文摘

•: 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.
