectif est celui de caractériser spatialement ces vignobles et leur occupation du sol environnante. Le choix s’est porté vers la démarche de zonage viticole par l’analyse spatiale, utilisant des traitements d’images satellitaires afin d’avoir une vision synoptique de la zone à moindres coûts et délais. Un système d’informations géographiques (SIG) est construit à partir des données suivantes : cartes topographiques, géologique, fond cadastral numérique, images satellitaires. Un modèle numérique de terrain est par ailleurs construit à une résolution de 25 m à partir des cartes topographiques. Deux images Aster (résolution de 15 m) prises au mois d’octobre 2000 et janvier 2001 ont été choisies. Une cartographie de l’occupation du sol a été effectuée sur l’image satellitaire de janvier nous permettant par ailleurs d’actualiser les cartes topographiques datant de 1974, en raison notamment de l’expansion urbaine de la ville de Santiago en périphérie des vignes. Par ailleurs, l’étude diachronique mise en œuvre conduit à analyser les comportements spectraux des vignes et des sols et leur évolution spectrale entre les deux dates retenues.

Concha y Toro S.A. wine enterprise controls about 600 hectares of vineyards in the Maipo Valley (A.O. Valle del Maipo). Our purpose is to carry out a spatial characterization of vineyards and their surrounding land use, based on spatial analysis and using satellite image processing which enables to get a broad synoptic vision of the area at low cost. A geographic information system (GIS) is built with the following data: topographic maps, geological maps, digital cadastral database and satellite images. A digital elevation model (DEM) is made from the topographic maps at a 25 meters-resolution. Two high resolutions Aster images (15 meters) captured in October 2000 and January 2001 were chosen. Land use is spatially characterized using the January image. It enables us to update the land use cover extracted from the topographic maps and dating 1974, especially because of the urban sprawl of the city of Santiago amongst vines. More, the image diachronic study leads to analyze the spectral behavior of vine and soil and its evolution from January to February 2001.

Vineyard soils and landscapes of the Burgundy Côte (France): a historical construction worth preserving

The construction of vineyard landscapes along the Burgundy Côte is the result of geological processes and of human labour. Substratum diversity in this vineyard is the result of a very long history explained by the diversity of Jurassic sedimentary facies and Tertiary tectonic activity. The nature and thickness of Quaternary deposits (Weichselian scree debris and alluvial fans) reflect sediment dynamics concurrent with the last glaciation.

AOC valorization of terroir nuances at plot scale in Burgundy

In the highly competitive global wine market, Burgundy has a long-established reputation to maintain. The vine and wine sector in Burgundy is based on a five-level ranking of AOC (Appellation d’Origine Contrôlée) wines and of the plots where the grapes are grown.

The revision of the delimitation of the AOC “Champagne”

The Champagne vine-growing region has played a pioneering role in the delimitation of appellations of origin (AOC). The implementation of the Act of July, 22nd 1927 has led to drawing up lists of vine plots based on the criterion of vine cultivation antecedence.

Building of a hierarchy of wines based on terroirs: an initiative from the producers of Muscadet

The Muscadet area is situated in the southeast of Nantes, close to the Atlantic coast. It constitutes the western extension
of the French vineyard “Loire Valley”. The Muscadet is renowned and often spontaneously linked to a white wine.
However it remains misconceived as an ordinary wine, lacking authenticity.

How the physical components of the terroir can differently intervene in French wines DPO definitions.Example of Côte de Nuits in Burgundy

European regulations describe what elements must be given in the specifications of DPO determination ; mainly production conditions, links between quality and products characteristics and the physical traits of the production area. These elements are given in the “link to terroir” paragraph relating natural and human factors, detailed product characteristics linked to the geographical area and at last interactions between product originality and the geographical area.
