This section aims at presenting methods that are currently under developmment and that rises some scientific and or technical problems. It is mainly addressed to engineers or researchers working in the field of the precision viticulture to share methods, knowledge and tools like programs. This section is organized in subject. One of the subject refers for example to the definition of the opprotunity to consider the within field variability. In the future, other subjects will be detailed such as for example : the temporal stability of within field variability, the zone inference, etc.
