ACT Canopy Cover 2020 at 1 Meter Resolution

Canopy cover polygons for the Australian Capital Territory derived from LiDAR data acquired in April/May 2020. The dataset represents vegetation cover above 3 meters in height and has been processed into district-based and 1km tile vector formats. It was created by the ACT Government using data from Aerometrex.

Use Cases

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

Strengths

• High-resolution 1-meter data derived from LiDAR with an average resolution of 12ppm.
• Methodology includes removal of non-vegetative surfaces using NDVI and building footprints.
• Available in multiple formats including vector (GPKG, GEOJSON) and raster derivatives.

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.
