Abstract :
The feasibility of estimating leaf size from canopy reflectance in the hotspot region is investigated for both homogeneous (leaf) and heterogeneous (rowed crops and trees) canopies. The authors specify optimal Sun-view geometry, wavelength and index which can minimize the impacts of other structural parameters (e.g. LAI, leaf angle distribution (LAD) and interplant spacing) for most accurate estimation
