•
0.5 meter resolution canopy height maps at jurisdictional scale are re-
leased.
•
Improved performance from Self-Supervised Learning (SSL) and vision
transformers.
•
First use of SSL and vision transformers for canopy height estimation.
•
Low resolution GEDI and high resolution aerial lidar predictions are
combined.
•
Model generalises well to aerial imagery, even though trained with satel-
lite images.
