Figure 1. Performance of different vegetation indices (Vi's) as winter wheat
LAI predictors, using the normalized deviation (DEVn.r.) from measured LAI as
criterion. Results of Vi’s yielding significant differences between measured
and estimated LAI are not displayed. Bar charts on the left and on the right
refer to LAI estimation in the pre-senescence and post-senescence period
respectively. The rows of bar charts refer to normalisation procedures for
solar zenith angle. The reader is referred to the text for the explanation of
the acronyms.
