The agricultural sector is really important in the definition of the social and economical management politics of the territory. Therefore it is fundamental to have analysis tools that allow to know the territory deeply, taking into account the complex relationships existing between its elements. Remote Sensing and Geographic Information Systems are a valuable support tool in this sense, because they allow on one side to collect territorial data in a logic and structured way and, and on the other side, to establish analysis methodologies for the planning of the interventions.
Remote sensing allows to evaluate crop illness quickly, but it furnishes also input data necessary for a good deal of applications such as: analysis of fertility, soil moisture, aimed at the forecast of crop growth. The adoption of a GIS could constitute a valid support to the actions of producers' assistance.
