2.5.3. Fractional Cover (*fc*) and Canopy Width (*wc*)

The north and south vineyard blocks were classified into two categories, vine and interrow, based on *NDVI*. Then the vine area inside each spatial domain was calculated and divided by the total area of the grid to calculate the *fc*. *w<sup>c</sup>* inside each spatial domain was computed using *f<sup>c</sup>* and the width of the grid (*w*) under analysis, i.e., *w<sup>c</sup>* = *f<sup>c</sup>* × *w*. To calculate the representative width of the vine canopy, the total width was rescaled and standardized at multiple spatial domain scales, depending on the number of rows inside each grid. For example, in the case of a 3.6-m grid, one vine row was counted inside, while in a 7.2-m grid, the number of rows was doubled.
