ACT Tree Canopy Cover Map at 1m Resolution, 2020

Australian Capital Territory (ACT) canopy cover polygons at 1-meter resolution, representing vegetation above 3 meters as of April/May 2020. The dataset was derived from LiDAR data acquired in April/May 2020 by Aerometrex and processed using a detailed methodology involving DSM, DEM, CHM, and NDVI layers. It is provided by the ACT Government Geospatial Data Catalogue.

Use Cases

• Analyze urban cooling potential based on canopy cover distribution.
• Map urban habitat connectivity based on vegetation coverage.
• Assess living infrastructure metrics for city planning.
• Validate or supplement individual tree delineation datasets.
• Monitor changes in urban vegetation over time using the 2020 baseline.

Strengths

• High-resolution 1-meter spatial detail for canopy cover.
• Derived from LiDAR data acquired in April/May 2020 with an average resolution of 12ppm.
• Processing methodology is explicitly documented, including steps for noise removal, building footprint subtraction, and NDVI validation.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset may draw slowly or appear to miss some trees due to its complexity and high resolution.
