dc.description.abstractCanopy light interception constitutes an important yield limiting factor in high density olive orchards. However, its characterisation still implies laborious measurements. A new index, the Leafiness-LiDAR index (LLI), is presented as a LAI estimator. LLI combines LiDAR-derived parameters: Cross-Section and Leafiness from 3D point clouds. To validate the results, photosynthetically active radiation (PAR) measurements, canopy volume, yield and quality parameters were collected and analysed. LLI showed significant correlations both with PAR and canopy volume (r = 0.8) and quality parameters (r = -0.6). LLI may be useful as an early decision canopy monitoring tool in the framework of Precision Fructiculture.
