ACT Canopy Cover Extent at 1m Resolution, April/May 2020

April/May 2020 LiDAR-derived canopy cover polygons for the Australian Capital Territory, processed at 1-meter resolution. The ACT Government created this dataset by classifying vegetation above 3 meters, removing noise and non-vegetative surfaces. The data is split into districts and 1km tiles for easier viewing.

Use Cases

• Analyze urban cooling potential based on canopy cover extent.
• Map urban habitat connectivity based on vegetation polygons.
• Assess living infrastructure coverage for policy planning.
• Validate or supplement individual tree delineation datasets.
• Model permeability or shade patterns in urban areas.

Strengths

• High-resolution (1m) canopy cover polygons.
• Derived from LiDAR data acquired at an average resolution of 12ppm.
• Processed using multiple validation layers (building footprints, NDVI) to remove errors.

Limitations

• 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 complexity and high resolution.
• Row count is unknown, which may limit suitability assessment.
