ACT Canopy Cover 2020 at 1-Meter Resolution

April/May 2020 LiDAR data acquired for the Australian Capital Territory at an average resolution of 12ppm was processed to create a map of district-based canopy cover polygons. The ACT Government Geospatial Data Catalogue (ACTmapi) produced this dataset, which represents vegetation cover above 3 meters. Processing involved creating a Canopy Height Model from Digital Surface and Elevation Models and removing non-vegetative surfaces using NDVI layers.

Use Cases

• Model urban cooling effects based on canopy cover polygons.
• Assess urban habitat connectivity based on vegetation distribution.
• Monitor changes in living infrastructure based on high-resolution canopy data.
• Plan green space development based on district-level canopy statistics.

Strengths

• Data is derived from LiDAR captured at 1-meter resolution, providing high spatial detail.
• Processing methodology is documented, including steps to remove noise, building footprints, and erroneous non-vegetative surfaces.
• Multiple derivative products and formats are available, including canopy height models and individual tree delineations.

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.
