WCC Tree Canopy Heights

This dataset provides boundaries for trees in Wellington, New Zealand. The area for which tree cover boundaries are provided corresponds to the area covered by the city's Green Network Plan. Tree cover is a 2D representation of the outline of a tree which has been classified from LINZ aerial imagery (acquired in the summer of 2016-17) and lidar data (acquired in the summer of 2019-2020) using a combination of automated and manual processes to identify and delineate trees. Trees were considered to have a minimum height of 3.5 m and a minimum diameter of 1.5 m. Because of this definition, this tree cover dataset may contain large shrubs or other tall forms of vegetation. Where trees exceeded 7 m in height, a maximum height was determined from lidar data and assigned to that polygon. Because polygons include one or more trees, the height associated with a polygon means that at least one tree within that polygon has that height.
