National Tree Map

National Tree Map - sample image

Created using recent aerial photography and colour infrared data with high resolution digital surface models, the National Tree Map (NTM™) provides a detailed assessment of tree heights and canopy cover. This dataset is available for the whole of England and Wales and parts of Scotland.

The dataset includes a Tree Crown layer showing crown coverage and maximum, minimum and mean height. The attribution allows a variety of visualisations to be carried out, including classifying tree cover by height or canopy size, filtering out of trees under a certain height, etc.

This ‘off the shelf’ baseline tree inventory cuts out costly and time-consuming field data collection. Although not intended to replace field work, NTM™ will allow field assessors to spend less time collecting the base data and more time collating additional, valuable information on the ground that is not so readily observed from aerial photography.
