ACT Tree Canopy Cover Map at 1m Resolution, April/May 2020

Australian Capital Territory (ACT) canopy cover polygons at 1m resolution, representing vegetation above 3m height as of April/May 2020. The dataset was derived from LiDAR data acquired by Aerometrex and processed using ArcPro tools, with building footprints and NDVI layers used to refine results. It is provided by the ACT Government Geospatial Data Catalogue.

Use Cases

• Analyze urban tree canopy distribution based on the 1m resolution vector polygons.
• Model urban cooling effects based on the canopy cover data.
• Assess changes in urban habitat connectivity based on the high vegetation cover.
• Integrate canopy data with building footprints for urban development planning.
• Validate remote sensing models using the LiDAR-derived canopy height methodology.

Strengths

• Data is derived from LiDAR acquired at an average resolution of 12ppm.
• Processing includes removal of non-vegetative surfaces using an NDVI layer from Pleiades satellite imagery.
• Canopy holes smaller than 1m² were filled to improve data continuity.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Due to complexity and high resolution, the dataset may draw slowly or appear to miss some trees.
• Row count is unknown, which may limit suitability assessment.
