In order to improve the wine quality a study has been carried out on a vineyard. From two different types of satellite images, 5 products have been obtained and represented in maps. DMC-UK images, with a resolution of 32 meters and QUICK-BIRD images, with a resolution of 0.6 meters have been used. Through the bands of these images, the following products were obtained: the NDVI, with which users find out which zones in their estates have the worst condition; Mean Vegetation State, which is a comparative map resulting from the comparison between the NDVI of each pixel and the average NDVI in the area of study; LAI, which provides information on the foliar area of plants (this is very important in the case of grapes since it is directly related to the number of clusters the plant will give); BIOMASS, which provides information on the quantity of living organic matter in the plant and a representative NITROGEN map useful in fertilizing and nitrogened tasks. In spite of their different resolutions, the comparison between the images obtained through both types of images provides very similar data.
