Les outils de télédétection au service d'une gestion intra-parcellaire.

Abstract : In vineyard management, the block is today considered as the technical work unit. However, considerable variability can exist inside a block with regard to physiological parameters, such as vigour, particularly because of soil heterogeneity. To represent this variability spatially, many measurements must be taken. That is costly in both time and money. High resolution remote sensing appears to be an efficient tool for mapping intra-block heterogeneity. A vegetation index, the Normalized Difference Vegetative Index (NDVI), calculated with red and near infrared leaf reflectance can be used as a vine vigour indicator. Because of the cultivation of vines in rows, a specific image treatment is needed. Only high resolution remote sensing (pixels less than 20 cm per side) allows the discrimination between row pixels and inter-row ones. The significant correlation between NDVI and pruning weight demonstrates the possibility to map the vigour with the NDVI by means of high resolution remote sensing, and consequently to explain the variations of linked quality factors.
