Carlisle City Council is using the Bluesky ProximiTREE data to map existing trees, highlight areas where additional planting may be required, identify possible risks posed by trees and inform their inspection regime. ProximiTREE is an accurate map representation and database of tree heights and their canopy widths derived from aerial photography. Bluesky’s team of editors, trained in accurate photo-interpretation, examines aerial photos to identify the height of all crown and canopies visible within each photo. Once the highest point of each tree’s crown has been measured, actual tree heights are determined using an existing Digital Terrain Model (digital representation of ground surface topography or terrain).
