Such data are even more important where, as in the European Community, a common agricultural policy is one of the important aims. Considerable differences between European countries concerning agricultural production have led to a complex system of rules and subsidies which all rely on a certain level of precision of agricultural statistics. Remote sensing seems to be the most promising technique for upgrading the agricultural statistics system. To obtain rapid improvements, while avoiding duplication of work and a diversity of methods, the Commission has set up a Pilot Project to introduce remote sensing into the European Community agricultural statistics system. The Joint Research Centre is in charge of this project, the objectives being defined according to the priorities of Directorate General VI - Agriculture, and the European Communities Statistical Office. The first requirement is to distinguish, identify and measure the area of important crops. The second is to estimate production in good time so that decisions can be made. When these basic statistics are available, predictions of crop production can then be made. Note de contenu : 1. Introduction 2.
