ACT Canopy Cover 2020: 1m Resolution LiDAR Map

The Australian Capital Territory (ACT) canopy cover map at 1-meter resolution, derived from LiDAR data acquired in April/May 2020. The ACT Government processed the data to represent vegetation above 3 meters, using techniques like DSM/DEM subtraction and NDVI filtering. The dataset is available in multiple vector formats and is split into districts and 1km tiles for easier access.

Use Cases

• Analyze urban tree canopy distribution based on the 1-meter resolution vector polygons.
• Model urban cooling effects using the high-resolution canopy cover data.
• Assess living infrastructure and urban habitat connectivity based on vegetation cover above 3 meters.
• Integrate canopy data with building footprints for urban planning, as mentioned in the processing methodology.

Strengths

• Data is derived from LiDAR captured at an average resolution of 12ppm in April/May 2020.
• Processing includes removal of non-vegetative surfaces using an NDVI layer from 2019 Pleiades satellite imagery.
• Dataset is available in multiple geospatial formats including GPKG, GEOJSON, and GDB.

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, as noted in the warning.
