BRANCH advances how urban green spaces are mapped, understood, and related to public health. It develops a multi-scale, health-oriented typology that combines ecological structure, spatial composition, visibility, and accessibility. The project uses optical, hyperspectral, LiDAR, and SAR remote sensing; AI-powered image analysis; proximal sensing; and citizen science to produce high-resolution functional green-space maps. These maps will support research into relationships between urban greenery, health outcomes, and healthcare use, and inform planning and public-health practice.
