- •
Multi-angular vegetation indices (MAVI) for estimating LNC in wheat were developed.
- •
Optimal wavelengths and viewing zenith angles were determined and characterized.
- •
These indices were compared with existing traditional indices.
- •
Our MAVI model improves LNC estimation from remote sensing data by 9.4%.
