ACT Canopy Cover 2020 at 1 Meter Resolution

LiDAR data acquired in April/May 2020 at an average resolution of 12ppm was processed to create a vector dataset of canopy cover polygons for the Australian Capital Territory. The dataset represents vegetation above 3 meters, with building footprints and NDVI layers used to refine the results. It was produced by the ACT Government Geospatial Data Catalogue (ACTmapi) and last updated in April 2026.

Use Cases

• Analyze urban cooling potential based on canopy cover distribution.
• Map urban habitat connectivity based on vegetation polygons.
• Assess living infrastructure coverage for policy planning based on district-based canopy data.
• Validate or supplement individual tree datasets using the high-resolution canopy model.

Strengths

• Data is derived from LiDAR captured at an average resolution of 12ppm, suggesting high spatial accuracy.
• Processing methodology is detailed, including steps to remove non-vegetative surfaces and fill canopy holes.
• The dataset is split into districts and 1km tiles for easier viewing and analysis.

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 description warns that due to complexity and high resolution, the dataset may draw slowly or appear to miss some trees.
