Bluesky National Tree Map™ V2 is a vector database of tree location, height and crown/canopy extents for trees above 3m in height across UK. The product improves situational awareness where trees might represent health and safety hazard or hamper operational activities (e.g. railways, traffic management, routing of high-sided vehicles, road and building maintenance, siting of mobile phone masts, site development), for facilities managers with grounds maintenance responsibility and public sector bodies with environmental obligations. It also informs planning and development strategies to help prevent loss of or damage to ancient woodland, local trees and biodiversity. Bluesky National Tree Map™ V2 is updated regularly as new aerial photography becomes available and the product is compatible with Ordnance Survey products and with other Bluesky products to make 3D visualisations.
