Description: This dataset represents the extent of the City of Cape Town’s Tree Canopy. This dataset was generated in order to provide the Recreation and Parks with a better understating of the extent of; and to aid its management decision making in relation to this green infrastructure.A near infra-red (NIR) imagery dataset was acquired simultaneously with the 2018 aerial imagery. The NIR dataset was then combined into the colour infra-red (CIR) composite where plant health shows up as red. A height mask of ground height to 2.75m and above was then used to remove undesirable features such as lawns and bushes using LiDAR and an auto-correlated DSM. Feature extraction using sample selections were then applied to the CIR to select all vegetation over 2.75m above ground. Input data was packaged into a 5 x 5km grid, comprising of 147 blocks across the City.Data then underwent manual GIS cleaning and quality control based on the 2018 aerial imagery, to remove anomalies from the dataset and to conduct edge-matching along the grid boundaries.
