National Tree Map

Trees play a vital role in day to day life – improving the air we breathe, providing valuable habitats for our wildlife, and conserving energy by naturally cooling nearby buildings. However, they also pose a risk to properties, networks and subterranean assets, by causing subsidence or pipeline fractures through root damage, and endangering overhead lines through trees falling and loose branches. It is therefore essential that those involved in tree and vegetation management have access to the most accurate and comprehensive tree mapping data available. This tree mapping data is available as part of the National Tree Map, using both traditional mapping along with aerial and satellite imagery. The attributes that this data provides can then be expanded into 3D geometry.

What is Bluesky's National Tree Map?​
​​

The National Tree Map is a detailed tree mapping dataset providing accurate information about tree locations, heights and canopy coverage across Great Britain. Created using aerial imagery, satellite imagery and height data, it provides a comprehensive view of individual trees and woodland areas for use in GIS, planning and environmental analysis.

​

The dataset identifies trees taller than 3 metres and provides detailed information about their location, height and crown or canopy extent. This allows professionals to understand existing vegetation coverage and assess the impact of trees on proposed developments, infrastructure projects and land management decisions.

​

The National Tree Map provides detailed vegetation and woodland data to support environmental analysis, planning applications and early stage site assessment where understanding existing tree coverage is important. The National Tree Map functions as an add-on to the OS MasterMap, giving you additional vegetation data alonside detailed mapping.​

​

The National Tree Map can be used alongside other geospatial datasets to support more comprehensive site analysis and planning workflows. When combined with aerial imagery, height data and field boundary information, it helps provide a clearer understanding of vegetation coverage, land use and environmental constraints across a site.

​

How is National Tree Map data created?
​

National Tree Map data combines advanced aerial and satellite imagery with height datasets to identify and analyse tree coverage across Great Britain.

​

The data captures key characteristics including:

  • Tree location

  • Tree height

  • Canopy/crown extent

  • Vegetation coverage

​

This enables users to analyse trees at a national scale while still having detailed information suitable for individual sites and projects.

​

Why use tree mapping data from the National Tree Map

  • Tree management (including tree preservation orders)

  • Insurance and risk assessment

  • Flood and pollution monitoring

  • Transport infrastructure, e.g. railway lines • Utility and energy infrastructure

  • Town and city planning

  • Forestry

  • Ecology

  • Air quality monitoring

  • Land and estate management

Applications of National Tree Map Data
​

  • Planning and development: Tree mapping data helps planners and developers understand existing vegetation before beginning projects, supporting site assessments and environmental considerations.

  • Infrastructure and utilities: Trees can present risks to transport networks, power infrastructure and underground utilities. Accurate tree location and height data supports better risk assessment and maintenance planning.

  • Forestry and woodland management: Tree canopy information helps organisations monitor vegetation, manage land assets and understand woodland coverage.

  • Ecology and environmental analysis: Tree mapping supports biodiversity studies, habitat assessments and environmental monitoring.

​
