Bluesky strengthens data-led tree management with new UK-wide datasets

Aerial survey specialist Bluesky International, a Woolpert company, has introduced two new datasets designed to significantly enhance how trees across the UK are mapped, monitored and managed.

Building on its established National Tree Map (NTM), Bluesky has launched NTM+ and NTM Risk, expanding the depth, context and timeliness of tree intelligence available to public and private-sector users. With the option of monthly updates for both new products, the datasets are positioned as the most current source of tree attribute information currently available in the UK.

“For over a decade, the National Tree Map has been the go-to resource for organizations seeking reliable tree data,” said Ian Dee, associate director R&D and innovation at Bluesky. “These new releases take that to the next level, giving our customers deeper insight, faster updates and data tailored to real-world needs.”

Contextual information

NTM+ extends traditional tree mapping by linking each mapped tree to a wide range of contextual information. This includes precise locational references such as the nearest Unique Property Reference Number (UPRN), postcode, Lower Layer Super Output Area (LSOA), district and county, alongside conservation designations covering Sites of Special Scientific Interest, Areas of Outstanding Natural Beauty, Special Areas of Conservation, National Parks and Greenbelt land. The dataset also integrates land use classifications, spanning residential, industrial and agricultural areas, as well as soil and agricultural information such as soil type, drainage characteristics and Agricultural Land Classification grades.

By combining tree location data with this broader environmental and administrative context, NTM+ is intended to support faster and more informed decision-making across sectors including local government, utilities, insurance and property, all through desktop-based analysis.

How trees interact with surrounding assets

Complementing this, NTM Risk focuses on quantifying how trees interact with surrounding assets, people and infrastructure. The dataset provides insight into potential hazards by analysing factors such as the distance between trees and nearby buildings, tree height, fall radius and the number of properties potentially affected. It also assesses proximity and orientation relative to road and rail networks, nearby rivers and watercourses, and incorporates wind data, including seasonal averages and predicted future speeds based on climate change scenarios. Elevation data, including ground height above sea level, supports flood risk analysis, alongside classifications for recognized flood zones.

Together, the two datasets aim to give users a clearer picture of both tree context and potential risk, supporting planning, maintenance and risk management activities.

Alongside the new product launches, Bluesky is continuing to invest in research and development through a Knowledge Transfer Partnership with the University of Leicester. The 24-month collaboration is focused on improving tree species identification within the wider National Tree Map suite.

“We’ve listened closely to customer feedback to evolve the NTM platform,” added Ian Dee. “NTM+ and NTM Risk directly address industry pain points, reducing project time, increasing precision and delivering immediate, actionable insight.”
