Bluesky’s National Tree Map™ (NTM™) is the most detailed dataset of its kind ever produced. With coverage across the whole of England and Wales, NTM™ provides a unique, comprehensive database of location, height and canopy/crown extents for every single tree 3m and above in height. Bluesky’s National Tree Map is created using innovative algorithms and image processing techniques in combination with the most up to date and detailed aerial photography.
In addition to the three vector map layers; Crown Polygons, Idealised Crowns and Height Points, the Bluesky National Tree Map also includes an attribute table including unique identification for each crown feature, height attributes and area calculations.
The data is available in a range of GIS-ready formats on Bluesky’s online Mapshop alongside the most up to date aerial photography, accurate height data and 3D building models.
