ACT Canopy Cover Polygons at 1m Resolution for April/May 2020

April/May 2020 LiDAR-derived canopy cover polygons for the Australian Capital Territory, representing vegetation above 3 meters at a 1-meter resolution. The dataset was processed by Aerometrex and the ACT Government, using a canopy height model derived from Digital Surface and Elevation Models. It is available as vector polygons, split into districts and 1km tiles for easier access.

Use Cases

• Analyze urban cooling potential based on canopy cover distribution.
• Model urban habitat connectivity based on high vegetation polygons.
• Assess living infrastructure coverage for district-level planning.
• Validate remote sensing algorithms using processed LiDAR canopy data.

Strengths

• Data is derived from LiDAR acquired at an average resolution of 12ppm.
• Canopy cover is defined for vegetation above 3 meters, providing a clear threshold.
• Processing methodology is detailed, including noise removal and building footprint correction.

Limitations

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