- •
Summer and autumn seasons LandSAT-5 images yielded highest single season accuracies.
- •
Spectral vegetation indices and image textures provided minimal improvement.
- •
L-band performs better than optical datasets at retrieving woody cover in savannahs.
- •
Integration of LandSAT-5 and L-band data does provide a significant improvement.
