A high resolution map of tree canopy cover for Greater London was produced from aerial imagery using machine learning techniques. The map was produced by Breadboard Labs in collaboration with the Greater London Authority as part of a Breadboard Lab’s European Space Agency funded project, Curio Canopy .
The algorithms and machine learning based techniques used to produce the canopy map were developed using Google Earth Engine which was also leveraged to perform the processing needed to create a pan-London high resolution (25 cm per pixel) tree canopy data. Full details of the methodology are documented here.
Final canopy layers have been made available to download below in a geospatial format (KML).
The pan-London high resolution canopy layer has also been aggregated to: hexagon grid, Lower Super Output Area (LSOA), Ward (2014) and London Borough geographies.
