During 2008 an experimental study aimed to investigate the capabilities of a new Airborne Remote sensing platform as
an aid in precision viticulture was conducted. The study was carried out on 2 areas located in the town of Velletri, near
Rome; the acquisitions were conducted on 07-08-2008 and on 09-09-2008, using ASPIS (Advanced Spectroscopic
Imager System) the new airborne multispectral sensor, capable to acquire 12 narrow spectral bands (10 nm) located in
the visible and near-infrared region. Several vegetation indices, for a total of 22 independent variables, were tested for
the estimation of different oenological parameters. Anova test showed that several oenochemical parameters, such as
sugars and acidity, differ according to the variety taken into consideration. The remotely sensed data were significantly
correlated with the following oenochemical parameters: Leaf Surface Exposed (SFE) (correlation coefficient R2 ~ 0.8),
wood pruning (R2 ~ 0.8), reducing sugars (R2 ~ 0.6 and Root Mean Square Error ~ 5g/l), total acidity (R2 ~ 0.6 and
RMSE ~ 0.5 g/l), polyphenols (R2~ 0.9) and anthocyanins content (R2 ~ 0.89) in order to provide "prescriptives"
thematic maps related to the oenological variables of interest, the relationships previously carried out have been applied
to the vegetation indices.
