ACT Tree Canopy Cover Map at 1 Meter Resolution, 2020

LiDAR data acquired in April/May 2020 at an average resolution of 12ppm was processed to create a map of vegetation cover above 3 meters for the Australian Capital Territory. The dataset is provided as district-based polygons and 1km tiles for easier viewing. It was produced by Aerometrex under contract for the ACT Government.

Use Cases

• Analyze urban tree canopy coverage for climate resilience planning based on the 1-meter resolution canopy cover polygons.
• Model urban cooling effects based on the high-resolution vegetation cover data.
• Assess changes in urban habitat connectivity based on the delineated canopy areas.
• Integrate canopy data with building footprints for urban development impact studies based on the building footprint layer used in processing.

Strengths

• Data is derived from high-resolution LiDAR (12ppm) and processed to 1-meter resolution.
• Processing methodology is detailed, including steps to remove noise, building footprints, and non-vegetative surfaces.
• Dataset is available in multiple formats (e.g., CSV, GPKG, GEOJSON) and split into districts and tiles for accessibility.

Limitations

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