Advanced satellite technologies offer new opportunities to address these issues. In 2010, the GrapeLook project was initiated, providing information on crop water, growth and nitrogen status during the growth season using satellite data. The first demonstration year provided users with a deeper insight into the temporal and spatial processes in vineyards to improve water productivity.
