SAGIRA project has developed a system to analyze information from farming sensors, georeferenced, with specicialised stock and with an interface display which show the result data overprinted on the real images (augmented reality with mobile devices). This technology allows users to make relations between elements, not only pay attention on characteristics of them, as historically. Furthermore, users can check data using these relations and attributes. It is useful to optimization of water resources in crops and pesticides and fertilizers.
