Abstract :
A method based on radiative transfer models (RTM) incorporating multi-angle data is used to estimate LAI. The estimation of LAI from inversion will be based on Look Up Tables (LUT) approach. The usefulness of the method was verified using the data of Spectral database of Chinese typical features. The determination coefficient R2 between estimated result and measurement data is high to 0.6046. The outcome of the method in this article is acceptable.
