• Resumen

  • Since 1999 several commercial satellites capable of taking very high resolution images, have had the capacity to obtain information about any object on the earth's surface larger than 60 cm. Such satellites orbit the Earth and supply customized information (the user chooses how, when and where the satellite acquires the image). The satellite images record the interaction between vineyards by means of the electromagnetic radiation of the visible and near-infrared regions of the electromagnetic spectrum. These interactions are directly related to the greenness of the plants, the photosynthetic activity rate and the biomass of the plant.

    Information from satellite images can be immediately used to improve vineyard management because it allows us:

    i) To assess the current variability of exploitation during critical periods of vegetative growth, and ii) To establish areas with homogeneous characteristics in their exploitation Information obtained before harvesting allows improved planning of the work and a more selective way of carrying out the process.

    An integrated analysis, using data from the plant-climate-soil sensors and information from satellite images, provides continuous spatial-temporal information for agricultural management aiming to achieve greater homogeneity of the area under cultivation.
