ACT Canopy Cover 2020: 1m Resolution Vegetation Map

The Australian Capital Territory (ACT) canopy cover map delineates vegetation above 3 meters at 1-meter resolution. It was derived from LiDAR data acquired in April/May 2020 by Aerometrex and processed using a detailed methodology involving DSM, DEM, CHM, and NDVI layers. The dataset is provided by the ACT Government Geospatial Data Catalogue.

Use Cases

• Model urban cooling effects based on canopy coverage.
• Assess urban habitat connectivity based on vegetation polygons.
• Plan living infrastructure projects based on high-resolution canopy location.
• Validate remote sensing algorithms based on the described LiDAR and NDVI processing methodology.
• Calculate district-level canopy statistics based on the provided vector polygons.

Strengths

• High-resolution 1-meter spatial detail for canopy polygons.
• LiDAR data acquired in April/May 2020 with an average resolution of 12ppm.
• Processing methodology is explicitly documented, including steps for noise removal, building footprint exclusion, and NDVI correction.

Limitations

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