Bluesky is helping electricity companies ensure their power networks are resilient to the threats from falling trees and overgrown vegetation with its digital tree map data, known as ProximiTREE.

“By helping electricity companies to identify at-risk sections of the network and actively plan their vegetation management activities, we are shifting the approach from the usual reactive emergency response to a tactic that is proactive and planned,” said Alison Riding, team manager for environmental informatics at ADAS, a U.K.-based agricultural and environmental consultancy. “This has positive financial implications as the costs of achieving resilience are clearly delineated for each portion of the network, which also improves customer service and helps companies comply with newly introduced legislation.”

Using Bluesky’s ProximiTREE data, ADAS is able to automatically analyze electricity networks. Advanced geospatial analysis is used to identify specific sections where tree pruning and cutting activities should be prioritized. Once the routes have been selected, the next stage is to carry out a survey to assess the likelihood of trees falling across lines in severe weather conditions.

ProximiTREE is derived from aerial photography. Using overlapping images, the exact location of every tree can be mapped and the height and extent of its canopy derived. ProximiTREE is suitable for use in most desktop Geographical Information Systems (GIS), web mapping applications and Computer Aided Design (CAD) packages. Both 2D and 3D versions of the map are available.

ProximiTREE works alongside existing Bluesky datasets such as 3D buildings, terrain models and aerial imagery.
