ACT Canopy Cover 2020: 1m Resolution Vegetation Map

A geospatial vector dataset of tree canopy cover in the Australian Capital Territory (ACT) at 1-meter resolution. It was created from LiDAR data acquired in April/May 2020 by Aerometrex and processed using DSM/DEM subtraction and NDVI filtering. The dataset represents vegetation above 3 meters tall and is provided by the ACT Government Geospatial Data Catalogue.

Use Cases

• Model urban cooling effects based on canopy cover density.
• Assess urban habitat connectivity based on vegetation distribution.
• Monitor living infrastructure targets based on canopy extent.
• Plan tree planting initiatives based on gaps in canopy coverage.

Strengths

• High-resolution 1-meter spatial detail derived from LiDAR.
• Specific methodology described, including noise removal, building footprint subtraction, and NDVI validation.
• Data acquisition date explicitly stated as April/May 2020.

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 complexity and high resolution.
