ACT Tree Canopy Cover Polygons Derived from 2020 LiDAR

April/May 2020 LiDAR data from Aerometrex was processed to create a 1-meter resolution map of vegetation cover above 3 meters for the Australian Capital Territory. The dataset consists of district-based canopy cover polygons, derived from a canopy height model and cleaned using building footprints and NDVI layers. It is provided by the ACT Government Geospatial Data Catalogue.

Use Cases

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

Strengths

• Derived from LiDAR data acquired at an average resolution of 12ppm.
• Processing methodology includes removal of non-vegetative surfaces using building footprints and NDVI.
• Canopy holes smaller than 1 square meter were filled.

Limitations

• The description warns that due to complexity and high resolution, the dataset may draw slowly or appear to miss some trees.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
