Mapping London's Trees & Tree Cover

The London Tree Canopy Cover interactive map provides a high resolution view of tree canopy cover in the Greater London area.

The map was created by a European Space Agency funded project called Curio Canopy. Curio Canopy uses machine learning based techniques to identify tree canopy cover from ESA satellite imagery. The project also uses crowd-sourcing to get citizen science volunteers to check the results on the ground. These checks are then fed-back into the system to improve the system's image recognition algorithms. You can read more about how Curio Canopy identifies tree canopy cover in their methodology report, Measurement & spatial analysis of London’s tree canopy cover (PDF).

London has over 8 million trees. You can learn more about some of those trees on the Greater London Authority's London Tree Map.  This interactive map shows the locations and genus of 700,000 of London's trees.
