ACT Tree Canopy Cover Map at 1 Meter Resolution for 2020

LiDAR-derived canopy cover polygons for the Australian Capital Territory represent vegetation above 3 meters tall as of April/May 2020. The ACT Government processed Aerometrex's 12ppm LiDAR data using DSM/DEM subtraction and NDVI filtering to create a 1-meter resolution vector dataset. This map is split into districts and 1km tiles for easier access and viewing.

Use Cases

• Model urban cooling effects based on canopy cover distribution.
• Assess urban habitat connectivity using vegetation coverage polygons.
• Monitor changes in urban tree canopy over time using the 2020 baseline.
• Integrate canopy data with building footprints for urban planning analysis.
• Calculate district-level statistics for living infrastructure reporting.

Strengths

• High-resolution 1-meter data derived from LiDAR with an average 12 points per meter.
• Methodology includes removal of non-vegetative surfaces using NDVI and building footprints.
• Data is 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 resolution.
