ACT Canopy Cover 2020: 1m Resolution Vegetation Map

ACT Government Geospatial Data Catalogue provides a vector dataset of canopy cover polygons for the Australian Capital Territory. The data represents vegetation above 3 meters, derived from LiDAR acquired in April/May 2020 and processed to 1-meter resolution. The dataset is split into districts and 1km tiles for easier viewing.

Use Cases

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

Strengths

• High-resolution 1-meter data derived from LiDAR.
• Specific methodology described, including noise correction, building footprint removal, and NDVI validation.
• Data is available in multiple formats including vector (GPKG, GEOJSON) and raster derivatives.

Limitations

• The dataset may draw slowly or appear to miss some trees due to complexity and high resolution.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
