Barracu, Francesco (2013) Variabilità spaziale e temporale di parametri applicati alla Precision Farming in risicoltura. Doctoral Thesis.
Measuring plant biophysical parameters at the field scale can be expensive and time consuming as large amount of sample points and measurements to estimate spatial and temporal variability are necessary. Vegetation indices from remote and proximal sensing could be used to estimate variables linked to canopy properties. Particularly, vegetation indices (VI) from remote sensing provide spatio-temporal information on the entire field canopy variability, overcoming the limitations of sampling field investigation. The development of dedicated algorithms makes the spectral indices computation analysis rather quick. Nowadays, the development of vegetation indices and their application is one of the most important topics in precision agriculture.
