Cambridge City Council has used a digital map of trees, created by aerial mapping company Bluesky, to inform tree planting and management.
As part of a wider project to address the effects of climate change the specially commissioned ProximiTREE data replaced a more traditional tree audit to determine which trees already existed and where they were located. Derived from aerial photography the Bluesky tree map details the exact location of all trees and includes measurements of tree height and canopy extent.
“In order to determine the most appropriate areas for additional tree planting we needed to understand what we already had and where it was located,” commented Matthew Magrath, Tree Officer at Cambridge City Council. “The ProximiTREE data provided an excellent base further analysis.”
ProximiTREE is derived from the most accurate and up to date aerial photography. Using overlapping images the exact location of every tree can be mapped and the height and extent of its canopy derived. It 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 and it works alongside existing Bluesky datasets such as 3D buildings, terrain models and aerial imagery.
