ACT Canopy Cover 2020: 1m Resolution Vegetation Map

April/May 2020 canopy cover polygons for the Australian Capital Territory, derived from LiDAR data. The dataset represents vegetation above 3 meters and is processed into vector polygons at 1-meter resolution. It was created by Aerometrex under contract for the ACT Government.

Use Cases

• Model urban cooling effects based on canopy cover distribution.
• Assess urban habitat connectivity based on vegetation polygons.
• Plan living infrastructure projects based on high-resolution canopy location data.
• Validate or supplement other environmental datasets like permeability or shrub cover.

Strengths

• Derived from LiDAR data acquired at an average resolution of 12ppm.
• Processed using a detailed methodology including DSM/DEM subtraction, building footprint removal, and NDVI filtering.
• Available in multiple formats including vector (GPKG, GEOJSON) and raster derivatives.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset may draw slowly or appear to miss some trees due to its complexity and high resolution.
