Estimation of canopy parameters for inhomogeneous vegetation canopies from reflectance data

Abstract
A canopy-reflectance (CR) model for row-planted vegetation is presented. Its use for an estimation of important biophysical variables like leaf-area index (LAI) and average leaf angle (ALA) from bidirectional CR data is discussed. Using field-measured CR data for a partially covered soybean canopy, it is shown that one can accurately estimate LAI, ALA and extent of percentage of ground cover from CR data. Row canopy reflectance
